I would take issue with this part
>>The problem with drugs is that only about 12% of the population will have a problem with them. It's a genetic thing
A cool study was done where rats were given the choice of drinking either a cocaine solution or a nutrient solution. Once they had learned which was which, they *never* drank from the nutrient solution until they were dead.
Addictive drugs give anyone's body an "ooh, that's nice!" signal. And I've never heard of any studies showing that there are people (because of their genetics ) who are immuned to addiction effects. (Course, it would be a pretty destructive study to run! Something the Nazis might have done, had addiction been a big issue in the '30s.)
