University of Washington Health Sciences/UW Medicine study: Depression among young teens linked to cannabis use at 18

6 Aug

Often children who evidence signs of a substance abuse problem come from homes where there is a substance abuse problem. That problem may be generational. eMedicineHealth lists some of the causes of substance abuse:

Substance Abuse Causes
Use and abuse of substances such as cigarettes, alcohol, and illegal drugs may begin in childhood or the teen years. Certain risk factors may increase someone’s likelihood to abuse substances.
Factors within a family that influence a child’s early development have been shown to be related to increased risk of drug abuse.
o Chaotic home environment
o Ineffective parenting
o Lack of nurturing and parental attachment
Factors related to a child’s socialization outside the family may also increase risk of drug abuse.
o Inappropriately aggressive or shy behavior in the classroom
o Poor social coping skills
o Poor school performance
o Association with a deviant peer group
o Perception of approval of drug use behavior
http://www.emedicinehealth.com/substance_abuse/article_em.htm
Substance abuse is often a manifestation of other problems that child has either at home or poor social relations including low self-esteem. Dr. Alan Leshner summarizes the reasons children use drugs in why do Sally and Johnny use drugs? http://archives.drugabuse.gov/Published_Articles/Sally.html

Science Daily reported in: Depression among young teens linked to cannabis use at 18:

A study looking at the cumulative effects of depression in youth, found that young people with chronic or severe forms of depression were at elevated risk for developing a problem with cannabis in later adolescence.
The study led by UW Medicine researchers interviewed 521 students recruited from four Seattle public middle schools. Researchers used data from annual assessments when students were ages 12-15 and then again when they were 18. The results were published in the journal Addiction.
“The findings suggest that if we can prevent or reduce chronic depression during early adolescence, we may reduce the prevalence of cannabis use disorder,” said lead author Isaac Rhew, research assistant professor of psychiatry and behavioral sciences at the University of Washington School of Medicine.
What researchers called “a 1 standard deviation increase” in cumulative depression during early adolescence was associated with a 50 percent higher likelihood of cannabis-use disorder.
According to researchers, during the past decade cannabis has surpassed tobacco with respect to prevalence of use among adolescents. Cannabis and alcohol are the two most commonly used substances among youth in the United States. They pointed to one national study showing increases in prevalence of cannabis use disorder and alcohol use disorder in the United States, especially among young adults.
Longitudinal studies looking at the link between depression and later use of alcohol and cannabis, however, have been mixed. Some show a link. Others don’t. But most studies have assessed adolescent depression at a single point in time — not cumulatively, said the researchers. Further, there have been differences in how substance use has been measured ranging from the initiation of any use to heavier problematic forms of use.
The study oversampled for students with depressive and/or conduct problems. The researchers were surprised to see that the prevalence of cannabis and alcohol use disorder in this study was notably higher than national estimates with 21 percent meeting criteria for cannabis use disorder and 20 percent meeting criteria for alcohol use disorder at age 18.
What effect the easing of marijuana laws in Washington state had on the youth is unclear. Researchers said it would be informative to conduct a similar study in a state with more strict marijuana laws to understand whether the relationship between depression and cannabis misuse would still hold in areas where marijuana may be less accessible…. https://www.sciencedaily.com/releases/2017/07/170717151031.htm

Young people with chronic or severe depression are at elevated risk for developing a problem with cannabis in later adolescence, new research indicates.

