Many people in Defiance 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 Defiance also take part in substance abuse at some point 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 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 issue brought to light. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive treatment for both disorders so that they have a strong chance of remaining abstinent and mentally healthy in the future.
