Many individuals in Gravel Switch who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who suffer with mental health issues in Gravel Switch also become involved in substance abuse at some time in their lives. These dual diagnosis clients frequently turn to drugs or alcohol to self medicate as a way to ease the symptoms of an underlying psychiatric disorder. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehab center is this sort of psychological condition uncovered. This alone can help resolve addiction issues and put the person in a position to get rehabilitation for both conditions so that they have a strong chance of remaining clean and sober and psychologically healthy in the future.
