Most people who take up cigarette smoking, and place themselves at greater risk of cancer and lung ailments, start when they are young. A new RAND Corporation analysis finds the answer may be as simple as hiding them.

The scholars created a laboratory replica of a convenience store to examine whether limiting displays of cigarettes in retail outlets can reduce the intention of young people to begin smoking. Researchers found an 11 percent reduction in cigarette smoking susceptibility when the tobacco 'power wall' was hidden compared to when the display of tobacco products was visible behind the cashier.  

Power walls at point-of-sale retail locations display hundreds of tobacco products along with branded posters, product slogans and prices. Power walls are usually positioned behind the cashier. In the current study, researchers created a power wall consistent with what would normally be found in a typical convenience store.

In recent years, the tobacco industry has shifted most of its advertising from places such as magazines and billboards to point-of-sale advertising in retail locations. Canada and several other countries have enacted laws requiring that the power walls be hidden from view and only customers of legal age may view tobacco products.

For the study, researchers had teens visit a replica of a convenience store to do shopping while the tobacco power wall was in one of three random locations: behind the cashier, on a sidewall away from the cashier or hidden behind a screen.

A total of 241 adolescents aged 11 and 17 participated in the study. The teens were told the study was looking at adolescent convenience store shopping habits. The teens were enrolled in the study regardless of past tobacco use.

After completing a pre-shopping questionnaire, the teens were randomized to one of the three experimental conditions and given $10 to spend in the store any way they wanted. The convenience store is 1,500 square feet and is stocked with more than 650 products.

Teens filled out a post-shopping experience questionnaire to determine their attitude toward smoking and their susceptibility to future smoking. The susceptibility assessment included three questions: "Do you think you will try a cigarette anytime soon?" "Do you think you will smoke a cigarette anytime in the next year?" and "If one of your best friends offered you a cigarette, would you smoke it?"

Researchers found hiding the tobacco power wall significantly reduced teenagers' susceptibility to future cigarette smoking compared to leaving the tobacco advertising visible. Moving the power wall to a less-obvious location did not have any effect.