The study, led by UW Medicine investigators, interviewed 521 students recruited from four Seattle public middle schools. Researchers used data from annual assessments when students were ages 12 to 15 and then again when they were 18. The results were published in the journal Addiction.
“The findings suggest that if we can prevent or reduce chronic depression during early adolescence, we may reduce the prevalence of cannabis use disorder,” said lead author Isaac Rhew, research assistant professor of psychiatry and behavioral sciences at the University of Washington School of Medicine.
What researchers called “a 1 standard deviation increase” in cumulative depression during early adolescence was associated with a 50 percent higher likelihood of cannabis-use disorder in the study.
During the past decade, cannabis use among adolescents has surpassed that of tobacco. Cannabis and alcohol are the two most commonly used substances among youth in the United States. They cited one national study showing increases in the prevalence of cannabis-use disorder and alcohol-use disorder in the United States, especially among young adults.
Longitudinal studies of depression and later use of alcohol and cannabis, however, have been mixed. Some show a link, others don’t. Most such studies have assessed adolescent depression at a single point in time – not cumulatively, the researchers noted. Further, previous research has measured substance use differently, ranging from initiation of any use to heavier, problematic use.
The study oversampled for students with depressive and/or conduct problems. The researchers were surprised by data indicating that the prevalence of cannabis- and alcohol-use disorder in this study was notably higher than national estimates, with 21 percent meeting criteria for cannabis-use disorder and 20 percent meeting criteria for alcohol-use disorder at age 18.
What effect the easing of marijuana laws in Washington state had on the youth is unclear. Researchers said it would be informative to conduct a similar study in a state with stricter marijuana laws to understand whether the relationship between depression and later cannabis misuse is similar.
The substance-abuse assessments of 18-year-olds occurred between 2007 and 2010. Washington state legalized medical cannabis in 1998 and its medical cannabis market expanded greatly after 2009, when the U.S. justice department issued a ruling known as the “Ogden Memo.” And in 2003, the city of Seattle made cannabis offenses the lowest enforcement priority for police and the city attorney.
The study was supported by funding from the National Institute of Mental Health and the National Institute on Drug Abuse, as well as funding from the University of Washington Alcohol and Drug Abuse Institute. Other authors include UW Medicine researchers Charles Fleming (psychiatry and the Center for the Study of Health and Risk Behaviors), Ann Vander Stoep (psychiatry and epidemiology), Elizabeth McCauley (psychiatry, pediatrics, psychology), and Semret Nicodimos (psychiatry and the Mental Health Assessment, Research & Training Center).

Marijuana Smokers Five Times More Likely to Develop an Alcohol Problem

Adults who use marijuana are five times more likely to develop an alcohol use disorder (AUD) —alcohol abuse or dependence— compared with adults who do not use the drug. And adults who already have an alcohol use disorder and use marijuana are more likely to see the problem persist. Results of a study by researchers at Columbia University’s Mailman School of Public Health and the City University of New York appear online in the journal Drug and Alcohol Dependence.

“Our results suggest that cannabis use appears to be associated with an increased vulnerability to developing an alcohol use disorder, even among those without any history of this,” said Renee Goodwin, PhD, associate professor of Epidemiology at the Mailman School of Public Health. “Marijuana use also appears to increase the likelihood that an existing alcohol use disorder will continue over time.”

The researchers analyzed data from 27,461 adults enrolled in the National Epidemiologic Survey on Alcohol and Related Conditions who first used marijuana at a time when they had no lifetime history of alcohol use disorders. The population was assessed at two time points. Adults who had used marijuana at the first assessment and again over the following three years (23 percent) were five times more likely to develop an alcohol use problem, compared with those who had not used marijuana (5 percent). Adult problem drinkers who did not use cannabis were significantly more likely to be in recovery from alcohol use disorders three years later.

“From a public health standpoint we recommend that further research be conducted to understand the pathways underlying these relationships as well as the degree to which various potentially vulnerable population subgroups — youth, for example — are at increased risk,” noted Goodwin. “If future research confirms these findings, investigating whether preventing or delaying first use of marijuana might reduce the risk of developing alcohol use disorders among some segments of the population may be worthwhile.”

Australian study: Frequent marijuana use among those under 17 may result in lower educational achievement

Simon Makin reported in the Scientific American article, Does Marijuana Harm the Brain?

