Summary
Approximately 19% of past-year psychostimulant users developed dependence, with females being 2.6 times more likely than males. Early use, multiple drug use, and early smoking onset increase dependence risk.
Area of Science:
- Psychiatry
- Addiction Medicine
- Public Health
Background:
- Nonmedical psychostimulant use is a significant public health concern.
- Understanding the factors contributing to psychostimulant dependence is crucial for prevention and treatment.
Purpose of the Study:
- To determine the prevalence of psychostimulant dependence among nonmedical users.
- To identify characteristics associated with the development of psychostimulant dependence.
Main Methods:
- Analysis of data from the 1995-1998 National Household Surveys on Drug Abuse.
- Inclusion of 1047 individuals aged 12+ reporting past-year nonmedical stimulant use.
- Utilized multinomial logistic regression to identify risk factors for dependence.
Main Results:
- 19% of past-year stimulant users met criteria for dependence; 16% reported 1-2 dependence problems.
- Female users were 2.6 times more likely than males to develop dependence.
- Early stimulant use onset, polysubstance use, and adolescent-onset daily smoking were associated with increased dependence risk. The Western US region showed higher prevalence and dependence rates.
Conclusions:
- Significant gender disparities exist in psychostimulant dependence development.
- Further research is needed to explore cultural and perceptual factors influencing drug choice in females.
- Understanding these factors can inform targeted interventions for psychostimulant use disorder.
