Puking on your friend is funny? I would get seriously pissed you should know what to do before you do it.. respect it man wtf puking on somebody just because of ur ignorance? Iunno i've never puked on DXM and yesh it does smell terrible in its pure form but so does DMT and other chemicals. It could be phycelogical, but it could also be an alergic reaction towards inactive ingredients so your pretty much fuked just deal with it.
