Many addicted individuals in Brooklyn 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 struggle with mental health issues in Brooklyn also take part in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate in an attempt to ease the symptoms of an underlying psychiatric disorder. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug treatment center is this sort of issue uncovered. This in itself can sometimes help resolve addiction issues and put the individual in a position to get treatment for both disorders so that they have a good chance of remaining clean and sober and psychologically stable in the future.