The Claim
Casual cannabis use harms young people’s brains.
The Facts
A study found differences in the brains of users and nonusers, but it did not establish that marijuana use caused the variations or that they had any functional significance.
The Details
Researchers at Northwestern University and Harvard Medical School conducted MRI scans of two groups of 20 young adults ages 18 to 25. One group reported using marijuana at least once a week, smoking 11 joints a week on average, whereas the other had used it less than five times total and not at all during the last year. Neither group had any psychiatric disorders, and the users were psychiatrically assessed as not dependent on the drug.
The study focused on two brain regions involved in processing rewards, the nucleus accumbens and the amygdala. These areas create pleasurable experiences of things such as food and sex, as well as the high associated with drugs, and have been shown to change in animals given THC, the main psychoactive component of cannabis.
The researchers found that cannabis users had more gray matter density in the left nucleus accumbens and left amygdala, as well as differences in the shape of the left nucleus accumbens and right amygdala. The left nucleus accumbens also tended to be slightly larger in users. They concluded that recreational cannabis use might be associated with abnormalities in the brain’s reward system. News reports have proclaimed that scientists have shown that even casual cannabis use harms young people’s brains.
The Caveats
The most obvious problem with leaping to that conclusion is that the scans were conducted at only one point. This approach can compare the two groups, but it cannot prove cannabis caused any differences between them—or even that the differences represent changes over time. They could be preexisting variations, or cannabis use and brain changes may both be related to a third factor, such as tobacco (although the study did attempt to take levels of smoking into account)…..
Reality Check—Cannabis use has been found to:
• Cause dependence, at some point in their lives, in about 9 percent of people who try it.
• Impair various aspects of cognitive function, particularly memory. Impairments can remain for several days. One study showed that performance returns to nonusers’ levels after 28 days of abstinence, but evidence is mixed about how long the impairments last.
• Potentially reduce the volume of the hippocampus, which is critical for memory—but only after heavy and prolonged use. The evidence linking cognitive impairments to specific brain changes is inconclusive, and the degree to which such changes are reversible is hotly debated. http://www.scientificamerican.com/article/does-marijuana-harm-the-brain/

Science Daily reported a longitudinal study from Australia and New Zealand.

In Frequent cannabis use in adolescence linked with reduced educational attainment, other problems in young adults, Science Daily reported:

Individuals who are daily users of cannabis before age 17 are over 60% less likely to complete high school or obtain a degree compared to those who have never used the drug, new research published in The Lancet Psychiatry journal shows. The large meta-analysis also indicates that daily users of cannabis during adolescence are seven times more likely to attempt suicide, have an 18 times greater chance of cannabis dependence, and are eight times as likely to use other illicit drugs in later life.
“Our findings are particularly timely given that several US states and countries in Latin America have made moves to decriminalize or legalize cannabis, raising the possibility that the drug might become more accessible to young people”, says Richard Mattick, study author and Professor of Drug and Alcohol Studies at the National Drug and Alcohol Research Centre, University of New South Wales, in Australia.
Cannabis is the most widely used illicit drug globally and recent statistics have shown that in some countries adolescents are starting cannabis use at a younger age and more adolescents are using cannabis heavily. In England, 4% of 11-15 year olds report cannabis use in the past month, roughly 7% of US high-school seniors are daily or near-daily cannabis users, and in Australia, around 1% of 14-19 year olds are daily users of the drug, whilst 4% use weekly.
In this study, a team of Australian and New Zealand researchers combined individual-level data on up to 3765 participants who used cannabis from three large, long-running longitudinal studies to find out more about the link between the frequency of cannabis use before the age of 17 years (never, less than monthly, monthly or more, weekly or more, or daily) and seven developmental outcomes up to the age of 30 years (completing high school, obtaining a university degree, cannabis dependence, use of other illicit drugs, suicide attempt, depression, and welfare dependence)….

Summary

Background

Debate continues about the consequences of adolescent cannabis use. Existing data are limited in statistical power to examine rarer outcomes and less common, heavier patterns of cannabis use than those already investigated; furthermore, evidence has a piecemeal approach to reporting of young adult sequelae. We aimed to provide a broad picture of the psychosocial sequelae of adolescent cannabis use.
Methods

We integrated participant-level data from three large, long-running longitudinal studies from Australia and New Zealand: the Australian Temperament Project, the Christchurch Health and Development Study, and the Victorian Adolescent Health Cohort Study. We investigated the association between the maximum frequency of cannabis use before age 17 years (never, less than monthly, monthly or more, weekly or more, or daily) and seven developmental outcomes assessed up to age 30 years (high-school completion, attainment of university degree, cannabis dependence, use of other illicit drugs, suicide attempt, depression, and welfare dependence). The number of participants varied by outcome (N=2537 to N=3765).

Findings

We recorded clear and consistent associations and dose-response relations between the frequency of adolescent cannabis use and all adverse young adult outcomes. After covariate adjustment, compared with individuals who had never used cannabis, those who were daily users before age 17 years had clear reductions in the odds of high-school completion (adjusted odds ratio 0•37, 95% CI 0•20—0•66) and degree attainment (0•38, 0•22—0•66), and substantially increased odds of later cannabis dependence (17•95, 9•44—34•12), use of other illicit drugs (7•80, 4•46—13•63), and suicide attempt (6•83, 2•04—22•90).

