Cure the disease, and everyone benefits, tobacco user or not.
Then there was no need to bring up tobacco.
The AIDS crowd didn't want to change their behavior, they wanted a cure instead.
You are the one who brought up AIDS, whoch really does not relate to the thread.
It may not bother the rabid antismoker that so much money has been spent for the purpose of attempting to lend scientific creedence to the known fact that cigarettes are bad for you.
After all, warnings have been on the pack since the '60s and the term 'coffin nail' goes back much farther.
I will, however, continue to maintain that that money would be (and would have been) better spent on researching the mechanisms of cancer and stopping the disease, regardless of cause.
Don't forget the sarcasm tag.
