I guess you don't need to strain it but i at some point you have extracted everything that you're after so there is no reason to keep it in there. Plus it adds a lot of bulk to it when its material and liquid versus just the liquid which i keep in a small vial. yes this is designed to be udner the tongue. Dispensaries carry tincture that just a couple of drops will satisfy, this is less potent so you need more. You can take a dropper full in the mouth, but I usually just squirt it into a cocktail or beer .
^^so you don't really use it under your tongue then? you just drink it in a mixed drink.. got any good ideas for vaporized weed leftovers, TheShow?
I'm not a huge fan of the flavor so I go with a cocktail, works all the same. I just usually dump the vape leftovers....that light brown color sitting in ajar just doesn't appeal to me. I imagine you could use those for a tincture extraction or I know some friends who just make butter or cooking oil with them....they'd be perfect for a batch of Joker's mini pot peanut butter cups I say
