Initial Cross-over Test of a Heat-not-burn Tobacco Product to Aid in Switching From Combustible to Noncombustible Nicotine in Smokers

A novel heat-not-burn tobacco product (IQOS) will be provided to smokers, compared against a (cigarette) smoking as usual period in counter-balanced order in a cross-over design.
