I usually vape it until it is light brown and popcorn tasting. I save the leftovers to make butter with and it still works. 2 highs from one stash... can't beat that.

I must admit, though, I am one who does not like the bc or other "heat element" type vaporizers. I use the vapobros personally (the little wooden box one) and it works GREAT! I have also used the Volcano which is amazing but super expensive. I have known people who use the volcano to fill bags with vapor and leave the bag to sit over night and supposedly it still works.
