Oh but don't they?

People who don't do cardio might be more likely to have a heart attack while driving, or otherwise drive at a lower level of alertness (cardio improved cognitive performance and slows decline) hence increasing their chances of hitting someone.

Or perhaps they cost the state more in health (tbh probably like smokers they cost less but this is the common justification for the sin tax on smoking) which damages your ability to get your health issues attended too.

People drinking alcohol are more likely to engage in violence, and do actually pose a risk to people around them statistically.

Obvs this stuff is reaching, but so is most of the health stuff on vaping so far (most harm demonstrated is due to 'popcorn lung' which is basically a result of lack of regulation meaning a certain flavour got used despite this known side effect) and the point is we need to consider degrees.

We live in a society and there aren't super clear boundaries on what we ought to be able to do. The current proposed law, which again I'm broadly in favour of, does massively fuck up by placing vapes under the TGA. That means they need to be regulated as medical devices which means unless you can show a vape has a medical reason to be on the market it wont be approved.

Since that will never happen (except, maybe as a cessation tool but the TGA will have high standards of evidence) this is still a ban on vaping, just the long way round. Note how CBD is legal and OTC except there are no approved CBD products for OTC.
