Many people in Highland, California 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 Highland also take part in substance abuse at some time in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate as a way 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 treatment center is this sort of issue brought to light. This in itself can help resolve addiction issues and put the person in a position to get rehabilitation for both conditions so that they have a strong chance of remaining clean and sober and mentally healthy in the future.
