Many addicted individuals in Harrisburg who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who suffer with mental health issues in Harrisburg also become involved in substance abuse at some point in their lives. These dual diagnosis clients often turn to alcohol or drugs to self medicate in an attempt to ease the symptoms of an underlying psychological disorder. Some treatment clients aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehabilitation center is this sort of issue discovered. This in itself 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 stable in the future.
