Many individuals in Chester 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 Chester also take part in substance abuse at some point in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to relieve the symptoms of an underlying psychological 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 psychological condition discovered. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive rehabilitation for both disorders so that they have a good chance of remaining clean and sober and psychologically healthy in the future.
