Many individuals in French Village 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 suffer with mental health issues in French Village, Missouri also become involved in substance abuse at some time in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate in an attempt to relieve the symptoms of an underlying psychological condition. Some addicts aren't even diagnosed with a psychological condition, and only when they make it to a drug treatment facility is this sort of psychological condition uncovered. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive treatment for both conditions so that they have a strong chance of remaining abstinent and mentally healthy in the future.