Interpretation

Adverse sequelae of adolescent cannabis use are wide ranging and extend into young adulthood. Prevention or delay of cannabis use in adolescence is likely to have broad health and social benefits. Efforts to reform cannabis legislation should be carefully assessed to ensure they reduce adolescent cannabis use and prevent potentially adverse developmental effects.

University of Pennsylvania Annenberg Public Policy Center study: Drug testing high school students might not be effective

14 Jan

Moi wrote in Missouri high school to drug test students:
Fox News reported in the story, Missouri high school reportedly to use hair samples for random drug tests:
Beginning in the 2013-2014 school year, students at Rockhurst High School in Kansas City will be mandated to undergo random drug testing by submitting roughly 60 strands of hair to a staff member at the 1,000-student school, KSHB.com reports….
If a student tests positive for any substance, according to the new policy, a guidance counselor will be notified. The counselor will then notify the student’s parents to determine how to best help the child.
The student would then be given 90 days to be drug-free, with no notification sent to administrative personnel. The incident would only be noted in the student’s guidance file, which would later be destroyed upon graduation and will not be sent to colleges or universities. The document would only become public if subpoenaed, the website reports. http://www.foxnews.com/us/2013/01/31/missouri-high-school-reportedly-to-use-hair-samples-for-random-drug-tests/#ixzz2KXRqmSpX
The National Institute on Drug Abuse (Institute) has some great information about drug testing.
In Frequently Asked Questions About Drug Testing in Schools, the Institute discusses drug testing.
Why test teenagers at all?
Teens are especially vulnerable to drug abuse, when the brain and body are still developing. Most teens do not use drugs, but for those who do, it can lead to a wide range of adverse effects on the brain, the body, behavior and health.
Short term: Even a single use of an intoxicating drug can affect a person’s judgment and decisonmaking—resulting in accidents, poor performance in a school or sports activity, unplanned risky behavior, and the risk of overdosing.
Long term: Repeated drug abuse can lead to serious problems, such as poor academic outcomes, mood changes (depending on the drug: depression, anxiety, paranoia, psychosis), and social or family problems caused or worsened by drugs.
Repeated drug use can also lead to the disease of addiction. Studies show that the earlier a teen begins using drugs, the more likely he or she will develop a substance abuse problem or addiction. Conversely, if teens stay away from drugs while in high school, they are less likely to develop a substance abuse problem later in life….
Is random drug testing of students legal?
In June 2002, the U.S. Supreme Court broadened the authority of public schools to test students for illegal drugs. Voting 5 to 4 in Pottawatomie County v. Earls, the court ruled to allow random drug tests for all middle and high school students participating in competitive extracurricular activities. The ruling greatly expanded the scope of school drug testing, which previously had been allowed only for student athletes.
Just because the U.S. Supreme Court said student drug testing for adolescents in competitive extracurricular activities is constitutional, does that mean it is legal in my city or state?
A school or school district that is interested in adopting a student drug testing program should seek legal expertise so that it complies with all federal, state, and local laws. Individual state constitutions may dictate different legal thresholds for allowing student drug testing. Communities interested in starting student drug testing programs should become familiar with the law in their respective states to ensure proper compliance. http://www.drugabuse.gov/related-topics/drug-testing/faq-drug-testing-in-schools
The primary issue is whether students have privacy rights.
Your Debate.com summarizes the pros and cons of School Drug Testing:
PRO 1
The main purpose of random school drug testing is not to catch kids using drugs, it to keep them from ever using them. Once their using drugs its harder for them to break their addiction. With many employers drug testing its very important for a kid’s future not to use drugs. Drug use is responsible for many crimes. Its worth the inconvenience for all our future.
CON 2
One of the fundamental features of our legal system is that we are presumed innocent of any wrongdoing unless and until the government proves otherwise. Random drug testing of student athletes turns this presumption on its head, telling students that we assume they are using drugs until they prove to the contrary with a urine sample.
CON 3
“If school officials have reason to believe that a particular student is using drugs, they already have the power to require that student to submit to a drug test,” said ACLU-NJ Staff Attorney David Rocah.
CON 4
The constitutional prohibition against “unreasonable” searches also embodies the principle that merely belonging to a certain group is not a sufficient reason for a search, even if many members of that group are suspected of illegal activity. Thus, for example, even if it were true that most men with long hair were drug users, the police would not be free to stop all long haired men and search them for drugs.
PRO 5
Peer pressure is the greatest cause of kids trying drugs. If by testing the athletes or other school leaders, we can get them to say no to drugs, it will be easier for other kids to say no.
CON 6
Some also argue that students who aren’t doing anything wrong have nothing to fear. This ignores the fact that what they fear is not getting caught, but the loss of dignity and trust that the drug test represents. And we should all be afraid of government officials who believe that a righteous cause warrants setting aside bedrock constitutional protections. The lesson that our schools should be teaching is respect for the Constitution and for students’ dignity and privacy, not a willingness to treat cherished constitutional principles as mere platitudes. http://www.youdebate.com/DEBATES/school_drug_testing.HTM
See, What Are the Benefits of Drug Testing? http://www.livestrong.com/article/179407-what-are-the-benefits-of-drug-testing/ https://drwilda.com/2013/02/11/missouri-high-school-to-drug-test-students/
Maanvi Singh of NPR reported in the study, Drug Tests Don’t Deter Drug Use, But School Environment Might:
Schools that do random drug testing say it helps students say no to illegal drugs, while critics say it’s an invasion of privacy. But feeling good about school may affect students’ drug use more than the threat of testing.
A survey of high school students found that the possibility that they might face drug testing didn’t really discourage students from alcohol, cigarettes or marijuana. But students who thought their school had a positive environment were less apt to try cigarettes and pot.
Those students were about 20 percent less likely to try smoke pot and 15 percent less likely to light up a cigarette than students who didn’t feel that their school was a positive place, the survey found. And the trend held true, more or less, regardless of demographic or geographic factors.
Researchers from the University of Pennsylvania’s Annenberg Public Policy Center looked at 361 high school students across the country. The students were initially interviewed in 2008 as part of the more general National Annenberg Survey of Youth. A year later, researchers followed up and asked participants whether they had tried alcohol, or smoked cigarettes or marijuana.
The research was published Monday in the Journal of Studies on Alcohol and Drugs. Dan Romer, an author of the study who directs Annenberg’s Adolescent Communication Institute, says he wasn’t surprised by the results. “In a school with a good climate, the kids will respect what the teachers say more,” he tells Shots.
The key, Romer says, is that students need to understand why a school has certain disciplinary policies. “It basically boils down to how much respect everybody feels toward each other,” he says.
Proponents of random drug testing say it can act as a deterrent, or as a way to identify students in need of help. The Supreme Court has upheld the constitutionality of the practice twice, in 1995 and 2002. But the court limited its use to students participating in competitive extracurricular activities.
A school that has a positive climate might also practice drug testing, Romer said – the two aren’t mutually exclusive. But this study suggests that administrators concerned about substance abuse might want to try programs that encourage a more respectful school climate before turning to drug testing.
This study is by no means conclusive. It doesn’t distinguish between schools that implement randomized drug testing and those that only test students suspected of drug use. And it doesn’t look at whether other drug education programs might have influenced the results.
These findings reinforce previous research that casts doubt on the effectiveness of drug testing as a deterrent. A 2010 study from the University of Michigan found that in schools with drug testing, students were more likely to turn from marijuana to other illicit drugs.
One thing that neither a drug policy nor a positive environment seemed to affect was underage drinking. “It suggests to us that alcohol may be so accepted now in high school culture,” Romer says, “that kids think if you’re at a party you should be able to drink.” http://www.npr.org/blogs/health/2014/01/14/262466903/drug-tests-dont-deter-drug-use-but-school-environment-might?utm_medium=Email&utm_source=share&utm_campaign=

