While on the subject of warnings, and shortly after resuming smoking after a self-imposed one month ban, here are my personal favourite alternate warnings for cigarrette packets.
smoking kills time.
smoking is a small act of rebellion.
smoking gives you 5 minute breaks during the day.
smoking annoys people you don’t mind annoying.
There is a much more comprehensive list here. but it’s not so good (i.e. someone else wrote them).

Poor, deluded Russell:
smoking kills you slowly, so you can go on servicing the man.
smoking feels like rebellion, but it’s actually a sorrowful act of conformity.
smoking takes up five minutes that you could spend thinking how not to support the GOP.
smoking annoys people who aren’t self-deluded
Get a haircut and a job, junkie!
