39 years and have never had one!! Not planning to start now. Least favorite memories are of mom, brushing out my looong hair, blowing smoke in my face and breathing coffee breath in the morning! So much for a happy childhood. Like many in this thread, growing up around it really turned me off.
I abhor sitting in a fine reastuarant and having someone blowing contaminants in my food!! When asked if I mind someone smoking, I have been known to ask if they would mind if I injected them with cyanide and embalming fluid. They usually only ask once.
I applaud states that prohibit smoking in public places. I appreciate the fact that nicotine is addictive, but I don't feel like shortening my own life expectancy to support your addiction.
A little extreme? Maybe, but I have lost friends and family to the ill effects. My father in law CONTINUED to smoke after losing one lung. It finally got him, it was long, ugly and painful. I am amazed when I walk up to the front of a hospital (I work in healthcare) and see all the patients, out front, lighting up. Many of whom are in for cardiac, pulmonary and cancer treatments due to their addiction...
As for the message that smoking isn't healthy, I believe the first warnings were issued in the 1700's by one of the British monarchy - history buffs help me out here.
