Background: Because marijuana is becoming more accessible and perceived norms of use are becoming increasingly more favorable, research is needed to understand characteristics of marijuana acquisition among adolescents. Purpose: The study purpose was to examine whether sources and locations where adolescent users obtain and use marijuana differed based on past month use, age of first use, time since last used, number of days used in the past month, perceived ease of access, perceived peer use, and demographics. Methods: We conducted a secondary data analysis (n = 3,102) of the National Survey on Drug Use and Health. Univariate and multivariable logistic regression models were performed. Results: Adolescents at highest risk for buying marijuana were male, older, used in the past month, and older when they first used. Adolescents at highest risk for buying marijuana inside a home/apartment/dorm were more likely to have used in the past month. Adolescents at highest risk for buying marijuana outside in a public area were African American and used 6-19 days in the past month. Discussion: Because marijuana is becoming more accessible, preventionists should continue monitoring acquisitions. Translation to Health Education Practice: Findings can be used to assist health educators to more thoroughly understand marijuana acquisition among adolescents.