Here is the press release from University of Pennsylvania’s Annenberg Public Policy Center:
School drug tests ineffective but a ‘positive climate’ might work
Monday, January 13th, 2014
A national study of teenagers suggests that school drug testing did not deter them from starting to smoke tobacco or marijuana or drink alcohol. But in high schools that had a “positive school climate,” teens were less likely to start smoke cigarettes or marijuana.
Research published in the January issue of the Journal of Studies on Alcohol and Drugs compared the effectiveness over one year of school policies of student drug testing, which are in place in an estimated 20 percent of U.S. high schools, with a positive school climate.
“The bad news is that a policy of drug testing has no effect on students starting to use alcohol, cigarettes or marijuana,” said study co-author Dan Romer, associate director of the Annenberg Public Policy Center (APPC) at the University of Pennsylvania. “There’s also no effect on escalating the use of those substances.”
The study found, however, that students in schools with a positive school climate reported a lower rate of starting to use cigarettes and marijuana, and a slower escalation of smoking at the one-year follow-up interview. Students in schools with positive climates were 15 percent less likely to start smoking cigarettes and 20 percent less likely to start using marijuana than students at schools without positive climates, the study shows.
Student drug testing “is a relatively ineffective drug-prevention policy,” wrote the researchers, Dan Romer and Sharon R. Sznitman, an APPC Distinguished Research Fellow and a lecturer at the School of Public Health, University of Haifa, Israel. “On the other hand, interventions that improve school climate may have greater efficacy.” The study added that “whole school” health efforts that engage students, faculty and parents, and promote a sense of security and well-being have been found to reduce substance abuse.
Neither drug testing nor school climate affected the start of drinking alcohol.

