Being diagnosed with HIV/AIDS may trigger substance abuse, or risky sexual conduct due to drug use could possibly have caused the person to contract the illness. Individuals who have HIV/AIDS, either because of their substance abuse or as a pre-existing problem prior to their substance abuse problem, often require rehabilitation services tailored to satisfy their particular demands and problems. Some challenges are physical in nature, because of the fact that drug users with HIV/AIDS rarely look after themselves and take the appropriate medicines they need to maintain their own health. As a result, they arrive to rehabilitation in very poor health and this will have to be handled as a priority whilst dealing with other important issues. Aside from the obvious requirement to offer medical services while in rehabilitation, individuals with HIV/AIDS also have to tackle deeper issues which brought about their drug or alcohol use. Often, individuals have situations in their lives that are strictly environmental which may have triggered them to use drugs or alcohol, like oppressive circumstances in their lives or detrimental relationships. These are the concerns which rehabilitation counselors will give attention to as part of HIV/AIDS treatment services.
