This is one of the best researched sites on the net. A tactic I use is to find the most adamant, loud mouth prohibitionist and ask them whether they are well informed on marijuana prohibition. When they say yes, lean back and say "Fine, then tell us about the decorticator." When they can't you have them by their balls. I beat a judge this way and really made him think again about his position. This site will give you most of the historical ammo you need.

Pot cures cancer and the government has known for over thirty years. So much for marijuana not being medicine.

We recently had this same discussion on a site in Nevadda where we shut the prohibitionists down, hard. Worth the read to see how their arguements were handled.

Good luck!
