The influence of cannabis motives on alcohol, cannabis, and tobacco use among treatment-seeking cigarette smokers

Abstract

Objectives The present study evaluated the effects of cannabis motives on multi-substance use in an effort to examine the incremental validity of cannabis motives with respect to substance use outcomes. Methods Participants were 167 treatment-seeking smokers (41.92% female; Mage = 28.74; SD = 11.88) who reported smoking an average of 10 or more cigarettes daily for at least one year. Results Structural equation modeling was used to examine the association between cannabis motives and two dependent variables each for alcohol (drinking frequency and alcohol problems), cannabis (cannabis use frequency and cannabis problems), and tobacco (average cigarettes per day and nicotine dependence). Findings indicated that conformity motives were linked with increases in alcohol problems and cannabis problems. Enhancement motives were associated with increased cannabis use and cannabis problems. Coping motives were linked with increased cannabis use and cannabis problems. Contrary to expectations, expansion motives were associated with reductions in the number of cigarettes smoked per day. Also, results supported expectations that the observed effects due to cannabis motives were unique from shared variance with theoretically relevant covariates. Conclusions The present findings supported predictions that cannabis motives would evince effects on the use of multiple substances over and above theoretically relevant variables. However, results indicate that the relationship between cannabis motives and multi-substance use is complex, and therefore, additional research is warranted to better understand substance use intervention.

Desarrollo y validación de la versión breve del cuestionario de motivos de consumo de marihuana (MMM SF)

“…Estudios transversales con el MMM (Simons et al, 1998) han encontrado que los motivos de animación se relacionan con el uso de cannabis (Buckner, 2013;Foster, Allan, Zvolensky, y Schmidt, 2014;Simons, Simons, y Spelman, 2016), y también con los problemas derivados del consumo de cannabis (Simons, Gaher, Correia, Hansen, y Christopher, 2005). Los motivos de afrontamiento se han relacionado con el consumo de cannabis, problemas derivados del consumo de cannabis (Buckner, 2013;Buckner y Zvolensky, 2014;Buckner, Zvolensky, y Schmidt, 2012;Foster et al, 2014;Simons et al, 2016) y dependencia de cannabis (Moitra, Christopher, Anderson, y Stein, 2015). Los motivos de expansión se han relacionado con la frecuencia de consumo de cannabis y la dependencia de cannabis en mujeres con síntomas de trastorno límite de la personalidad (Chabrol et al, 2005), y también con los problemas derivados del consumo en una muestra de consumidores actuales de cannabis (Buckner y Zvolensky, 2014).…”

Por último, se ha hallado una relación negativa entre los motivos sociales y de conformidad con la frecuencia de consumo de cannabis (Buckner, 2013;Buckner y Zvolensky, 2014), y tan solo una relación positiva entre los motivos de conformidad y los problemas derivados del consumo de cannabis (Buckner et al, 2012;Foster et al, 2014).…”

Cannabis Motives and Quitting Tobacco

“…A small but growing body of literature has examined the cross-substance links between cannabis and tobacco 8,9 . This work has included examinations from a motivational framework, and indicates that among tobacco users, cannabis motives are linked with increased quantity and frequency of cannabis use 8,10 .…”

“…Moreover, explorations of individual characteristics show that anxiety sensitivity moderates the effect of enhancement motives on cannabis use among daily smokers 8 . Further, specific cannabis motives have been linked with use: coping motives are associated with negative emotional symptoms, whereas enhancement motives are linked with positive affect 11 and with the use of alcohol and tobacco 9 . Thus, cannabis motives contributed unique variance to non-cannabis substance use including nicotine dependence and the number of cigarettes smoked per day 9 .…”
