Many addicted individuals in Oregon who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who suffer with mental health issues in Oregon, Missouri also take part in substance abuse at some point in their lives. These dual diagnosis clients often turn to alcohol or drugs to self medicate in an attempt to relieve the symptoms of an underlying psychological issue. Some addicts aren't even diagnosed with a disorder, and only when they make it to a drug rehab program 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 conditions so that they have a strong chance of remaining abstinent and mentally healthy in the future.
