Yeah, parachuting is a much better option than straight up chewing a roll when you compare the nasty taste and the lack thereof. Unfortunately my habit of chewing e was out of unpleasant necessity, since lots of times I've overestimated my ability to dry-swallow and end up with a slowly dissolving pill or gelcap stuck in my mouth and at that point it's like, well I can't spit it out since it's already falling apart, might as well just suffer the horrible taste of chewing it.
I feel like there might actually be some advantage to chewing it in your mouth though, since many substances like lsd and phenibut seem to absorb better and come up faster/harder if you let them absorb in your mouth rather than stomach. If the same is true for MDMA, then the most efficient and, unfortunately, the nastiest tasting way should be to finely chew up the pill or powder and let it sit under your tongue, since under the tongue is reputedly the best spot for tabs to absorb, prolly due to there being an abundance of blood vessels or especially thin skin there. Actually, might have to try doing that next time I roll, comeup's probably damn near instant since just chewing alone usually reduces it for me to ten to twenty minutes max.
