A vaporizer or knifehit would be a cleaner hit, infact a good knife hit leaves behind brown worthless nugget that has been stripped of its goodies, you can throw that junk away and save your lungs the tar!
Also when taking a knife hit.. the smoke is boom , burned, then instantly sucked into your lungs, so the time from combustion to inhaling i very very minimal - I know bong hits get stale rather fast so this must be more effective :P Just burns thru alot of weed since you dont get as many " hits " per gram. But you still get all the THC and other goodies.
ps. Just use matches if you burn your weed with flame - let the sulphur burn off first though :P joints are also a cleaner method.
