A Hawaii lawmaker believes that cigarettes are “the deadliest artifact in human history”.

A new bill introduced by Representative Richard Creagan proposes to gradually increase the minimum age to buy cigarettes. Each year the cigarette-purchasing age will increase by 10 years: 30 by 2020, 40 by 2021, 50 by 2022, 60 in 2023, and up to 100 by 2024. The ban doesn’t apply to electronic cigarettes, tobacco, and cigars.

Hawaii is the most strict US state in its cigarette policy. In 2016 it was the first state to increase the age to buy cigarettes to 21.

The reason why the ban will be imposed gradually is to find ways to adjust for the lost cigarette tax revenue. Each year Hawaii receive approximately $100 million dollars from cigarette sales taxes.
