Many people in Portland, Texas who find their way to 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 Portland also become involved in substance abuse at some time in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate as a way to relieve the symptoms of an underlying psychological condition. Some addicts aren't even diagnosed with a disorder, and only when they make it to a drug rehabilitation center is this sort of psychological condition brought to light. This in itself can sometimes help resolve addiction issues and put the person in a position to receive treatment for both conditions so that they have a good chance of remaining clean and sober and mentally stable in the future.
