good idea torog! Something i do (dunno if it has been mentioned) is i always save my metal screens when i change them, wad em up and smoke em in a pipe, they have lots of resin. I also never boil my pipes to clean, i always scrape off the resin for more to smoke.

If you don't feel like cleaning the stems as much, i heard you can make tea out of them (although i don't suspect it would be very strong if they are completley devoid of all weed)

lastly, always keep a butane lighter handy. Cash your bowl as you normally do with a normal lighter. But before you throw it out run a couple of hits with a butane (the little torch) lighters, even when a bowl is completley gone i can always get a few fairly potent hits by using butane.
