Abstract

Cue reactivity theory implies that in relation to drug use, exposure to drug related cues will produce an increased sense of craving for the substance. This study aimed to investigate the effects of exposure to marijuana related cues on marijuana users self reported levels of craving. 59 participants were involved in an online questionnaire containing the Marijuana Craving Questionnaire, the Leeds Dependence Questionnaire and the Becks Depression Inventory. Participants were split in to two groups: group one; no cues ( n = 27; 15 males & 12 females) and group two (n= 32; 22 males & 10 females) who were exposed to marijuana related cues during completion of the Marijuana Craving Questionnaire. A one way MANCOVA was conducted, with participant’s levels of dependence as a covariate. Although the levels of craving across the four factors of the Marijuana Craving Questionnaire (compulsivity, emotionality, expectancy and purposefulness) were slightly higher for group two than for group one the research concluded that there was no statistically significant difference between the self report levels of craving of the two groups; therefore rejecting its hypothesis.
