Many addicted individuals in Antoine who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who struggle with mental health issues in Antoine also become involved 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 relieve the symptoms of an underlying psychiatric issue. Some addicts aren't even diagnosed with a disorder, and only when they make it to a drug rehabilitation facility is this sort of psychological condition brought to light. This in itself can help resolve addiction issues and put the individual in a position to receive rehabilitation for both conditions so that they have a strong chance of remaining abstinent and psychologically stable in the future.
