Many individuals in Durham, California 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 Durham, California also become involved 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 ease the symptoms of an underlying psychological disorder. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug treatment program is this sort of psychological condition uncovered. This in itself 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 clean and sober and mentally stable in the future.
