Drug use among men who have sex with men (MSM) in Asia is an established trend.
Evidence shows that using club drugs, such as cocaine, ecstasy, gamma hydroxy butyrate (GHB), ketamine and methamphetamine, taking erectile dysfunction medications1, 2, 3and binge drinking4 place a subgroup of Asian MSM at high risk for HIV infection.
These findings link to international evidence showing substance use among MSM is associated with increased sexual risk-taking.5
Parallel to the increase in HIV prevalence among Thai MSM is an increase in recreational drug use.
The use of amphetamine-type stimulants increased from 3.6% in 2003 to 17.5% in 2005, and to 20.8% in 2007.8
These findings are of concern for HIV prevention as there is a strong predictor between amphetamine-type stimulant use and HIV seroconversion among MSM.13
However, there are other major obstacles to HIV prevention among MSM and transgender people who use drugs in Asia and the Pacific:
Criminalisation of drug use and MSM and transgender people
Given the legal restrictions on drug use and in some cases the criminalisation of male-to-male sex in Asia and the Pacific, multiple challenges remain in enrolling MSM and transgender people who use drugs into HIV testing, treatment and care programs.
Overlapping vulnerabilities to HIV
However, it is particularly challenging to reach marginalised MSM sex workers who remain hidden for legal reasons.
An understanding of the individual, social, and societal effects of drug use among MSM and transgender people is needed so that evidence-based interventions can be developed to reduce HIV transmission among these subgroups.
Gay social media and social networking applications may be useful in reaching some of these populations.
Lack of evidence-based interventions for MSM and transgender people who use drugs
Although there is a range of evidence-based HIV prevention interventions available for MSM, for transgender people and for people who use drugs, there is a lack of documentation of evidence-based interventions specifically for MSM and TG who use drugs in the Asian context.
Interventions for MSM and transgender people who use drugs and alcohol must not only be culturally congruent, they must also be comprehensive and focus on both prevention and treatment.
An understanding of the risks associated with drug use, especially amphetamine-type stimulants, need to be integrated into current prevention messages targeting MSM and transgender people.
Lack of data on MSM and transgender people who use drugs
Despite data from a cohort study that demonstrated the association between illicit drug use and HIV incidence in Thailand,19 drug use among MSM in Asia remains under-studied.
Drug-use patterns and HIV-related risks among transgender people are even more poorly understood because such studies are extremely rare, despite a recent systematic review and meta-analysis of global studies showing that transgender people bear a much higher HIV burden (50-fold higher) than the general adult population.20
New, innovative ways to recruit drug-using MSM and transgender people21 need empirical testing in Asian populations.
New data collection modalities, such as Internet/smartphone surveys or automated telephone interviewing systems may offer alternatives to the collection of sensitive data on drug use and sexual behaviours.
