What's in a Smoke?

I've been after my hubby and my father quitting cigarette smoking for what seems like years! They still don't listen. I am thinking of printing this picture of the constituents of cigarettes. Take a good look at it and tell me if it is healthy?

What are cigarettes? Cigarettes are manufactured out of cured and finely cut tobacco leaves and reconstituted tobacco, combined with other additives, then rolled or stuffed into a paper-wrapped cylinder. Hmmm seems pretty harmless, don't you think? I mean, cigarettes come from plants so they must be healthy, right? WRONG! It is the added chemicals to cigarettes that make them toxic.

Cigarettes are proven to be highly addictive, as well as a cause of multiple types of cancer, heart disease, respiratory disease, circulatory disease, birth defects (which include mental and physical disability) and emphysema.
