Now if you GRIND UP your stems and save them for a really long time, grind them up with some leaf and let the flour sit in some everclear for a half hour or more (the longer it sits the more stuff that won't get you high from the plant's gonna come out) ... run the alcohol and plant matter through two coffee filters and pour it onto a large glass pan, let it evaporate overnight or faster with a fan, then scrape that up...
You could smoke that and it'd be way less wasteful and HORRIBLE than smoking the stems themselves. It would ALSO help a lot to put some leaf or even a couple of buds into the coffee grinder with the stems, the potency difference'll be noticeable.
