is it time to bring in more restrictions on this?

Australia have banned all vapes other than via prescription.

some of these vapes release huge amounts of tiny metallic particles into the body, which we have no idea what the long term effects are going to be (I'm sure it's not good though)

back when I was in school, only a small proportion of kids smoked, maybe 0-5% from the end of primary school rising to 25-30% by the end of secondary school .

according to my kids, and a load of teachers I know, vaping is absolutely rife in schools now. like 50% of year 7s regularly vaping - far far higher than the equivalent cigarette usage before they brought in vapes.
