Marijuana Withdrawal Symptom Checklist

The MWSC is a 10-item self-administered questionnaire developed by Budney et al. (1999). Each of the 10 items is a withdrawal symptom that is rated on a 4-point scale as follows: 0 = not at all; 1 = mild; 2 = moderate; 3 = severe. The 10 withdrawal symptoms include: 1) craving, 2) irritability, 3) nervousness, 4) depression, 5) anger, 6) restlessness, 7) sleep problems, 8) decreased appetite, 9) strange dreams, and 10) headaches. Symptoms will be evaluated individually and by computing a total withdrawal discomfort score (WDS) that is the sum of the individual item scores.
