Duda, what do you care about a dead snail?? I mean really you're smoking stuff that has been synthesized god know where in the middle of freaking Asia. After synthesis it has been (poorly) washed with acetone, chlorine, benzene, ether or something of the sort. If you are lucky most of those super toxic shit are gone, most of it because there's probably something left, along with some of the original stuff that the acetone was supposed to be washing which is probably far more toxic than acetone itself. Also these chemicals are laced on some stems and leaves of plants that you have no idea what they are, and chances are the guy who manufactures the stuff don't know what all of those plants are (he probably uses some kind of inert herb, but I'm sure that the quality control is not the biggest of his worries-- And since you found a dead snail in there, he is probably lacing the weed he gets from mowing his lawn with cannabinoids and sending it to you)
So, you are more worried about a snail, which has no alkaloids whatsoever and would probably even be nutritious if you ate it rather than being worried about smoking weed from the crazy Asian chemist's lawn, with acetone, with unwashed synthesis residue.
Whatever I've done my share of RC and I've smoked schwag with a sunflower seed in it and I've snorted coke out of baggies taken out of the garbage. Whatever, big picture men, big picture.
