If you feel that way about alcohol, why aren’t you fighting to make it illegal?
Just because the government legalizes something doesn't make it good public policy. He is a link to a study showing the economic and societal costs of alcohol and drug abuse. http://www.nida.nih.gov/EconomicCosts/Index.html If after reading the link, you think its still GOOD public policy to legalize marijuana, let me know why other than a generic "we can make better use of resources."
