Many individuals in Harborcreek 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 struggle with mental health issues in Harborcreek 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 as a way to ease the symptoms of an underlying psychiatric condition. 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 discovered. This in itself can help resolve addiction issues and put the person in a position to get rehabilitation for both conditions so that they have a good chance of remaining clean and sober and psychologically stable in the future.
