Injecting drug users (IDUs) account for the largest share of HIV infections in China, Russia, Ukraine, Central Asia, and much of Southeast Asia. Harm reduction measures such as access to clean needles and drug treatment with methadone or buprenorphine have been proven to reduce HIV risk behaviors. Yet law enforcement officials in many countries harass drug users at drug treatment clinics and needle exchange points, confiscate their medications, or arrest them for possession of clean syringes. These police practices help fuel the HIV epidemic by driving drug users away from lifesaving care while doing little to stem drug use.
Globally, illicit drug policy is largely based on two central policy objectives. The first is to reduce the demand for illegal drugs mainly through criminalisation, drug prevention and treatment, and the second is to reduce the supply of illegal drugs primarily through law enforcement initiatives.
