Well 125 days ago I had my last cigarette - after 55 years of smoking. Basically I gave it up because of the horrendous cost and as a retiree I simply couldn't afford it anymore.
I remember a movie they showed us when I joined the Navy all those years ago and they showed the autopsied lungs of a smoker, it didn't stop me, but I remember it as if it was yesterday.
So although I consider the tax impost on tobacco a blatant grab for money, pricing has had a positive effect, in my case - But perhaps it would have been better for the government to have simply banned cigarettes back in the 60's. I am sure that there would be a lot more taxpayers alive paying much more tax than they would have forsaken by banning the sale of cigarettes.
Perhaps a group could lobby for cigarettes to be supplied by licenced outlets to persons born prior to 1970/80 or such so addicted people could be let do what was legal when they started the habit. But no more would this incidious product effect the youth.
