I'm not surprised by this, and I have no doubt that in 30-50 years time most countries in the world will ban the sale of cigarettes. This may seem unbelievable now, but then again, who would have thought 30 years ago that you would not be allowed to smoke in public places including some parks.
Cigarettes are a legal drug. Alcohol is too of course, but the key difference is alcohol can be consumed in small quantities with no effects on health. In some cases it might actually be good for you.
Cigarettes are plain and simple deadly, and therefore there is no reason for them to be allowed on sale.
I'm guessing countries around the world are waiting for the first to ban them completely, then others will follow suit. Tax revenue or not it will happen in my opinion.
By the way I'm a smoker trying to give up, so if I was unable to buy them at all, that would be a huge help.
