Background: Understanding motivations behind non-medical use of prescription stimulants (NMUPS) is important to prevent such use.
Methods: Adult participants from St. Louis, MO, who endorsed NMUPS on 5 or more days in the past 12 months (n=60) were asked about their motivations for use. Associations between motives for use and patterns of non-medical use in the past 12 months were assessed using multivariable logistic regression, controlling for demographic factors and non-medical use of other prescription drugs.
Results: On average, 5.5 different motives for stimulant use were endorsed. Compared to those who only used someone else's stimulants, adults who only used stimulants other than prescribed were less likely to endorse use "to get high" (aOR=0.48, 95%CI 0.26-0.90) and more likely to endorse use "to function" (aOR=1.97, 95%CI 1.04-3.75); adults who were engaged in both patterns of NMUPS were more likely to endorse use "to function" (aOR=4.12, 95%CI 1.56-10.88) and "to modify the effects of other drugs" (aOR=2.29, 95%CI 1.13-4.61).
Conclusion: Although using stimulants for performance enhancement is common, most people who used diverted stimulants reported using stimulants to get high. Prevention and harm reduction strategies should consider these differences.
