Update, if anyone cares.
I used an ounce of leaf from some okay weed plants to make ten cookies.
Boiled the weed with some butter for about six hours, and chucked it into a Betty Crocker cookie mix that called for butter.
I don't have much of a tolerance any more these days, but my natural tolerance has always been a little higher than average. One cookie got me completely fucked. My whole body was buzzing and I had a few serious 'moments' listening to the new Radiohead album. I definitely wouldn't want to be any more stoned than that, but it was good.
