Many addicted individuals in Toluca, 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 suffer with mental health issues in Toluca also take part in substance abuse at some time in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate in an attempt to relieve the symptoms of an underlying psychiatric issue. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehabilitation center is this sort of issue uncovered. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive treatment for both disorders so that they have a good chance of remaining abstinent and mentally healthy in the future.
