Many addicted individuals in Millersville, PA. 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 Millersville also become involved 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 addicted individuals aren't even diagnosed with a disorder, and only when they make it to a drug rehabilitation program is this sort of issue discovered. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive rehabilitation for both conditions so that they have a good chance of remaining abstinent and psychologically stable in the future.
