ive tried salvia before so i have a stem pipe and a bong. i smoke port royals, so i know how to roll a joint. so i break it all apart, and just roll one as if i was rolling tobacco? well, i tried that. smoked half the joint before i started feeling effects. mostly its a WEIRD headache and some buzzing here and there. not pleasant at all. it also kept popping as i smoked it, from the seeds i gather, but i couldnt find any. precisely what should i be looking for?
