The one about cigarettes:

To an ulcer, it's a shot of booze
to a weak heart, it's some shocking news,
to a deep cut, it could be gangrene,
to a smoker, nicotine.

To a sheriff, it's a top gun shot,
to a rustler, it's a hangman's knot,
to a cowboy, it's a wild stampede,
to a smoker, it's a weed.

To a bigot, it's a Jew next door,
to a klansman, it's a guy from CORE,'

??

I think the lines after 'guy from CORE' are:

To a Bircher, it's a Commie nut.
To a smoker, it's a butt!

And either at the beginning or end, there was the 'slogan':

Misery is the taste of death! Misery is the taste of death!
