I got a 50mg sample of some JWH-018 that is a very clean looking white powder. Some of it almost looks clear and kind of shines. I believe this is very pure JWH, and a very small eyeballed dose (estimated to be 2-3 mg) can get me damn stoned, and about double that amount will annihilate me, which is impressive to me as I've been smoking daily with only maybe 3 or 4 total breaks for about a year and a half.
I tried a dose that was about double what I normally use last night (probably in the neighborhood of 5-7 mg) and I was getting some definite visuals. They were mild, but psychedelic. I was trying to help my girlfriend with an English paper and I noticed it looked like it was covered in pink and yellow highlighter. She said she hadn't used any, and I was confused as to whether or not I was really *that* high. Then the highlighter marks started moving around and arranging themselves into shapes and I knew I was, in fact, *that* high.
Also, looking at myself in the mirror proved stranger than any psychedelics I've tried (and I've done my fair share of acid). My face didn't morph or melt or anything, but it just looked so damn strange and cartoony. JWH has a very surreal feel to it, IMO. If I smoke enough of it, it feels like something in between good sativa and a "true" psychedelic. It feels like walking into a cartoon...a cartoon in which you're ungodly stoned. I've had good hash that produced similar effects, but not often. 018 also seems to give me the vibe of being an "explorer," kind of like I'm on a mission...and kind of like I'm a little kid at the same time. Very interesting substance, and definitely worthy of more research.
