Many addicted individuals in Carnegie who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who struggle with mental health issues in Carnegie also become involved in substance abuse at some point in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to alleviate the symptoms of an underlying psychiatric issue. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehab program is this sort of psychological condition uncovered. This alone can sometimes help resolve addiction issues and put the individual in a position to get rehabilitation for both disorders so that they have a good chance of remaining abstinent and psychologically healthy in the future.
