Objective: Although Brazil became the first country worldwide to ban the sale of all tobacco products with any additive that could alter their flavours and tastes in 2012, its implementation was effectively halted by tobacco industry lawsuits, including a constitutional challenge filed in the Federal Supreme Court in 2013. This study aimed at examining, for the first time in the country, the evolution over time of the new registrations of tobacco products with additives that would have been banned if not for the tobacco industry's interference ('counterfactual scenario').

Methods: We used the newly available public database on the registration of tobacco products developed by the Health Regulatory Agency (from 2008 onwards).

In a country whose indicators of population impoverishment continue to increase, it is concerning that individuals spend money to buy cigarettes instead of using this resource in actions that strengthen aspects of the well-being of their lives and that of their families. Based on the Brazilian National Health Survey conducted in 2019, the influence of spending on manufactured cigarettes on the family budget in households with at least one smoker was estimated, stratified by sociodemographic characteristics. Brazilian smokers allocated around 8% of their average per capita monthly household income to the purchase of manufactured cigarettes.

The tobacco industry continues to present the illicit trade of tobacco products as a reason to slow, stop, or reverse tobacco control efforts in Latin America, including increasing tobacco excise taxes. In most cases, industry estimates of illicit trade, usually non-transparent and flawed, dwarf those of independent, rigorous research. Often, independent studies find that the levels of illicit trade are mostly non-consequential or easily manageable (<12%).

Environmental impacts are currently linked to smoking cigarette behavior, as cigarette butts (CBs) represent the most common litter item in natural areas. Despite this, even the best ranked Brazilian cities, in terms of urban cleaning, have no information about urban littered CBs. Thus, CBs were monitored in Santos and Niterói cities, aiming to assess contamination, Cigarette Butt Pollution Index (CBPI) and the illegal market size.

Most Latin American countries have signed and ratified the FCTC, although implementation has been uneven. Countries across the region were relatively quick to adopt mandatory smoke-free workplace policies, but regional progress in other areas has been slower. In taxation, for example, Uruguay and Brazil have made considerable progress while Paraguay and Bolivia have relatively weak policies.

The illicit trade of tobacco products, by enabling access to cheaper cigarettes, favors smoking initiation and hinders its cessation, minimizing the effects of price policy and taxes on reducing the demand for tobacco. This is especially the case among populations with lower income and schooling, where smoking is concentrated. Its confrontation requires multisectoral actions, aligned with the World Health Organization Framework Convention on Tobacco Control, supported by estimates of the illicit trade magnitude and the analysis of its characteristics.

The tobacco industry normally overestimates the illegal market's size in order to reinforce the idea of its direct relationship to the choice to increase taxes by the internal revenue administration. In Brazil, the last increase in taxes on tobacco products was in 2016. The growth of demand for illegal cigarettes has other macrosocial determinants that the industry does not take into account, such as the increase in the economic capacity to purchase legal cigarettes.

Objective: To cross-validate estimates of the size of the illicit cigarette trade based on the results of four different survey methods.

Methods: In 2018/2019, four non-industry-funded, large-scale studies were conducted in selected Brazilian cities: packs discarded in household garbage/PDG (1 city), packs littered in the streets/PLS (5 cities), a phone survey of tobacco users' purchase behaviors/VIGITEL (5 cities), and a face-to-face household survey of tobacco users' purchase behaviors/FTF-household (2 cities). The proportions of illicit cigarettes consumed were based on the price paid by smokers in their last purchase (VIGITEL or FTF-household) and/or direct observation of brand names and health warnings (PDG, PLS or FTF-household).
