JWH-200 was imo lackluster.
It's MUCH less potent, and I wasn't able to get even the pale imitation of a weed high off it (like I can with 018), while being just as much of a likely carcinogen per mg. The high is no better than AM-694 (which isn't likely to be carcinogenic), while requiring more than 10x as much material.
I was not impressed with it at all.
And none of the indole cannabinoids come close to CP-55,940, which is unfortunately expensive as hell and hard to find.
