This study tested the impact of a long-acting form of amphetamine as medication to help control dependent use of the closely allied stimulant, methamphetamine. Prescribed usually for the treatment of pathological sleepiness or attention deficit/hyperactivity disorder, effects of the amphetamine tablets prescribed in the study take several hours longer to emerge than normal amphetamine and last three to six hours longer, giving it a 'smoothing' profile similar to methadone for heroin users; non-rapid onset make it less intensely pleasurable, and longer duration suits it to once-daily administration.
