Why don't you take a stab at it and suggest some non-substance abuse felonies that I and millions of others like me could be guilty of.
from CDC web site:
Sixty-two percent of Americans ages 18 and over have drank alcohol in the past year. (2000)
Thirty-two percent of current drinkers had five or more drinks on the same occasion at least once in the past year.
Sixty-one percent of men 18-24 years and 42 percent of women had 5 or more drinks on the same occasion.
So if I do the math:
68% have not gotten to the illegal blood alcohol level, in the past year.
38% have not even had one drink, in the past year.
61% off young people have gotten drunk at some time in their lives, but there is no crime if they don't drive.
