Hey there
When i make brownies I use at least 2-4 grams and 8g if I want stronger brownies. Buy some brownies that use oil and buy some vegetable oil. Grind up the weed fine, get a pan on the stove and put a little more oil than the recipe calls for in there. Put ground weed in there so all of it is submerged, stir it around and turn the heat up to low or 2. maybe 3 depending on your stove but you don't want the oil to smoke or crackle or act up in any way, it should just calmly sit on the heat for 30 minutes to 2 hours, however long you feel necessary. Stir occasionally. Then you remove it from the heat, pour it into a seperate container, like a pyrex measuring cup, through a fine strainer. I use a pretty fine meshed one, but its big enough to let some of the finer particles through, which is a good thing for some, but not for people who dislike the taste. So now you have your oil. Let it cool down, mix up the brownies according to the recipe using the marijuana cooking oil and you are gonna get high as f*!@. It smells really weedy when you cook the oil, but the brownies just smell delicious.
