Study simulates ban on cigarette filter holes to see if smokers switch

This study looked at what might happen if cigarette filter ventilation holes were banned. Researchers created a virtual store where 142 smokers could buy different tobacco products at various prices. The goal was to see how smokers would react if only low-ventilated or non-ventilated cigarettes were available. The study did not test any treatment or cure, but aimed to inform future tobacco regulations.
