US Presidents who smoked pot

Seven early US presidents were pot smokers: George Washington, Thomas Jefferson, James Madison, James Monroe, Andrew Jackson, Zachary Taylor and Franklin Pierce And a few from modernity. Carter, Reagan, Bush, Clinton, Chimpy and Obama. God bless the war on drugs. This does beg the question: How does Supreme Asshole and strick constitutionalist Scalia manage to corrupt his satanic world view to come down against pot.
