Background: The majority of cannabis smokers who quit do so without formal treatment, suggesting that

motivations to quit are an important part of cessation process. However, little is known about how motivations

relate to successful quitting.

Method: A convenience sample of 385 non-treatment-seeking adult cannabis smokers (58% male, age 16–

64 years at start of quit attempt) who made a “serious” (self-defined) quit attempt without formal treatment

while not in a controlled environment were administered the 176-item Marijuana Quit Questionnaire (MJQQ)

to assess their motivations to quit and outcome of the quit attempt. Exploratory factor analysis was performed

to identify significant motivational factors. Subgroup comparisons used t-tests and ANOVA. Cox proportional

hazard regression and the General Linear Model were performed to evaluate the influence of motivational factors,

gender, and age on relapse status at time of interview and risk of relapse over time, with time between

quit attempt and interview as a covariate.

Results: Exploratory factor analysis identified 6 motivational factors with eigenvalues >1 which accounted for

58.4% of the total variance: self-image and self-control, health concerns, interpersonal relationship concerns,

legal concerns, social acceptability concerns, and self-efficacy.Womenwere more likely than men to bemotivated

by self-image/self-control, health concerns, and social acceptability concerns. Older individuals were more

likely to be motivated by health concerns. At the time of interview, 339 subjects had relapsed. Self-image and

self-control, health concerns, interpersonal relationship concerns, and social acceptability concerns were associatedwith

greater likelihood of abstinence at the study interview. Legal concerns and social acceptability concerns

were associated with significantly lower hazard ratios (0.88, 0.83) for relapse during the abstinent period.

Conclusion: These findings show gender and age differences in motivations to quit cannabis smoking and that

adult cannabis smokers have motivations to quite similar to those of adolescent cannabis smokers and of adults

who quit alcohol and tobacco use without formal treatment. The findings suggest areas of focus to improve

secondary prevention and psychosocial treatment efforts.
