I still think that's utter bullshit.
Some people get high on the first try. One of my friends from home got REALLY high his first time, and he bugged out hardcore; he got lost on his way to the bathroom, forgot he was in there, and then he called his mom to tell her he smoked. It was pretty hilarious.
Still, the vast majority of people I know didn't get high after round one. I think I didn't get high until my third or fourth time. I thought the couch was eating me.
