简要总结
The purpose of this study is to examine whether individual differences in acute responses to drugs co-vary across three drugs from different drug classes: alcohol, amphetamine and delta-9-tetrahydrocannabinol (THC). The investigators hypothesize that individuals who experience greater rewarding effects from one drug will also experience more rewarding effects from the other drugs.
详细描述
Here, the investigators aim to investigate whether individuals exhibit similar responses to three different drugs from different classes. This study used a within-subjects design (total N = 24). All subjects received alcohol, amphetamine and delta-9-tetrahydrocannabinol (THC) in a double-blind, double-dummy fashion. Subjects completed six sessions wherein they received either alcohol, amphetamine, or THC, or corresponding placebos, on separate days. Subjects completed questionnaires about mood, general drug effects, and specific drug effects.

结局指标
主要结局
Change in General Drug Effects (Drug Effects Questionnaire) at 90 Minutes After Drink Administration
时间窗: Measured 15 minutes prior to capsule administration and 90 minutes after drink administration.
Drug effects will be measured using the Drug Effects Questionnaire (Fischman \& Foltin, 1991). The DEQ included 5 subscales; feeling, liking, and disliking the drug effect, feeling high, and wanting more of the drug. Each subscale ranged from 1(Not at all) to 100(Very much). The change in DFQ was assessed by the difference in measurements between baseline and 90 minutes after drink administration. Baseline was measure 15 minutes prior to capsule administration.
Change in Specific Drug Effects (Addiction Research Center Inventory) at 90 Minutes After Drink Administration
时间窗: Measured 15 minutes prior to capsule administration and 90 minutes after drink administration
Specific drug effects will be measured using the Addiction Research Center Inventory (Martin et al. 1971). The ARCI measures effects specific to drug classes, including the effects of AMP-like drugs (A scale, 0 to 11), morphine and benzedrine like drugs (MBG scale, 0 to 14), lysergic acid-like drugs (LSD scale, 0 to 14), benzedrine-like drugs (BG scale, 0 to 13), pentobarbital-chlorpromazine and ALC-like drugs (PCAG scale, 0 to 15), and cannabis-like drugs (M scale, 0 to 12). We used this questionnaire as a manipulation check to ensure that the drugs produced their typical drug-specific effects in this study. For example, zero value of A sacle would be minimum report of amphetamine-like drug effects, and 11 would be maximum report of amphetamine-like effects. The change in ARCI was assessed by the difference in measurements between baseline and 90 minutes after drink administration. Baseline was measure 15 minutes prior to capsule administration.
Change in Specific Drug Effects (Addiction Research Center Inventory) at 120 Minutes After Drink Administration
时间窗: Measured 15 minutes prior to capsule administration and 120 minutes after drink administration
Specific drug effects will be measured using the Addiction Research Center Inventory (Martin et al. 1971). The ARCI measures effects specific to drug classes, including the effects of AMP-like drugs (A scale, 0 to 11), morphine and benzedrine like drugs (MBG scale, 0 to 14), lysergic acid-like drugs (LSD scale, 0 to 14), benzedrine-like drugs (BG scale, 0 to 13), pentobarbital-chlorpromazine and ALC-like drugs (PCAG scale, 0 to 15), and cannabis-like drugs (M scale, 0 to 12). We used this questionnaire as a manipulation check to ensure that the drugs produced their typical drug-specific effects in this study. For example, zero value of A sacle would be minimum report of amphetamine-like drug effects, and 11 would be maximum report of amphetamine-like effects.The change in ARCI was assessed by the difference in measurements between baseline and 120 minutes after drink administration. Baseline was measure 15 minutes prior to capsule administration.
