Many individuals in Highland 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 Highland also take part in substance abuse at some time in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate in an attempt to relieve the symptoms of an underlying psychological issue. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehab center 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 rehabilitation for both disorders so that they have a good chance of remaining abstinent and psychologically healthy in the future.
