Thanks Mentalist, for the request. To complete a worthy hub, I will have to do some research on this subject. My guess is yes, especially among teens and young people, however, when you consider alcohol, and all other drugs combined, I'm not so sure. Prescription drugs are definitely the hardest to detect, from an addiction perspective, because they are legal, and often prescribed by doctors. Lets just say they are a much bigger problem than can be proven, but let me see what the authorities say about the comparison stats. Thanks again.
