[QUOTE="Sara PA, post: 154325, member: 1498"] Vyvanse is a Schedule II Controlled Drug just like all the other amphetamines. The potential for abuse and addiction is there. It may be less in some circumstance but certainly it hasn't been removed. From the prescribing information: [I]Human Studies In a human abuse liability study, when equivalent oral doses of 100 mg lisdexamfetamine dimesylate and 40 mg immediate release d-amphetamine sulfate were administered to individuals with a history of drug abuse, lisdexamfetamine dimesylate 100 mg produced subjective responses on a scale of 'Drug Liking Effects' 'Amphetamine Effects', and 'Stimulant Effects' that were significantly less than d-amphetamine immediate release 40 mg. However, oral administration of 150 mg lisdexamfetamine dimesylate produced increases in positive subjective responses on these scales that were statistically indistinguishable from the positive subjective responses produced by 40 mg of oral immediate-release d-amphetamine and 200 mg of diethylpropion (C-IV). Intravenous administration of 50 mg lisdexamfetamine dimesylate to individuals with a history of drug abuse produced positive subjective responses on scales measuring 'Drug Liking', 'Euphoria', 'Amphetamine Effects', and 'Benzedrine Effects' that were greater than placebo but less than those produced by an equivalent dose (20 mg) of intravenous d-amphetamine.[/I] [/QUOTE]
