PMI Pushes Smoke-Free Business in Latin America as Argentina Lifts Heated Tobacco Ban, Mexico City Share Tops 7%
PMI Pushes Smoke-Free Business in Latin America as Argentina Lifts Heated Tobacco Ban, Mexico City Share Tops 7%
Philip Morris International (PMI) showcased IQOS heated tobacco systems and nicotine pouch products at Technovation 2026 in Buenos Aires on October 7–8, presenting research on consumer attitudes, regulatory developments and illicit cigarette trade across Latin America. PMI Chief Global Growth Officer Stefano Volpetti said smoke-free products accounted for more than 7% of the Mexico City market. Argentina repealed its heated tobacco ban in May 2026 and introduced registration requirements for tobacco and nicotine products, while local media reported nicotine pouch sales in Mendoza. A PMI-commissioned survey found that only 8% of respondents across four Latin American countries were familiar with nicotine pouches. A separate KPMG study estimated illicit cigarette consumption at 77 billion sticks across 11 markets in Latin America and Canada in 2025.

JUUL Purchasers Ask Ninth Circuit to Preserve Antitrust Classes in Case Over Altria’s $12.8 Billion Investment
JUUL Purchasers Ask Ninth Circuit to Preserve Antitrust Classes in Case Over Altria’s $12.8 Billion Investment
Private antitrust litigation stemming from Altria's 2018 $12.8 billion investment for a 35% economic interest in JUUL is advancing before the U.S. Court of Appeals for the Ninth Circuit. Direct purchasers, indirect purchasers and indirect resellers of JUUL products filed answering briefs this week seeking to preserve class certifications granted by a California federal court in February. Altria and JUUL argue that individual consumers and large distributors differ too much in purchasing terms to remain in a single direct-purchaser class, while a separate dispute concerns whether California antitrust law can apply to indirect purchasers across 27 jurisdictions. A September trial has been put on hold during the appeal.

China Tobacco Hubei explores staged nicotine pouch delivery, using dynamic membranes to slow early release and gradient particles to sustain later delivery
China Tobacco Hubei explores staged nicotine pouch delivery, using dynamic membranes to slow early release and gradient particles to sustain later delivery
China Tobacco Hubei Industrial Co., Ltd. disclosed several oral nicotine-related patent applications in August 2026, including two that approach staged nicotine release from different directions. One uses a high-viscosity membrane that forms inside the pouch after contact with saliva to slow rapid early release, while the other uses gradient particles with a faster-disintegrating outer layer and a slower core to create a fast-to-sustained release profile. Together, the filings explore how nicotine pouches could balance initial delivery with release later in use.
