“Sending the Wrong Message”: Did Medical Marijuana Legalization in California Change Attitudes about and use of Marijuana?

This study was designed to assess the affect of legalization of medical marijuana on drug-related attitudes and use among youths and young adults in selected communities in California and other states. Telephone survey data, collected as part of a study of the Robert Wood Johnson Foundation's Fighting Back initiative, was utilized to examine reported attitudes about and use of drugs in California and other states before and after Californians passed Proposition 215 in 1996. Descriptive, bivariate, and logistic regression analyses were used to examine attitudes and use among 16 to 25 year olds in California and 10 other states. This study found that although some marijuana-related attitudes changed between 1995 and 1999, use did not increase. These findings suggest that recent policy changes have had little impact on marijuana-related behavior.