Student Drug Testing and Positive School Climates: Testing the Relation Between Two School Characteristics and Drug Use Behavior in a Longitudinal Study [OPEN ACCESS]
Sharon R. Sznitman, Daniel Romer
Objective: Fostering positive school climates and student drug testing have been separately proposed as strategies to reduce student drug use in high schools. To assess the promise of these strategies, the present research examined whether positive school climates and/or student drug testing successfully predicted changes in youth substance use over a 1-year follow-up. Method: Two waves of panel data from a sample of 361 high school students, assessed 1 year apart, were analyzed. Changes in reported initiation and escalation in frequency of alcohol, cigarette, and marijuana use as a function of perceived student drug testing and positive school climates were analyzed, while we held constant prior substance use. Results: Perceived student drug testing was not associated with changes in substance use, whereas perceived positive school climates were associated with a reduction in cigarette and marijuana initiation and a reduction in escalation of frequency of cigarette use at 1-year follow-up. However, perceived positive school climates were not associated with a reduction in alcohol use. Conclusions: Student drug testing appears to be less associated with substance use than positive school climates. Nevertheless, even favorable school climates may not be able to influence the use of alcohol, which appears to be quite normative in this age group. (J. Stud. Alcohol Drugs, 75, 65–73, 2014)

Northwestern University study: Young adolescent use of marijuana results in changes to the brain structure

23 Dec

Often children who evidence signs of a substance abuse problem come from homes where there is a substance abuse problem. That problem may be generational. eMedicineHealth lists some of the causes of substance abuse:

Substance Abuse Causes
Use and abuse of substances such as cigarettes, alcohol, and illegal drugs may begin in childhood or the teen years. Certain risk factors may increase someone’s likelihood to abuse substances.
Factors within a family that influence a child’s early development have been shown to be related to increased risk of drug abuse.
o Chaotic home environment
o Ineffective parenting
o Lack of nurturing and parental attachment
Factors related to a child’s socialization outside the family may also increase risk of drug abuse.
o Inappropriately aggressive or shy behavior in the classroom
o Poor social coping skills
o Poor school performance
o Association with a deviant peer group
o Perception of approval of drug use behavior
http://www.emedicinehealth.com/substance_abuse/article_em.htm

Substance abuse is often a manifestation of other problems that child has either at home or poor social relations including low self-esteem. Dr. Alan Leshner summarizes the reasons children use drugs in why do Sally and Johnny use drugs? http://archives.drugabuse.gov/Published_Articles/Sally.html

Anahad O’Connor reported in the New York Times article, Increasing Marijuana Use in High School Is Reported:

