ok i've used two different methods to make weed tea:

my personal recipe is called "goofy green tea"- start by melting/simmering a teaspoon of butter with 1-2 grams of finely ground bud. when it's simmered a bit, add 1 cup milk, one cup water, and boil. once it has boiled, add green tea bags, vanilla, and honey to taste. if you simmer it for about an hour the thc gets pretty absorbed in the tea. then put the whole mixture in a strainer, you dont want to be drinking weed. i tried this today and got pretty high...it extends your smoking high more than anything. you feel a bit burnt out for a while after. i think the longer you boil the tea the higher you'll get. it lasts quite a while.

the other way just involves emptying out a tea bag and replacing it with 2 grams of weed. add that to 1 cup water with 1 tsp butter already dissolved. then add tea bags, allspice, vanilla, milk, etc. to taste while boiling for up to an hour. this got me less high than the other recipie.

because you're drinking butter, in effect, it tastes kinda weird. just drink it all down with a lot of honey and make sure it's really hot.
