most likely. no idea how much, nor whether it would actually work. no way of knowing which synthetic cannabinoid is in your blend, as the chemical composition changes commonly from brand to brand and from date to date. little pharmacological data exists on most synthetic cannabinoids, and clinical trials are typically done by injection. your call... in the name of science, if you do do it, let us know...
i could be totally wrong btw this is all speculative. also im pretty stoned off some real bud...
personally i HAVE tried spice once, but i didnt like it much. it tastes weird, doesnt last very long, etc.
one thing to be aware of: if you do eat it, and you do a much higher dose than what you would smoke, it could be very dangerous. mentally, you may have a TERRIBLE trip, be waaaay too high, and its a spice high so very unpredictable. another thing is that you can OD, because many synth cannabinoids are full receptor agonists rather than partial agonists, which is what THC is. i dont see why you would want to be higher than what spice does from smoking only a tiny amount....
