just made some butter

Actually, that's incorrect. Any form of oil, be it olive, canola, corn, sunflower, or milkfat, will gladly bond with THC. Margarine will work just as well as real butter. In fact, if you do use real butter, the resulting solids are not butter anymore, just saturated fats. Butter is part oil, part water, and part protein. You can make cannabis olive oil for salad dressing if you want, just simmer some oil with water in a pan, and make sure you don't let all the water evaporate. Unfortunately, since olive oil doesn't solidify like milkfat does, it's harder to strain and store the product. But it's just as worthwhile, trust me :)

we made some bud butter once and i tried eating it straight on toast and the cold nasty butter/weed taste made me gag lol, then i put it in my freezer for another day to bake into something but tha day never came aorund and its still sitting there

well i still have a tablespoon or two left of the shit.

i had maybe 1/2 tbsp.

do i need to heat it up again to activate the thc, or could i possibly just throw it on a piece of bread or something and feel it?
