    cropsThe passage of medical marijuana legalization is associated with reduced traffic fatalities among younger drivers, according to data published online ahead of print in the American Journal of Public Health.

    Investigators from Columbia University in New York and the University of California at Davis analyzed traffic fatality data from the years 1985 to 2014.

    They reported that states with medical cannabis laws had lower overall traffic fatality rates compared to states where cannabis is illegal, and that there was an immediate decline in motor vehicle deaths following the establishment of a legal cannabis market – particularly among those under 44 years of age.

    Authors concluded: “[O]n average, MMLs (medical marijuana laws) states had lower traffic fatality rates than non-MML states. …. MMLs are associated with reductions in traffic fatalities, particularly pronounced among those aged 25 to 44 years. … It is possible that this is related to lower alcohol-impaired driving behavior in MML-states.”

    An abstract of the study, “US traffic fatalities, 1985-2014, and their relationship to medical marijuana laws,” appears online here.

    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.

    no_marijuanaChanges in marijuana’s legal status under state law is not associated with increased cannabis use or with its perceived availability by young people, according to pair of recently published studies.

    In the first study, published online in the journal Substance Use & Misuse, researchers at Columbia University in New York surveyed the marijuana use habits of a national sampling of 1,310 adolescents between the years 2013 and 2015. Investigators assessed whether respondents from states with liberalized cannabis policies were more likely to acknowledge having consumed cannabis compared to those residing in jurisdictions where the substance remains criminally prohibited.

    Authors reported that the study’s findings “failed to show a relationship between adolescents’ use of marijuana and state laws regarding marijuana use.” … [They] suggest that eased sanctions on adult marijuana use are not associated with higher prevalence rates of marijuana use among adolescents.”

    In the second study, published in the journal Drug and Alcohol Dependence, a team of investigators from Columbia University, the University of California at Davis, and Boston University examined the relationship between medical cannabis laws and the prevalence of marijuana availability and use by both adolescents and by those age 26 or older. Authors reported no changes over a nine-year period (2004 to 2013) with regard to the past-month prevalence of marijuana use by those ages 12 to 17 or by those between the ages of 18 and 25. Those age 25 and younger also experienced no change in their perception of marijuana’s availability. By contrast, self-reported marijuana use and availability increased among adults age 26 or older over this same time period.

    The conclusions are similar to those of numerous separate studies reporting that changes in marijuana’s legal status are not associated with any uptick in teens’ use of the substance, such as those here, here, here, and here.

    Abstracts of the two studies, “Is the Legalization of Marijuana Associated With Its Use by Adolescents?” and “State-level medical marijuana laws, marijuana use and perceived availability of marijuana among the general U.S. population,” appear online here and here.

    legalization_pollSixty-three percent of Americans age 18 and older favor making the use of marijuana legal, according to national polling results compiled by the Public Religion Research Institute’s American Values Survey.

    The percentage is the highest ever reported by the poll, and marks a 30 percent increase in public support for legalization since 2014.

    The poll possesses a margin or error of +/- 2.8 percentage points.

    The results come only days after separate surveys released by the Pew Research Center and by Gallup also reported that Americans’ support for legalizing marijuana is at an all-time high.

    Legalize marijuanaSixty percent of Americans believe that “the use of marijuana should be legal,” according to nationwide polling data released today by Gallup. The percentage is the highest level of support ever reported by the polling group, and represents more than a doubling in public support over the past two decades.

    The data closely follows the release of polling data compiled by the Pew Research Center showing a similar, dramatic shift in public opinion in favor of legalization.

    Those ages 18 to 34 (77 percent), Independents (70 percent), and Democrats (67 percent) were most likely to endorse legalization in the Gallup poll. Support was weakest among Republicans (42 percent) and those age 55 or older (45 percent).

    The poll possesses a margin of error of +/- four percentage points.
