I'd like to clarify, concerning the 16%, the hazardous drinking behaviour, that has not necessarily reached the threshold of substance abuse nor of alcoholism or other drug dependency. Those who work in the public health field will recognize hazardous drinking behaviour as any regular consumption of more than two drinks per day on average for males, and more than one drink per day on average for females. It's a fairly low threshold as a possible warning sign.
