In the August 2014 edition of the Journal of Adolescent Health Esther Choo and colleagues from Brown University, Providence, Rhode Island examine the impact of state-level legalization of medical marijuana on accessibility and appeal of marijuana to young people by comparing trends in adolescent marijuana use between states with and without legalization of medical marijuana. Using data from the Youth Risk Behavioral Surveillance Survey (1991 and 2011) they analysed data from a sample of 11,703,100 students. They found that whilst across the USA past-month marijuana use was common (20.9%, 95% confidence interval 20.3–21.4) there was no increased probability of marijuana use related to medical marijuana policy change and they conclude that they did not find increases in adolescent marijuana use related to legalization of medical marijuana.
