umm, well ill try to help you out... me and my friend made brownies bout a week ago, we put in about 1/2 - 3/4 o of regs in a 9x9 i think i was pan of brownies... i had about 3 of them, he had about 3, and we let other friends have like 1 a piece... he and i smoke alot, and we felt pretty good off it, and so did the other people (who didnt smoke a whole lot)

so i guess a 1/2 - 3/4 o of regs will do 3 heavy users pretty good...

btw it was kinda hard to tell how long it took to work and how long it lasted cause we were baked when we made them and continued to smoke throught the night lol sooo... but it was fun anyways
