Nobody does this Tincture on a regular basis? Where I come from I know a few people who make and most everybody has tried it and done it when they can.
My buddy takes his stems and shake and soaks it in pure grain alcohol, we can buy it at the liquor stores here, 99% ABV if I'm correct. Soak it in there for 3 months, in this case we're talking about stems and shake. You've got yourself some green dragon. We put two or three drops in beer, taints the whole beer. Put a drop on top of a cookie and you have an edible. Put two drops underneath your tongue and hold back the tears, and you're stoned in seconds. It really is a great little way to be use THC.
Get your bud, get some Everclear, and put in enough weed so that it is a 1:1 ratio with the Everclear and make sure everything is submerged. Let sit for a month to two months and you're golden, you can make fat batches easily. Apparently it sells pretty well too, I don't know though, I've only heard that. I've never actually found some for sale for whatever reason.
