The Influences of Health Beliefs and Identity on Adolescent Marijuana and Tobacco Co-Use

Among youth, the co-use of marijuana and tobacco is highly prevalent, yet a considerable gap remains in the drug-prevention literature pertaining to such co-use. In particular, the prevention field lacks research exploring how adolescents understand the health implications of smoking these two substances in combination. In this article, we draw on qualitative interviews with adolescents from three communities in British Columbia, Canada, and describe the health beliefs and social identities that they associated with smoking marijuana and tobacco. We argue that smoking prevention and cessation initiatives targeting adolescents must address both marijuana and tobacco. Such initiatives must also be designed to identify and address how adolescents frame the potential health harms associated with smoking these substances.
