In fact, as many as 1/3 of those who suffer with mental health issues in Fontana, California 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 as a way to relieve the symptoms of an underlying psychological condition.