A new federal report shows that the percentage of American high school students who smoke marijuana is slowly rising, while the use of alcohol and almost every other drug is falling.
The report raises concerns that the relaxation of restrictions on marijuana, which can now be sold legally in 20 states and the District of Columbia, has been influencing use of the drug among teenagers. Health officials are concerned by the steady increase and point to what they say is a growing body of evidence that adolescent brains, which are still developing, are susceptible to subtle changes caused by marijuana.
“The acceptance of medical marijuana in multiple states leads to the sense that if it’s used for medicinal purposes, then it can’t be harmful,” said Dr. Nora D. Volkow, director of the National Institute on Drug Abuse, which issued the report. “This survey has shown very consistently that the greater the number of kids that perceive marijuana as risky, the less that smoke it.” Starting early next year, recreational marijuana use will also be legal in Colorado and Washington.
Experts debate the extent to which heavy marijuana use may cause lasting detriment to the brain. But Dr. Volkow said that one way marijuana might affect cognitive function in adolescents was by disrupting the normal development of white matter through which cells in the brain communicate.
According to the latest federal figures, which were part of an annual survey, Monitoring the Future, more than 12 percent of eighth graders and 36 percent of seniors at public and private schools around the country said they had smoked marijuana in the past year. About 60 percent of high school seniors said they did not view regular marijuana use as harmful, up from about 55 percent last year.
The report looked at a wide variety of drugs and substances. It found, for example, that drinking was steadily declining, with roughly 40 percent of high school seniors reporting having used alcohol in the past month, down from a peak of 53 percent in 1997. Abuse of the prescription painkiller Vicodin is half what it was a decade ago among seniors; cocaine and heroin use are at historic lows in almost every grade.
Cigarette smoking has also fallen precipitously in recent years. For the first time since the survey began, the percentage of students who smoked a cigarette in the past month dropped below 10 percent. Roughly 8.5 percent of seniors smoke cigarettes on a daily basis, compared with 6.5 percent who smoke marijuana daily, a slight increase from 2010.
Studies show that the concentration of THC in marijuana, its psychoactive ingredient, has tripled since the early 1990s, and Dr. Volkow said there was concern that the rising use and increased potency could affect the likelihood of car accidents and could lower school performance.
“What is most worrisome is that we’re seeing high levels of everyday use of marijuana among teenagers,” Dr. Volkow said. “That is the type that’s most likely to have negative effects on brain function and performance.”

Abstract
Cannabis use is associated with working memory (WM) impairments; however, the relationship between cannabis use and WM neural circuitry is unclear. We examined whether a cannabis use disorder (CUD) was associated with differences in brain morphology between control subjects with and without a CUD and between schizophrenia subjects with and without a CUD, and whether these differences related to WM and CUD history. Subjects group-matched on demographics included 44 healthy controls, 10 subjects with a CUD history, 28 schizophrenia subjects with no history of substance use disorders, and 15 schizophrenia subjects with a CUD history. Large-deformation high-dimensional brain mapping with magnetic resonance imaging was used to obtain surface-based representations of the striatum, globus pallidus, and thalamus, compared across groups, and correlated with WM and CUD history. Surface maps were generated to visualize morphological differences. There were significant cannabis-related parametric decreases in WM across groups. Similar cannabis-related shape differences were observed in the striatum, globus pallidus, and thalamus in controls and schizophrenia subjects. Cannabis-related striatal and thalamic shape differences correlated with poorer WM and younger age of CUD onset in both groups. Schizophrenia subjects demonstrated cannabis-related neuroanatomical differences that were consistent and exaggerated compared with cannabis-related differences found in controls. The cross-sectional results suggest that both CUD groups were characterized by WM deficits and subcortical neuroanatomical differences. Future longitudinal studies could help determine whether cannabis use contributes to these observed shape differences or whether they are biomarkers of a vulnerability to the effects of cannabis that predate its misuse.

Here is the press release from Northwestern University:

