Key Points

This research aims to evaluate how cannabis use influences tobacco cessation success rates.
Prospective non-randomized trial
Assessment of tobacco cessation outcomes
Comparison of results based on cannabis co-use status
Regular cannabis co-use negatively impacted tobacco abstinence
Effect particularly evident in younger to middle-aged adults
Incorporating cannabis use in tobacco treatments may enhance cessation outcomes

Abstract

This is the first prospective study designed to compare tobacco cessation outcomes by cannabis co-use status. Regular cannabis co-use had a negative impact on tobacco abstinence among younger to middle-aged adults. Addressing cannabis use should be incorporated into standard tobacco treatment to improve cessation outcomes.
