Frankly, it is more common than one would think and a lot of people currently in drug and alcohol treatment facilities in Waterford, California may have psychological disorders which are often undiagnosed. Rehabilitation experts at proven drug and alcohol treatment centers in Waterford know how to spot persons with co-occurring mental health and drug and alcohol abuse issues so that these two concerns can be handled simultaneously while the individual is in rehab.
