The use of cannabis during adolescence is not associated with structural brain differences in adulthood, according to longitudinal data published in the journal Drug and Alcohol Dependence. Researchers concluded, concluded, “[T]he patterns of cannabis use typically seen in community-dwelling adolescents does not appear to have lasting effects on brain structure.”
The establishment of medical cannabis dispensaries within close proximity of schools does not make teens more susceptible to using marijuana, according to data published in the Journal of Adolescent Health. Authors concluded, “We did not find empirical support of the associations of medical marijuana availability, price, and product variety around schools with adolescents’ marijuana use and susceptibility to use … in the future.”
State laws reducing minor marijuana possession offenses from criminal to civil violations (aka decriminalization) are associated with dramatic reductions in drug-related arrests, and are not linked to any uptick in youth cannabis use, according to data published by researchers at Washington University and the National Bureau of Economic Research.
The enactment of statewide laws regulating the use and distribution of cannabis for medical purposes is not associated with increased marijuana use among young people, according to a review of relevant studies published online ahead of print in the journal Addiction. Authors concluded, “In summary, current evidence does not support the hypothesis that MML passage is associated with increased marijuana use prevalence among adolescents in states that have passed such laws.”
Neither the occasional nor the heavy use of marijuana by adolescents is associated with decreased motivation, according to clinical data published online ahead of print in the journal Substance Use & Misuse. Authors reported: “After controlling for confounds, no significant differences were observed between regular and light users on any motivation index.”
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.”
Fewer 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.
Yet 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. “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 enactment of medical marijuana laws is not associated with increased rates of problematic cannabis use, according to data published online in the journal Addiction.
Self-reported marijuana use continues to fall among younger teens, according to federally commissioned, nationwide survey data compiled by the University of Michigan.
