Being diagnosed with HIV/AIDS may set off drug or alcohol use, or dangerous sexual conduct due to abusing drugs could have caused the person to contract the disease. Individuals who have HIV/AIDS, either due to their substance abuse or as a pre-existing problem prior to their drug use problem, often require rehab services tailored to meet their specific demands and challenges. A few of these challenges are physical in nature, due to the fact that substance abusers with HIV/AIDS very rarely take care of themselves and take the appropriate medicines they need to preserve their own health. Consequently, these individuals arrive to rehabilitation in very poor health and this will have to be handled as a priority whilst dealing with other important issues. Apart from the obvious necessity to deliver medical services while in rehab, people who have HIV/AIDS must also deal with more deeply rooted issues which prompted their drug or alcohol use. Frequently, people have conditions in their lives that are purely environmental which may have caused them to use alcohol or drugs, including oppressive circumstances within their lives or negative relationships. These are the issues which treatment professionals will focus on as part of HIV/AIDS treatment services.
