HIV is being spread among drug abusers by means other than needle sharing. Drug addiction leads people to engage in risky behaviors (e.g. using sex to procure drugs or money) and drug use impairs people’s judgment and lowers their inhibitions, which can lead to impulsive and unsafe behaviors. Therefore, effective drug abuse treatment is also HIV prevention. Indeed, the integration of HIV risk-reduction interventions into drug abuse treatment is imperative.
As a result of scientific research, we know that addiction is a disease that affects both brain and behavior.
