What may happen in New Zealand 65 years after the law concerning smoking takes effect?

New Zealand’s government believes it has come up with a new plan to end tobacco smoking. A lifetime ban for those aged 14 or younger. Under a new law the government plans to pass in 2022, the lowest age to buy cigarettes would keep rising year after year. The yearly increase could mean that 65 years after the law takes effect. Shoppers could still buy cigarettes, but only if they could prove they were at least 80 years old. Officials hope smoking will disappear many years before then. The new plan sets a goal of having fewer than 5％ of New Zealanders smoking by 2025.
