I pay 20 per gram for nice bid, and if I smoked a joint with a gram in it I'd be fucked up for 2+ hours and be buzzed for 3 and a half + hours. I say that it really depends on the person, everyone is different with how they handel themselves while on weed. I have a friend who I smoked down then could barely order popcorn when we went to see a movie, and would just say stupid shit (which of course made me laugh since I was high, but only because I knew the girl behind the counter was hot and knew I was stoned.) which totally gave away our condition. I personally can always control myself if I have to, but that ends up being a major buzz kill. Eat mints, buy clear eyes (THE ONLY DROPS THAT I'VE FOUND TO ACTUALLY WORK, VISINE DOESNT DO SHIT!) and just try to find a place that you and your friends wont be bothered by people who'd care if you were high. After you smoke a few times you'll know whether or not you can control yourself, just smoke in a safe enviornment and find out for yourself.
