Sir, Rather than a “figment of the imagination” the effect of glitzy cigarette packaging has been scientifically demonstrated (Letters, The Grocer, 8 January)

Previous research has shown that displays have an impact on youth smoking, and evidence from Iceland shows that youth smoking rates fell significantly following a ban.

Contrary to claims from the tobacco industry, recent research showed that retailers in Ireland did not suffer a loss of income when they implemented a ban in 2009. Also, the UK Association of Convenience Stores found the average cost of compliance for retailers in Ireland was just £300.

Despite scaremongering from the tobacco industry, businesses have easily adapted when tobacco displays have been removed. There is no reason why the government should not implement legislation that aims to protect young people from tobacco marketing.
