I find this proposed solution overengineered. Of course it could be enforced. "Smart" vapes could be regulated as medical devices, available only by prescription and used under the supervision of doctors. I think that would greatly reduce their appeal as a smoking replacement with a low barrier to entry though; other nicotine delivery systems to aid in quitting smoking were available decades before vaping.
