Many individuals in Nassau, New York who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who struggle with mental health issues in Nassau, New York 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 alleviate the symptoms of an underlying psychiatric condition. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation center is this sort of psychological condition uncovered. This alone can help resolve addiction issues and put the individual in a position to receive treatment for both conditions so that they have a good chance of remaining clean and sober and mentally stable in the future.
