Perhaps we need to ask why the EU wants to ban the most effective means of tobacco harm reduction. Take snus, for example, this is the result of their widespread use in Sweden:
But consider this: Sweden has the EU's lowest rate of male smoking and consequently the lowest rate of lung cancer and emphysema. The health risks of snus are non existent – perhaps explaining why Sweden also has some of the lowest oral and oesophagal cancer rates in the world.
The EU already ban snus everywhere but Sweden. And now they want to ban e-cigarettes - presumably because they're not made by Pfizer and don't seem to make people kill themselves:
Pfizer make the anti-smoking drug varenicline, marketed in the US as Chantix and Champix in the EU. Endorsed by Action on Smoking and Health, it is associated with mood changes, depression and over 200 suicides. Pfizer are now subject to a class action from victim’s families and there is strong evidence that they suppressed these findings before the Food and Drug Administration licensed it.
There is no evidence at all the e-cigarettes harm anyone - not the user, not the person sat alongside, no-one. Yet the EU proposes to stop them - presumably because they're not made by big pharmaceuticals companies.
It seems that the EU, the anti-smoking lobby and 'Big Pharma' would rather smokers die than let them have access to proven means of reducing harm from smoking. And would rather ban e-cigs than fund studies to confirm that they are effective in reducing harm and in encouraging cessation.
