I have never smoked pot. I heard you don't get high the first time... so I don't know why I should start?
First time I tried it, I was pretty fucking baked. My foot felt like lead. It was so much fun. My friend and I smoked a total of 1 gram. Ahh, those were the days.
I believe that you DO get high, its just when you first smoke, its hard to get used to the shotgun, or getting used to smoking. You have to be with somebody thats done it before, or you have to know how to hold it in, and how to do it perfectly.
If you fuck up too many times, it will have no effect.
