Abstract

OBJECTIVE:

Identifying factors that moderate subjective response to stimulants is important for understanding individuals at risk for abusing these drugs. Some research suggests that Asians may respond differently to stimulants than other races, but controlled human laboratory research of stimulant administration effects in Asians is scant.

METHODS:

In this double-blind counterbalanced within-subject study, healthy stimulant-naïve participants (N = 65; 55% Asian; 63% female; age 18-35) received a single dose of 20-mg oral d-amphetamine or placebo on separate days. At each testing day, subjective measures of abuse liability and cardiovascular assessments were administered at repeated intervals before and after drug administration over a 4-hour period.

RESULTS:

Asians (vs. Whites) demonstrated greater d-amphetamine-induced increases in diastolic blood pressure and ratings of 'Feel High' and 'Like Drug'.

CONCLUSIONS:

Asian and White healthy young adults may differ in certain subjective and cardiovascular responses to acute doses of d-amphetamine. Such individual differences could help explain between-person differences in abuse potential of d-amphetamine and other stimulants.
