The role of marijuana use etiquette in avoiding targeted police enforcement.

Internationally, where marijuana is illegal, users follow etiquette rules that prevent negative consequences of use. In this study, adherence to etiquette is hypothesized to reduce likelihood of marijuana-related police stop/search and arrest. Ethnographers administered group surveys to a diverse, purposive sample of 462 marijuana-using peer groups in several areas of New York City. Findings indicated that lack of etiquette was associated with dramatically higher likelihood of police stop/search or arrest only for users who were Black, male, and/or recruited from Harlem/South Bronx. If these users followed a few identified etiquette rules, their risk of police stop/search or arrest was comparable to that of other users. Implications are that etiquette represents an intentional conscientiousness about marijuana use. Groups that are specially targeted for anti-marijuana enforcement can remediate that heightened risk by following marijuana etiquette.
