@I'm In The Minority
Yes, you are.
"As AC pointed out above, it is likely that at least some of the "high" passengers would freak out when the plane hits turbulence, and would cause much more of a scene than any non-stoned-but-afraid-to-fly person"
Now, this might be where I'm in the minority, but I've met a LOT of potheads, and I've not actually encountered one that "freaked out". I've seen a fair few people "whitey"* (smoke too much, they go a ghostly shade of white, start being sick, etc), and they're nothing to worry about if turbulence hits, just leave them in the corner rocking gently. Aside from that, the worst thats going to happen, is a fit of the giggles (no matter how bad the situation). I remember my first bong, it was supposed to be packed for four people, and I cleared it (I didn't know what I was doing). I couldn't have freaked out if I wanted to! I spent half an hour coughing my lungs up, and the next hour laughing constantly, at nothing in particular. I miss those days.
But anyway, I digress. The only people who "freak out" when getting high, are the kind of people who "freak out" even when they're not high. The kind of people who take two tokes, say "whoa, man", and think they are part of the revolution.
*To this day, I've never whitied. Anyone who thinks they can outsmoke me, let me know - you're wrong.
