Seeds are for planting, not smoking as there is no THC in a seed.

Stems have very little THC on them, so it's best to shake the kif from them, and smoke it that way, but 10g's of stems will only give you 1 or 2 bong rips. You need an awful lot of them to get anything. Smoking them as whole is just smoking filler, and is just unpleasant.

You could make a green dragon with them, or even oil (the stems).
