How about we let adults do as they please instead.
The most anybody should ever do about vaping is warn people that maybe it's not the safest thing in the world.
Instead in the EU we have a ridiculous law that makes it illegal to sell nicotine liquid in container bigger than 10ml, which means that if I don't want to spend twice what I used on cigarettes, I have to buy non-nicotine 100ml bottles of liquid and then buy separate 10ml bottles of nicotine concentrate and mix them myself, doing the math myself to get the proportion I used to be able to just order and generating a small pile of empty small plastic bottles every month because people who can't sleep at night unless somebody does something about everything!!!OHGODSTHECHILBREN!!! keep coming up with stupid ideas like that.
Please we should not be making sure of anything! We don't need to be sure that every body is absolutely safe all the time, put a warning label and let us do as we wish with our health.
In America, you break it, you buy it. Everywhere else, I have no problem with a bit of governmental oversight to make sure people don't hurry themselves to a quicker and more expensive death.
Trusting people to their own devices and doing no more than education is not perfect. But it reduces the odds of unintended consequences like this drastically. It also makes it much easier to change course when necessary.
I don't understand why your post is so angry. In England there are no laws that stop people vaping. We have a government organisation that has to make recommendations for public health, and they've given their recommendation.
None of these sources are saying that vaping is comparable to smoking in terms of harms caused.
They're saying that some harm is caused, and that we don't know what harms are caused, and so the precautionary principle means we should make sure that non-smokers do not take up vaping, and that smokers should use other nicotine replacement methods.
