Many addicted individuals in Marquette 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 Marquette, Iowa 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 in an attempt to relieve the symptoms of an underlying psychological condition. Some addicts aren't even diagnosed with a psychological condition, and only when they make it to a drug treatment center is this sort of psychological condition brought to light. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive rehabilitation for both conditions so that they have a strong chance of remaining clean and sober and mentally healthy in the future.
