Many individuals in O Fallon 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 struggle with mental health issues in O Fallon also take part 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 alleviate the symptoms of an underlying psychiatric disorder. Some treatment clients aren't even diagnosed with a psychological condition, and only when they make it to a drug rehabilitation program is this sort of psychological condition brought to light. This alone can help resolve addiction issues and put the individual in a position to receive rehabilitation for both conditions so that they have a good chance of remaining abstinent and mentally stable in the future.
