I used some cannabutter in for some brownies I made around 3 weeks ago, just used some compressed swag since it was my first time doing it, the brownies ended up doing pretty good, I simmered a quarter and half a tub of butter in a pot for around an hour, then strained the weed out of the butter and only had enough butter to make 1 batch, took around an hour for any effects to start kicking in. 2 hours after eating, really felt like I was getting close to the top of the mountain, 3 hours later I realized just how big the mountain was, and the peak lasted for around 2-3 hours, when it wore off it was so gradual it lasted another 3-4 hours, so all in all I'd say off 1 brownie I got 8 hours of effect, 6 of which was pretty intense.

I will say though, the brownies definately did not taste good by themselves, had to have icecream and fudge and other flavor maskers, as the weed taste from the butter was quite strong.
