Many individuals in Dunnegan 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 struggle with mental health issues in Dunnegan also take part in substance abuse at some point in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate as a way to ease 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 rehabilitation program is this sort of issue brought to light. This alone can sometimes help resolve addiction issues and put the individual in a position to get treatment for both disorders so that they have a good chance of remaining abstinent and mentally healthy in the future.
