Many people in Tortilla Flat, Arizona who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who suffer with mental health issues in Tortilla Flat, Arizona also take part in substance abuse at some point in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate as a way to ease the symptoms of an underlying psychiatric condition. 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 uncovered. This in itself can help resolve addiction issues and put the individual in a position to get rehabilitation for both disorders so that they have a good chance of remaining clean and sober and mentally healthy in the future.
