Many people in North Zulch 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 North Zulch also take part in substance abuse at some time in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate as a way to alleviate the symptoms of an underlying psychological condition. Some addicts aren't even diagnosed with a disorder, and only when they make it to a drug rehab center is this sort of psychological condition brought to light. This in itself can help resolve addiction issues and put the individual in a position to get rehabilitation for both conditions so that they have a strong chance of remaining abstinent and psychologically healthy in the future.
