One thing I've wondered about for a long time is why they continue to allow cigarettes to be sold. The health impact is so well-documented. It's effects are almost as bad as some narcotics. Drugs have been pulled from the market for having effects less detrimental than cigarettes. So why are these things still sold? What is going through the heads of the people making law? Why is there a perception of cigarettes as somehow being more acceptable? What is the psychology behind this?
