once again you need to stop with the assumptions that drinking or smoking is for popularity....as for a 'short high'...well assuming he's like me, he smokes because he wants to and likes to....I didn't even like going to parties or any crap like that. It's no different than people wanting to smoke cigerettes
Shit happens....this is why when I did smoke, I'd simply be very careful about it and discreet...especially after this one friend of mine was a dumbass who got caught smoking in the bathroom at school....I never smoked at school or before school, screw that.
So yeah, situation sucks, but atleast you'll probably be more discreet in the future
