"You claim them as a credible source on one hand, and discredit them on the other to suit your belief. "
Incorrect. People who are able to think critically often point to instances in which their arguments have been successfully supported before. That does not indicate that those who successfully supported opinions I share are automatically in agreement with me on any other topics. In this instance, founding fathers supported and successfully argued in favor of personal liberties, as do I.
Now, the logic for the legalization of 'substances which harm humans' is manyfold and has been stated repeatedly on this thread without any logical refutation from you or Zed, whatsoever. Try to keep up as I argue in favor of MJ legalization:
1) Who the fuck are you, or anyone else, to judge what is sufficiently harmful for me to injest or not? *Doctors* don't know the full extent of the effects of drugs they prescribe. Yet, they do so because they believe, based on previously gathered evidence and study, that the benefits outweigh the costs. In the case of recreational mary jane, I, as a responsible adult, have made the decision that the benefits outweigh the costs, for me, which is my right as a free man. You don't have to smoke up if you don't want to, and you don't get to decide whether I get to or not because it does not affect you as long as I'm in my house. *Flintstone Vitamins* are more harmful than MJ. Ask your doctor. I don't speak for you; you definitely don't speak for me.
2) We know, as history and current events have shown, that violating personal liberties through attempting to ban certain recreational substances in an unnecessary way leads to the formation of black markets in which the context for competition is violence. Violent prison gangs. Violent transport and distribution gangs. People die. MJ is illegal, yet, the black market persists because people are willing to exercise their personal liberties and criminal gangs are willing to satisfy and profit from that legitimate demand in an illegitimate way. Other than your assertion that 'it makes people dumb', all other societal ills for which some (you?) claim MJ is to blame are actually caused by the criminal gangs who take over production and transportation. Legalize it, and production and distribution are taken over by legitimate, nonviolent, taxable organizations. We're left with 'it makes people dumb'.
3) 'It makes people dumb' or 'It's harmful' refutation. There are lots of things that exist in this world which are harmful to humans. Should we make fried chicken illegal? If one guy ate fried chicken every day, three meals a day, and another guy ate copious amounts of bud every day (no lung cancer because he's eating it, douche), which one do you think would die first? ElCid, government should be in the business of keeping *poison* out of the hands of ignorant individuals. MJ can't kill me, no matter how much I eat or smoke. No matter how much I smoke, I can still work smarter and faster, and play better chess, than 95% of people out there. I use chess as an example because it involves many mental activities traditionally associated with 'intelligence'. Therefore, MJ is misclassified as a class A dangerous substance. Therefore, the government, and you by extension, are in the habit of violating my personal liberties, my right to do as I please as long as it does not harm others. I don't appreciate it. I don't owe anyone a fine, community service, nor should I be separated from society if I enjoy smoking MJ.
