While I have no serious objections to your comments, I don't
think the scoring makes sense.  Also, you seem to give less
credit to people who drink moderately to those who smoke pot 
regularly.  I am someone who I think has a healthy attitude 
toward drugs, who drinks wine sometimes not at all and sometimes
daily and two or three times a year I might even like to get
drunk (not hammered), who does not smoke cigarettes or pot, 
there is no point-value I can assign myself to and if there
were I think it would be pretty low on your ranking.
