    joint_budThe percentage of young people who believe that they can readily access marijuana has fallen significantly since 2002, according to data published online ahead of print in the Journal of Studies on Alcohol and Drugs.

    A team of investigators from Boston University, the University of Texas at Austin, the University of North Carolina, and St. Louis University examined trends in perceived cannabis access among adolescents for the years 2002 to 2015.

    Authors reported: “[W]e observed a 27 percent overall reduction in the relative proportion of adolescents ages 12 to 17 and a 42 percent reduction among those ages 12 to 14 reporting that it would be ‘very easy’ to obtain marijuana. This pattern was uniformly observed among youth in all sociodemographic subgroups.”

    They concluded, “Despite the legalization of recreational and medical marijuana in some states, our findings suggest that … perceptions that marijuana would be very easy to obtain are on the decline among American youth.”

    The new data is consistent with figures published last year by the US Centers for Disease Control and Prevention, which reported, “From 2002 to 2014, … perceived availability [of marijuana] decreased by 13 percent among persons aged 12–17 years and by three percent among persons aged 18?25 years [old].”

    no_marijuanaFewer young people today identify as current users of cannabis as compared to 2002, according to national survey data released today by the US Department of Health and Human Services, Substance Abuse and Mental Health Services Administration.

    The 2016 National Survey on Drug Use and Health report finds that 6.5 percent of respondents between the ages of 12 and 17 report having consumed cannabis within the past 30 days – a decrease of 21 percent since 2002 and the lowest percentage reported by the survey in 20 years. Adolescents’ use of alcohol and tobacco also declined significantly during this same period.

    The findings are similar to those compiled by the University of Michigan which also reports long-term declines in young people’s marijuana use, which have fallen steadily nationwide since 1996.

    The new SAMHSA data acknowledges an increase in the percentage of respondents ages 18 or older who report using cannabis, a trend that has similarly been identified in other national surveys. By contrast, rates of alcohol abuse have been steadily declining for over a decade among this same age group. Rates of problematic cannabis use by those over the age of 18 have largely held steady since 2002, and have fallen substantially among adolescents.

    no_marijuanaYet another study has once again affirmed that the regulation of marijuana for medical or recreational purposes is not associated with increases in problematic cannabis use by young people.

    Writing in the Journal of Clinical Psychiatry, federal investigators from the US National Institute on Drug Abuse and the Substance Abuse Mental Health Services Administration evaluated marijuana use rates among young people (ages 12 to 17) between the years 2002 and 2014.

    Researchers reported that the prevalence of past-year cannabis use by youth fell 17 percent during this time period. The prevalence of problematic use by young people fell by 25 percent – with a downward trend starting in 2011.

    “In the United States, compared to 2002, even after adjusting for covariates, cannabis use decreased among youth during 2005-2014, and cannabis use disorder declined among youth cannabis users during 2013-2014,” authors concluded.

    The study’s findings are consistent with those of numerous other papers reporting no uptick in youth marijuana use or abuse following the enactment of marijuana regulation, including those here, here, here, here, here, here, and here.

    An abstract of the study, “Cannabis use and cannabis use disorders in the United States, 2002-2014,” appears online here.

    no_marijuanaThe enactment of medical marijuana laws is not associated with increased rates of problematic cannabis use, according to data published online in the journal Addiction.

    Columbia University investigators assessed cannabis use trends in states in the years following the passage of medicalization. They reported “no significant change in the prevalence of past-month marijuana use among adolescents or young adults (those ages 18 to 25)” following legalization. They also found no evidence of increased cannabis abuse or dependence by either young people or adults. States with largely unregulated medical programs were associated with increased self-reported use by adults age 26 and older, but states with stricter programs were not.

    The study’s findings are consistent with those of numerous other papers reporting no uptick in youth marijuana use or abuse following medical marijuana regulation, including those here, here, here, here, here, and here. The findings contradict those of a recent, widely publicized paper in JAMA Psychiatry which speculated that medical marijuana laws may increase the prevalence of cannabis use disorder among adults.

    no_marijuanaSelf-reported marijuana use continues to fall among younger teens, according to federally commissioned, nationwide survey data compiled by the University of Michigan.

    Results from the 2016 edition of the Monitoring the Future survey find that marijuana use by 8th-graders and 10th-graders is declining year by year. Further, a greater percentage of younger teens now say that their ability to obtain marijuana is more difficult than ever before.

    Marijuana use patterns among 12th-graders have held steady since 2011, the survey reported.

    Approximately 50,000 students are surveyed annually as part of the University of Michigan study.

    Since the mid-1990s, self-reported lifetime use of cannabis has fallen 44 percent among 8th-graders, 30 percent among 10th-graders, and ten percent among 12th-graders. Twenty-nine states have legalized the medical use of cannabis, and eight of those states have also regulated the adult use of marijuana, since that time.

    Overall, teens’ self-reported use of alcohol and/or any illicit substance aside from marijuana is at a historic low.

    Previous federally funded surveys by the US Centers for Disease Control and others have similarly reported that changes in statewide marijuana laws are not associated with rising levels of youth use.
