Many people in Duncannon 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 Duncannon also take part in substance abuse at some point in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate in an attempt to alleviate the symptoms of an underlying psychiatric condition. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation facility is this sort of issue brought to light. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive treatment for both disorders so that they have a strong chance of remaining abstinent and psychologically stable in the future.
