damnit unforgiven, what justification do you have for trying to force your marijuana-smoking vice on others??? Even after everyone pwns all your terrible points, you keep using them...
For instance, profanity clearly states he has smoked pot before, but it played a role in giving him brain injuries when he fell, and now those things can permanantly mess him up if he's near it. Here you are, retorting to his quote to not judge anything until he's tried it, which he has, and that it will leave his system, but wait, he has a brain injury, so how would you know what effect THC has on him in his special case???
It's obvious that being a stoner has made you oblivious to reason. With time, your mind with rapidly deteriorate, your lungs full of tar and cancer, and you will be yet another invalid human being, lacking coherency and valid ideals and opinions. An irritating dingleberry on societies ass, if you will.
