Medicinal vaporizer here. I did have a quick look at the MASSIVE herb grinder thread, however unfortunately no results come up for "mg" (too short keyword?) or for "tiny amount". Basically I'm fortunate in that I can vaporize 25mg or less for my condition i.e tiny or micro amounts. Now, what I'm interested in is getting a grinder which would be suitable for quickly reducing 25mg of herb into powder (or finely ground for such a small amount) for maximum efficiency when vaporizing. Has anyone had any good experience with this? At the moment the best way of doing this I've found is to vaporize the bud twice since after the first vape, the ABV crumbles in powder really easily. However I don't really have time to be vaping twice at the moment and am after a more time efficient method. Cheers Edit: Sometimes I even vaporize 10mg when it's a sativa since I'm fairly sensitive to them. So something capable of effective finely grinding an amount as small as 10mg would be welcome.
