Many people in Prentice 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 Prentice also become involved in substance abuse at some time in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to ease the symptoms of an underlying psychiatric disorder. Some treatment clients aren't even diagnosed with a disorder, and only when they make it to a drug rehabilitation program 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 get treatment for both conditions so that they have a good chance of remaining abstinent and mentally healthy in the future.
