Many people in Gleason 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 Gleason 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 psychological condition. Some treatment clients 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 help resolve addiction issues and put the individual in a position to receive rehabilitation for both disorders so that they have a strong chance of remaining clean and sober and psychologically stable in the future.
