Interesting.
So that means that Spice, which keeps me high for 5-6 hours, must have something other than a JWH in it, right?
Whereas K2, which lasts 2+ hours, must not have a WIN/CP compound in it.
Well, I know for a fact that it (Spice, maybe others) has Cis-9,10-octadecenoamide. The exact WIN or CP or other Cannabinoid(s) they use is unknown (and this is likely for most blends, now that there are so many of them out now).
I have tried to replicate the Spice-high (with duration) and haven't been able to exactly (they must have access to other ones, not as publicized; CP55,940, HU-308, HU-331) .. but even if you mix in a bit of -018, -073, and Cis-9,10-octadecenoamide together; that extends the duration a bit (about 30-60 mins longer than with -018/-073 on its own [not sure why though]). I imagine then if you add in CP47,497 or a WIN55, 212-2, also (with the Cis-9,10-octadecenoamide too) you could expect a full-on Cannabis like high (4-6+ hour) or basically as close as you can get to Spice or Cannabis.
JWH-018 and -073 only last about 1-2 hours max, rarely 2, IME. Combine them though, and they synergize, definitely to the 2 hour mark sometimes 3. Add in Cis-9,10-octadecenoamide, and for some reason you now are at the 3 hour mark.
With -018/-073 and CP47,497 you're at the 4 hour mark, maybe longer. With -018/-073 and WIN55,212-2 you're at the 4-5 hour mark (again maybe longer all depending on tolerance).
Unfortunately, I haven't been able to combine Cis-9,10-octadecenoamide along with CP47,497 or WIN55,212-2 (and the rest, either 4 or 5 together) because, atm, I no longer have access to any CP or WIN compounds.... but the key to replicating the Cannabis high is combining them. It seems that CP47,497 and WIN55,212-2 have the ability to perform on their own. However, again, this is only one Cannabinoid. When you're consuming/smoking/vaping Cannabis, that's many cannabinoids, we know in the 200 range, but that doesn't mean there cant be much, much more waiting to be discovered.
