Smoking is still the primary, causal risk factor leading to COPD, but environmental exposures, such as exposure to biomass fuel combustion, air pollution, and occupational exposures, and poor lung development (both pre- and post-natal) are increasingly recognized as important causes of COPD [3, 12]

Additives are important elements of tobacco products because they allow manufacturers to modify the sensory and pharmacological properties of tobacco products in a way that affects initiation and cessation (with additives that make the smoke less harsh or more pleasant to the user) or bioavailability and impact of nicotine (through changes in smoke pH or through additives such as menthol) (Box 1) [3],[4]
