In fact, as many as 1/3 of those who struggle with mental health issues in San Jose, CA. also become involved in substance abuse at some point in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to ease the symptoms of an underlying psychological disorder. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation center is this sort of issue brought to light.
