Many people in Catherine, Alabama 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 struggle with mental health issues in Catherine also take part in substance abuse at some time in their lives. These dual diagnosis clients often turn to alcohol or drugs to self medicate as a way to alleviate the symptoms of an underlying psychological issue. 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 psychological condition uncovered. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive treatment for both conditions so that they have a strong chance of remaining clean and sober and psychologically stable in the future.
