Many individuals in Hamilton 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 Hamilton also take part in substance abuse at some point in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate as a way to ease the symptoms of an underlying psychological issue. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they make it to a drug rehabilitation program is this sort of issue discovered. This in itself can help resolve addiction issues and put the person in a position to get treatment for both disorders so that they have a strong chance of remaining abstinent and psychologically healthy in the future.
