Responding to global stimulant use: challenges and opportunities

Area of Science:

• Public Health
• Epidemiology
• Substance Use Research

Background:

• Stimulant use, particularly cocaine and amphetamines, poses a significant global health challenge.
• Understanding the prevalence, associated harms, and effectiveness of interventions is crucial for public health strategies.

Purpose of the Study:

• To synthesize global data on stimulant use prevalence, harms, and interventions.
• To estimate the impact of cocaine and amphetamine use on mortality, suicidality, and blood-borne virus incidence.

Main Methods:

• Global literature review and data synthesis.
• Epidemiological modeling to estimate the effects of stimulant use on key health outcomes.

Main Results:

• Estimated global prevalence of cocaine use at 0.4% and amphetamine use at 0.7%.
• Stimulant use is associated with elevated mortality, increased HIV and Hepatitis C incidence, poor mental health, and cardiovascular risks.
• Dependence rates were 16% for cocaine users and 11% for amphetamine users.

Conclusions:

• Current pharmacotherapies are ineffective for reducing stimulant use; psychosocial interventions show limited effects, except for contingency management.
• Generic public health approaches require tailoring to mitigate stimulant-specific harms.
• Substantial investment is critical for developing effective stimulant use interventions.
