Can’t we make some sort of waxy nanostructure material in the form of a cigarette that burns with zero particulates? Won’t help the issue directly but will help smokers. Here’s an idea - since all vapes except home made devices are electronic, put a Bluetooth chip that requires a phone app that securely identifies the age of the vaper. Make it mandatory for all vaping devices and boom - massive cut in underage vaping.
