Pot ber Brownie?

Hey everyone, I have a question. How much pot is in each magic brownie? I mean, How much pot per brownie if you were to eat only one and to get high as well? I was thinking an eighth per brownie for really extreme brownies...hehe extreme brownies. Would this work? I am planning on making like two brownies alone and putting eighth in each one and eating them...help?:confused:

i use a 1/2 Oz of dirt, to make 1 tray (12-14) , they come out fine...so I guess about a grams worth?

aw thanks there...
