This is horribly duplicitous. I definitely think more regulation is needed to discourage teen vaping, but more than anything, such a ban would just help big tobacco and cigarette sales more than anything, who are losing billions due to vaping, which overall is much safer than smoking cigarettes.
While Big Tobacco makes a huge amount of money from vaping, it pales into insignificance compared with what they make from tobacco.
There’s a report here on their tactics.
