Many individuals in Mercer who end up in 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 Mercer, Pennsylvania also become involved in substance abuse at some time in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate in an attempt to ease the symptoms of an underlying psychological disorder. Some addicts aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation program is this sort of issue discovered. This alone can sometimes help resolve addiction issues and put the person in a position to get rehabilitation for both conditions so that they have a good chance of remaining abstinent and mentally stable in the future.
