I think vaping flavoring is why the ban.
Teens are trying again.
Vaping here in China is pretty much impossible now, unless you're in Beijing or Shanghai. Because online sales are now banned, and just about all local vape shops closed down. Compare to 2017-2018, and vaping was very popular. I even went to a couple of vaping shows as well, like the Beijing Vape World Expo
Of course menthol cigs are widely available, and are cheap.
