Being diagnosed with HIV/AIDS may trigger drug use, or risky sexual behavior as a result of drug use could have caused the individual to contract the disease. Individuals who have HIV/AIDS, either because of their substance abuse or as a pre-existing problem prior to their substance abuse issue, typically require rehab services tailor-made in order to meet their particular demands and challenges. Some 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 medications they need to maintain their health. Therefore, they arrive to treatment in very poor health and this will have to be addressed as a priority while dealing with other important issues. In addition to the obvious necessity to supply medical services while in rehab, individuals with HIV/AIDS also have to deal with more deeply rooted issues which prompted their alcohol or drug use. Frequently, people have conditions in their lives that happen to be purely environmental which may have caused them to turn to alcohol or drugs, such as oppressive circumstances within their lives or negative relationships. These are the issues which rehabilitation professionals will target as part of HIV/AIDS rehabilitation services.
