Many individuals in South Wales 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 South Wales also become involved 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 ease the symptoms of an underlying psychological disorder. Some addicts aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug treatment facility is this sort of issue uncovered. This alone 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 abstinent and psychologically stable in the future.
