as a preface, someone is going to call you a pussy soon.
if you dont ever use tobacco products, i guess that could happen. like if you inhale a whole cigar, youre probably going to puke your guts out. if you swallow a dip, same thing. if you smoked a lot of hookah for a long time, it could conceivably happen. its just too much tobacco in your system, and your body pukes, like it does when you drink too much
if you do meet up with him bring a lighter so if he tries to moleste you light him on fire. be sure to warn him first though because most people dont like being lit on fire.
