Reason for worldwide governments banning or restricting E Cigarette related items is simply about PROFITS.
Notwithstanding any conclusive studies showing ill effects of vaping.
There cannot be any other explanation.
Bottom line: Governments lose TAX revenue as a significant portion of the population moves to this alternative.
If they cannot create logical reasons and support to make their CUT $$ , then they will assert their authority by banning it.
With this reasoning, they are siding with EVIL.
EVIL meaning they would rather see people kill themselves with analogs rather than applaud efforts by an exponentially growing percentage of the population move to better their lives.
No different than the Mafia.
