Many people in Bremen who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who suffer with mental health issues in Bremen also become involved in substance abuse at some point in their lives. These dual diagnosis clients often turn to alcohol or drugs to self medicate as a way to relieve the symptoms of an underlying psychological disorder. Some addicts aren't even diagnosed with a psychological condition, and only when they make it to a drug treatment facility is this sort of issue brought to light. This alone can help resolve addiction issues and put the person in a position to receive rehabilitation for both disorders so that they have a strong chance of remaining abstinent and psychologically healthy in the future.
