Its efficient, but it isn't a nice way to go. They use it in some labs at
the university for their mice, but some researchers have completely banned
in their labs*, in favour of cervical dislocation as they don't feel that
CO2 is a good way to do it (cervical dislocation takes more skill, and
more time to do, but they feel that it is a much more humane way to go
when its done properly).

I've only seen cervical dislocation used in the mouse/rat labs I'm familiar
with.
