From the reports I've seen on TV vaping is a seriously addictive problem for youngsters. Some are admitted to hospital very ill with popcorn lung which I believe is permanent. Anyone with children or grandchildren in the 10-15 age bracket needs to have some serious conversations with them about this, although for many this may be too late.
There is a big problem around illegal vapes which (like illegal drugs) contain all sorts of horrible things which can make them ill. So don't go thinking they are just smoking nice legal vapes, they are not. Like heroin, which on its own is a clean and much less harmful substance, it becomes totally toxic and deadly when the dealers mix drain cleaner and other vile substances in with it, making the users terribly ill. The same is happening with vapes. We need to do everything possible to keep the children off them.
