Additives may induce adverse health effects,
since they increase attractiveness of consumption of the highly
toxic and addictive tobacco products. Moreover, upon burning
tobacco, some additives are transformed into toxic or even
addictive combustion products. The most commonly used additives are
flavors, such as vanilla and cocoa, followed by humectants. The
Dutch law requires tobacco manufacturers (and importers) to submit
for each tobacco product all additives, including the quantities,
functions and health effects, on a yearly basis.
The number of additives used per tobacco
product type over the years has particularly increased in cigars
(20%) and pipe tobacco (40%). Some cigars contain additives similar
to those used in cigarettes. Additionally, in most cases, these
cigars have cigarette-like characteristics, such as low tobacco
weight and filters. Increase in attractiveness may be the reason of
little cigars and cigarillo’s gaining worldwide popularity.
The additive composition of cigarette brands
remains constant and does not change much over the years. However,
additive composition is different between small and large cigarette
manufacturers. The humectant propylene glycol, for example, is
added by small and large manufacturers in different amounts.
