what did i do wrong???

i tried to make weed brownies last night but they like didn't do anything...i put the oil on the stove and warmed it up a little bit. While i did that i finely chopped up a little more than an 8th of weed but not a quarters worth and then put it in the oil...it sizzled at first but then stopped after about a minute...i then cooked it on the stove for like 20 minutes and then mixed it into the brownie batter and baked the brownies. They looked awesome and shit, let them cool...tasted amazing...however i didn't get royally ripped...in fact me and my 2 buddies ate the whole pan and none of us got ripped...did i just have really shity weed (which i think it was) or did i fuck up somehow?

a 1/8 of shitty weed won't do it.

You need at least a 1/4 of commercial for brownies. I like to use a 1/2.