Marijuana Users Have Abnormal Brain Structure and Poor Memory
Drug abuse appears to foster brain changes that resemble schizophrenia
December 16, 2013 | by Marla Paul
• The younger drug abuse starts, the more abnormal the brain
CHICAGO — Teens who were heavy marijuana users — smoking it daily for about three years — had abnormal changes in their brain structures related to working memory and performed poorly on memory tasks, reports a new Northwestern Medicine® study.
A poor working memory predicts poor academic performance and everyday functioning.
The brain abnormalities and memory problems were observed during the individuals’ early twenties, two years after they stopped smoking marijuana, which could indicate the long-term effects of chronic use. Memory-related structures in their brains appeared to shrink and collapse inward, possibly reflecting a decrease in neurons.
The study also shows the marijuana-related brain abnormalities are correlated with a poor working memory performance and look similar to schizophrenia-related brain abnormalities. Over the past decade, Northwestern scientists, along with scientists at other institutions, have shown that changes in brain structure may lead to changes in the way the brain functions.
This is the first study to target key brain regions in the deep subcortical gray matter of chronic marijuana users with structural MRI and to correlate abnormalities in these regions with an impaired working memory. Working memory is the ability to remember and process information in the moment and — if needed — transfer it to long-term memory. Previous studies have evaluated the effects of marijuana on the cortex, and few have directly compared chronic marijuana use in otherwise healthy individuals and individuals with schizophrenia.
The younger the individuals were when they started chronically using marijuana, the more abnormally their brain regions were shaped, the study reports. The findings suggest that these regions related to memory may be more susceptible to the effects of the drug if abuse starts at an earlier age.
“The study links the chronic use of marijuana to these concerning brain abnormalities that appear to last for at least a few years after people stop using it,” said lead study author Matthew Smith, an assistant research professor in psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine. “With the movement to decriminalize marijuana, we need more research to understand its effect on the brain.”
The paper was published Dec. 16 in the journal Schizophrenia Bulletin.
In the U.S., marijuana is the most commonly used illicit drug and young adults have the highest — and growing — prevalence of use. Decriminalization of the drug may lead to greater use.
Because the study results examined one point in time, a longitudinal study is needed to definitively show if marijuana is responsible for the brain changes and memory impairment. It is possible that the abnormal brain structures reveal a pre-existing vulnerability to marijuana abuse. But evidence that the younger a subject started using the drug the greater his brain abnormality indicates marijuana may be the cause, Smith said.
The groups in the study started using marijuana daily between 16 to 17 years of age for about three years. At the time of the study, they had been marijuana free for about two years. A total of 97 subjects participated, including matched groups of healthy controls, subjects with a marijuana use disorder, schizophrenia subjects with no history of substance use disorders, and schizophrenia subjects with a marijuana use disorder. The subjects who used marijuana did not abuse any other drugs.
Few studies have examined marijuana’s effect on the deep regions in the brain — the ‘subcortical gray matter’ below the noodle-shaped cortex. The study also is unique in that it looked at the shapes of the striatum, globus pallidus and thalamus, structures in the subcortex that are critical for motivation and working memory.
The Marijuana and Schizophrenia Connection
Chronic use of marijuana may contribute to changes in brain structure that are associated with having schizophrenia, the Northwestern research shows. Of the 15 marijuana smokers who had schizophrenia in the study, 90 percent started heavily using the drug before they developed the mental disorder. Marijuana abuse has been linked to developing schizophrenia in prior research.
“The abuse of popular street drugs, such as marijuana, may have dangerous implications for young people who are developing or have developed mental disorders,” said co-senior study author John Csernansky, M.D., chair of psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine and Northwestern Memorial Hospital. “This paper is among the first to reveal that the use of marijuana may contribute to the changes in brain structure that have been associated with having schizophrenia.”
Chronic marijuana use could augment the underlying disease process associated with schizophrenia, Smith noted. “If someone has a family history of schizophrenia, they are increasing their risk of developing schizophrenia if they abuse marijuana,” he said.
While chronic marijuana smokers and chronic marijuana smokers with schizophrenia both had brain changes related to the drug, subjects with the mental disorder had greater deterioration in the thalamus. That structure is the communication hub of the brain and is critical for learning, memory and communications between brain regions. The brain regions examined in this study also affect motivation, which is already notably impaired in people with schizophrenia.
“A tremendous amount of addiction research has focused on brain regions traditionally connected with reward/aversion function, and thus motivation,” noted co-senior study author Hans Breiter, M.D., professor of psychiatry and behavioral sciences and director of the Warren Wright Adolescent Center at Feinberg and Northwestern Memorial. “This study very nicely extends the set of regions of concern to include those involved with working memory and higher level cognitive functions necessary for how well you organize your life and can work in society.”
“If you have schizophrenia and you frequently smoke marijuana, you may be at an increased risk for poor working memory, which predicts your everyday functioning,” Smith said.
The research was supported by grants R01 MH056584 and P50 MH071616 from the National Institute of Mental Health and grants P20 DA026002 and RO1 DA027804 from National Institute of Drug Abuse, all of the National Institutes of Health.

Questions to Ask a Treatment Facility

The U.S. Department of Health and Human Services, Center for Substance Abuse Treatment (Center), lists the questions that should be asked of a treatment center. http://findtreatment.samhsa.gov/faq.htm Assuming you are not one of those ill-advised parents who supply their child with alcohol or drugs like marijuana in an attempt to be hip or cool, suspicions that your child may have a substance abuse problem are a concern. Confirmation that your child has a substance abuse problem can be heartbreaking. Even children whose parents have seemingly done everything right can become involved with drugs. The best defense is knowledge about your child, your child’s friends, and your child’s activities
