The Craving and Mood Questionnaire (CMQ) consists of five items that were rated on a scale of 0–100 and were combined to form a marijuana craving scale. The five items (modified to measure craving for marijuana) are: ‘I crave marijuana right now’, ‘I have an urge for marijuana’, ‘I have a desire for marijuana right now,’ ‘if it were possible, I would smoke marijuana now’ and ‘all I want right now is marijuana’.
