This has been said for a long time and I believe it's true...
From Walter E. Williams:
Here's how my June 14, 2006, column started: "Down through the years, I've attempted to warn my fellow Americans about the tyrannical precedent and template for further tyranny set by anti-tobacco zealots ... .
"In the early stages of the anti-tobacco campaign, there were calls for 'reasonable' measures such as non-smoking sections on airplanes and health warnings on cigarette packs. In the 1970s, no one would have ever believed such measures would have evolved into today's level of attack on smokers, which includes confiscatory cigarette taxes and bans on outdoor smoking. The door was opened, and the zealots took over."
