Many addicted individuals in West Peoria, Illinois who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who struggle with mental health issues in West Peoria, Illinois also take part 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 alleviate the symptoms of an underlying psychological disorder. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug treatment center is this sort of issue uncovered. 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 strong chance of remaining clean and sober and psychologically stable in the future.
