|Study Completion Date :||July 2011|
|Placebo Comparator: Placebo||
Placebo administration will be started on day 2 and stopped on day 5. Methylsulonylmethane (MSM) will serve as a placebo for MA.
Other Name: Methylsulonylmethane (MSM)
|Active Comparator: N-Acetylcysteine (NAC) 1800 mg||
Study medication (NAC 1800 mg) will be started on day 2 and stopped on day 5.
Other Name: NAC
|Active Comparator: N-Acetylcysteine (NAC) 3600 mg||
Study medication (NAC 3600 mg) will be started on day 2 and stopped on day 5.
Other Name: NAC
- The effects of treatment with NAC (placebo, 1800 and 3600 mg daily), compared to treatment with placebo, on cue- and MA-induced craving and subjective effects in MA-dependent human volunteers.On days 3-5, participants will take part in active cues and neutral cues. On days 4 and 5, they will make choices to receive MA/placebo in a self-administration paradigm. Participants will also rate craving, desire, and would take MA if available on a 0-100 mm visual analogue scale.
- The effects of treatment with NAC (placebo, 1800 and 3600 mg daily), compared to treatment with placebo, on the reinforcing effects of MA by measuring MA self-administration in MA-dependent human volunteers.On days 4 and 5, participants will make choices to receive MA/placebo in a self-administration paradigm. Any alterations in the reinforcing effects of MA associated with NAC treatment will be evident as changes in the number of choices made for MA.
