ScienceDaily Summary:
A new study raises questions about whether there is a need to revise prevention programming for youth as the availability, visibility and legal status of marijuana changes. The report found that adolescents who saw advertising for medical marijuana were more likely to either report using marijuana or say they planned to use the substance in the future.

ScienceDaily Summary:

Large proportions of high school students normally at low risk for marijuana use (e.g., non-cigarette-smokers, religious students, those with friends who disapprove of use) reported intention to use marijuana if it were legal, a tumblr post reports. National support for marijuana legalization is increasing in the United States. Recreational use was recently legalized in the states of Colorado and Washington; other states across the country are expected to follow suit. To date, an additional 15 states have decriminalized marijuana use, and 19 states and the District of Columbia now allow medical marijuana to be prescribed.

ScienceDaily’s story further reports that “The researchers found that the data collected by the Monitoring The Future Study and analyzed by Dr. Palamar and his colleagues indicate that ten percent of non-lifetime marijuana users reported that they would try marijuana if legal.”

WTR-RI Research & Analysis Team Note:

According to the abstract for this study, “A questionnaire was administered to 2043 14–15-year-olds from Barcelona who were followed-up and re-interviewed after 15 months. … Among matched students, 23.7% of non-users at baseline had started to consume 15 months later (23.0% boys and 24.2% girls). Among those who had reported occasional cannabis use, 30.3% reported consumption during the previous month at the follow-up survey. … Cannabis initiation was facilitated by legal drug use, favorable attitudes and context-related variables.”  (underscoring ours)
