There's generally nothing wrong with discouraging bad habits which harm people and their loved ones. If people want to have a National Non-Smoking Day that is certainly their right. On the other hand, if someone wants to assume all risks for their chosen behaviors they should and do have that right, too.
I think the National Smokeout Day is hilarious! The non-smokers already don't smoke, so it's superfluous for them. It's AIMED at smokers. What I wish we had was one day when everyone could smoke ANYWHERE--work, beach, bar, restaurants, every place that's banned it. That would only be fair.
Who are you and what have you done with CJ? ;^)
