Being diagnosed with HIV/AIDS may set off substance abuse, or risky sexual behavior because of abusing drugs could have caused the individual to contract the disease. People who have HIV/AIDS, either as a result of their drug abuse or as a pre-existing problem before their substance abuse issue, often require treatment services tailored to satisfy their specific demands and challenges. Some of these challenges are physical in nature, due to the fact that drug users with HIV/AIDS almost never care for themselves and take the proper medicines they need to maintain their own health. Consequently, these individuals arrive to rehabilitation in very poor health and this will have to be addressed as a priority whilst dealing with other important issues. In addition to the obvious requirement to deliver medical services whilst in rehabilitation, people with HIV/AIDS also have to address more deeply rooted issues which prompted their drug or alcohol use. Frequently, individuals have circumstances in their lives that happen to be purely environmental which may have caused them to use drugs or alcohol, such as oppressive circumstances within their lives or detrimental relationships. These are the issues which rehabilitation professionals will focus on as part of HIV/AIDS rehab services.
