Many individuals in Mc Lean, IL. who find their way to 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 Mc Lean, IL. also take part in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to drugs or alcohol to self medicate in an attempt to ease 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 rehabilitation program is this sort of psychological condition discovered.
