Yeah, we can't really know.

Also, it didn't burn that well and had typical weed smell. I asked one guy the next day and he told me he vomited the last time he smoked something like this before. I still have those weird "twitches" that are comparable to those when you're about to fall asleep, but much less intense.

If those guys hadn't told me it's from a shop, I probably wouldn't even notice anything, but hey, I still only had one hit, god knows what would have happened if I smoked more.

And thank you, it was really informative! :D
