@jack1010, the US authorities don't really have much if any credibility at the moment.
Nevermind that they're trying to ban vaping.
But a heated Tobacco product is made out to be safer, even though it's not a massive leap of logic to realise that prior research that states the health risks from Tobacco still apply somewhat.
So this could be a big error for the Tobacco industry that may keep it going in the short term, but when users health has been impacted it will be the end of the line for them.
