We have similar ads on tobacco products here in the UK and have had them for the last 2 years.
You have to be an adult (18+) to buy tobacco in the UK, but the government sees fit to treat those adults like children. Those that smoke are very well aware of the side effects of smoke and as adults are also aware that they have a choice.
A bit hypocritical of ANY government to warn you of the dangers, but yet gain so much in revenue from it.
One could argue that the £10.5 billion duty & tax from tobacco (£8 billion after taking out the £2.5 billion needed to treat smoking related illnesses) in the UK alone, would be better spent on promoting giving up and the therapy/drugs/councilling needed to do that.
But hey! wait a minute... where are they going to find £10.5 billion from if everybody gives up?
And while we are at it, if everybody gave up smoking, will the government health department start to insist that all new babies be stamped with a government health warning saying "Life is bad for your health, it will kill you"?
Now THESE are interesting questions to ask a politician. However, don't hold your breath for a sensible or even a truthful answer.
