Many addicted individuals in Lancaster, Pennsylvania 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 Lancaster also take part in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to drugs or alcohol to self medicate in an attempt to alleviate the symptoms of an underlying psychiatric disorder. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehab facility is this sort of psychological condition uncovered. 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 good chance of remaining abstinent and psychologically healthy in the future.
