No student you misunderstanda me, i don't mean synthetic cannabinoid smoking blends, i mean the old fashioned weed imitator herbs, things espoused as weed-lite since the 70s (and no i am not that old). you know, wild dagga (leonotis leonurus), damiana (turnera diffusa), zornia, wild lettuce (lactuca) mugwort (artemisia vulgaris), that sort of thing, as in they do something, but not get you stoned per se.
Actually mugwort is one of the best to mix with cannabis i think, it mixes physically very well, evenly and results in an easy to handle fluffy mix, produces clouds of easy to inhale smoke and enhances the weed high in a positive way. more euphoric, but also easier to get to sleep, without being sedating. also it purportedly enhances dreams, an effect i find hard to substantiate considering my dreams are already very vivid.
re: mixing weed with synthetic cannabinoids. i haven't tried this yet, though agree that both are enjoyable on their own. i can also definitely see getting in too deep. i even got too deep on one HHH synth blend, started to freak a bit, but a strange thing happened. this was the third time i smoked that evening, and every time the duration of the effects diminished substantially. first time: ~45 minutes, with 10 minute lingering effect. second time: ~30 minutes with 5 minute lingering. third time i freaked out, it only lasted about 7 minutes before i felt mostly sobre again (except for a few beers). very odd. i have also heard people say that 'beer then grass, you're on your ass' doesn't apply with synthetics. but anyway i digress.
finally, i have a theory about synthetic cannabinoids. now, obviously, these blends have all sorts of crap in them in varying combinations depending on the brand and current legal status (one kronic even tested positive for benzodiazepines, and the newer blends to get around the ban sound very dangerous. how good is prohibition??). anyway, with jwh compunds at least, they are full agonists of the CB1 receptor. however THC is only a partial agonist. this is why it can't kill you, and why synthetics are therefore more dangerous. MY POINT IS finally, that i think you could probably use thc (in weed) as an antidote to a synth overdose. but don't take my word for it.
