i remember the first time i got high, the first time i had actually smoked/inhaled anything. The best part was i took 2 hits, and got high, and was fine with that, then i went to another friends house, and they said no one gets high the first time, and i pretty much looked at him and told him to tell me i wasnt high.

You just have to inhale and you will always get high. Just copy whoever is the highest, they will know how to get you high, just watch what they do.
