Many individuals in Eugene, Oregon 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 Eugene also become involved in substance abuse at some time in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to alleviate the symptoms of an underlying psychological condition. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug treatment program is this sort of psychological condition brought to light. This alone can help resolve addiction issues and put the person in a position to receive rehabilitation for both conditions so that they have a good chance of remaining abstinent and mentally stable in the future.
