The recently legislated generational tobacco purchase ban with the Tobacco and Vapes Act that gained Royal Assent on the 29th of April does not ban future generations of adults from vaping and purchasing vaping material from the market and the shops, as it does with tobacco and all tobacco containing products. The minimum age requirement to purchase vaping material is still 18 years, and future generations of adults will still be eligible to purchase vaping material from the market, although the same does not apply to heated tobacco sticks which contain tobacco, and will not be legally sold to anyone born after 2009.
The underlying philosophy of banning anyone born after 2009 from buying tobacco by raising the minimum age required to do so by one year every year, is to ban all adults who will gain their adulthood after the law is passed from doing so, allowing this to those who were already adults before or when the law was passed, but not to those who will acquire their legal responsibility after the law had been passed and taken effect.
Those who were born in 2009 will become responsible adults in 2028 and will find that they should have been 19 instead of 18 years old to smoke, and progressively in 2029 they will find that they should have been 20 years old and so forth. By that time, all polls indicate that Nigel Farage and Reform UK who are offering to abolish the Act and its generational ban provisions, will have won the general election and will be able to do so (full story). They might as well then designate the age to buy tobacco to 21 years, as Donald Trump did in America in late 2019, so that those who were born in 2009 will enjoy their right to buy tobacco because they will have become 21 years old in 2030, under a possible Reform government led by Nigel Farage as prime minister.
