A UK ban on future generations buying cigarettes will come into law this week.
The Tobacco and Vapes Bill, which introduces a rolling age restriction permanently barring anyone born on or after January 1, 2009 from legally buying cigarettes, was approved last week.
The law will also tighten rules on vaping and other nicotine products, particularly around marketing and display.
In London, people had mixed views on whether or not they think it will make a difference.
