No offence guys, and I'm not trying to undermine your movement, since I fundamentally agree with it, but you have to know how this looks to an outsider: A: "Legalize weed! It's not bad for you!" B: "But there is conflicting evidence, some say it might be bad for you!" A: "No, it's not bad for you at all!" B: "But these studies!" Provides links A: "Well, whatever, I know it's not bad for you, despite studies that say otherwise." I think that approach is going to ultimately slow the progress you make. Try, instead, to be less convinced and more convincing. Seriously, there are scientific studies that claim that cannabis is not as harmful as the government says it is. Start to get to know those studies and use them. Just saying "You're wrong, because I know better than you and I don't have to explain why," or "I use this, therefore I know more about it than everyone else," just doesn't get you anywhere in an argument.
