I have an experience here relating to using these chems to potentiate a trip. I dropped a hit of lucy today and smoked quite a bit of JWH-018. What I can say is that yes, it does enhance the trip in a similar way to weed, but if you get just a tiny bit too much (which is easy while tripping), it will fuck you up royally. I apologize for the pussy comment I put earlier in this thread. Never gotten it from acid, weed, shrooms, or anything else, but JWH-018 gave me the fear. I got an uncomfortable feeling in my chest, and I swear I thought my heart stopped beating for a minute. It felt cold, and I felt some fear. With these compounds being so untested, this really is dangerous territory, and JWH-018 does hit me, not just with paranoia, but with actual physical side effects that weed does not and which do frighten me somewhat.
All that said, I still love JWH-018. At low doses, it dominates. Like a really nice pot high. But at high doses...woah mama, stay away. I thought I was a hard-head and that I could take it, but on lucy, a high dose of JWH KICKED MY ASS. And even without acid in the background, this stuff damn near gave me a panic attack. Be warned. I chugged down 4 bottles of water in less than 20 minutes when I started freaking out. I thought it work somehow make me come down, so I stuck with that plan, and it worked. But there was a solid hour or so that I was genuinely scared, and until more tests come out on these compounds, I won't be messing with anything more than minuscule doses.
