Sunak is looking at anti-smoking measures similar to laws New Zealand announced last year, which include a ban on selling tobacco to anyone born on or after Jan. 1, 2009, the report said.
"We want to encourage more people to quit and meet our ambition to be smokefree by 2030, which is why we have already taken steps to reduce smoking rates," a British government spokesperson said in an emailed response to Reuters.
Those measures include free vape kits, a voucher scheme to incentivise pregnant women to quit, and consulting on mandatory cigarette pack inserts, the spokesperson added.
Separately, councils in England and Wales in July called on the government to ban the sale of single-use vapes by 2024 on both environmental and health grounds.
