I encountered something really weird last night. I smoked a buttload of some potent sativa, was really high like normal. Then I bought this double-filtration bubbler, thing is pretty good, too good. After a couple of bowls off this new piece, I started to feel really dizzy and had to lie down. Passed out for a few hours and awoke, my head was spinning in circles and I felt really cold. All night long, I felt like I had some huge fever and felt this incredible vertigo. Man it was weird. I feel like a newbie.
