A Generational Tobacco Ban (also known as a "Smokefree Generation" or a "Generational Endgame" policy) is a proposed method of gradually phasing out the legal sale of tobacco products in which the legal smoking age would be raised by one year, every year, until the entirety of the population is under the legal age of sale. The aim is a gradual phasing out of legal tobacco sales, as opposed to the disruption that would be caused by an immediate prohibition.

Theory
Suppose that a generational tobacco ban policy were implemented in 2010, in a country where the current smoking age is 18. with the intended effect of preventing those turning ten that year from ever legally purchasing tobacco. A cutoff date would be created - January 1, 2000. For anyone born prior to this date, the previous smoking age of 18 would still apply, but anyone born on or after this date would never be legally sold tobacco products. This means 2017 (the year in which those born in 1999 would turn 18) would be the last year in which new legal tobacco purchasers would be created.

Over a timeframe of decades, the percentage of the population born prior to 2000 will gradually decrease until the legal tobacco market is negligible.
