Many individuals in Trilla who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who struggle with mental health issues in Trilla also become involved in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to drugs or alcohol to self medicate as a way to alleviate the symptoms of an underlying psychological issue. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they make it to a drug rehab facility is this sort of psychological condition brought to light. This alone can sometimes help resolve addiction issues and put the person 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.
