“Tobacco and cannabis are frequently used in combination and cannabis co-use may lead to poor tobacco cessation outcomes. Therefore, it is important to explore if cannabis co-use is associated with a reduced likelihood of achieving successful tobacco abstinence among treatment-seeking tobacco smokers.
The present study examined whether current cannabis use moderated tobacco cessation outcomes after 12 weeks of pharmacological treatment with adjunctive behavioral counseling.
RESULTS:
Controlling for rate of nicotine metabolism, treatment arm, age, sex, alcohol, and level of nicotine dependence, cannabis users were as successful at achieving biochemically verified 7-day point prevalence abstinence compared to tobacco-only smokers.
CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE:
Findings suggest that cannabis use does not hinder the ability to quit tobacco smoking.”
