Many people in Altamont who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who suffer with mental health issues in Altamont also become involved in substance abuse at some time in their lives. These dual diagnosis clients frequently turn to drugs or alcohol to self medicate as a way to alleviate the symptoms of an underlying psychological disorder. Some addicted individuals aren't even diagnosed with a disorder, and only when they make it to a drug rehabilitation program is this sort of psychological condition brought to light. This in itself can sometimes help resolve addiction issues and put the person in a position to receive rehabilitation for both conditions so that they have a strong chance of remaining abstinent and psychologically healthy in the future.
