hi, first, an introduction. i've been looking around on this forum for a while. i've been smoking heavily for almost three years.

my first question is about butter yield. i made a batch of brownies yesterday, with 1 ounce of shwag and 1 lb (2 cups) of butter. i simmered them in water for about 3 hours. when i strained all the material i was left with 1 cup of cannabutter! is this supposed to happen or did i somehow f*ck up royally?

my second question is, last time i made brownies, they were VERY effective. after sitting in my freezer for a week, they seemed to lose a lot of potency. why is that?

thanks for any help!
