Many individuals in Hamburg who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who struggle with mental health issues in Hamburg also take part in substance abuse at some point in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate as a way to alleviate the symptoms of an underlying psychiatric condition. Some addicts aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehab program is this sort of issue brought to light. This alone can sometimes help resolve addiction issues and put the individual in a position to receive treatment for both disorders so that they have a good chance of remaining abstinent and psychologically healthy in the future.
