The Adverse Effects of Concurrent Tobacco and Marijuana Use
A new study by American scientists found that using tobacco and marijuana during pregnancy has significant adverse effects.

According to a report on May 9th from the Journal of Clinical Endocrinology and Metabolism, a new study conducted by American scientists has found that the simultaneous use of tobacco and marijuana during pregnancy can have significant adverse effects on both the mother and the baby, far exceeding the impacts of using each product separately. In particular, the increase in infant mortality rate is most pronounced, with the risk increasing fourfold.

 

This research was conducted by Adam Crosland and his colleagues at the Oregon Health and Science University. They analyzed data from hospital discharge and death records in California from 2012 to 2019, identifying all women carrying singleton pregnancies between 23-42 weeks of gestation for the study. During this period, they found that the prevalence of marijuana use among participants increased from 0.5% to 1.0%, smoking rates decreased from 2.1% to 1.5%, while the proportion of simultaneous users remained stable at 0.3-0.4%.

 

In an analysis of pregnancy outcomes in women, a research team has found that the frequency of hypertension significantly increases in pregnant women who use both tobacco and marijuana. At the same time, there is also an increase in the demand for emergency assistance and the frequency of premature births in these groups. They found that the birth outcomes of infants were more unfavorable. In the combined use group, the infant mortality rate was four times higher than the control group; the neonatal mortality rate and their hospitalization rate in the intensive care unit also increased; at the same time, the frequency of low birth weight in children also sharply increased.

 

Researchers have concluded in their report that using both cannabis and tobacco during pregnancy significantly increases the risks for both the mother and particularly the baby. They advocate for taking these risk factors into full consideration when consulting pregnant women and designing health programs for the prenatal period.

Sweden Threatens EU Tobacco Tax Deal as Nicotine Pouch Duty Dispute Looms Over November 9 Meeting
Sweden Threatens EU Tobacco Tax Deal as Nicotine Pouch Duty Dispute Looms Over November 9 Meeting
Sweden is expected to oppose a European Union proposal to raise minimum tobacco excise duties, Law360 reported on October 26, 2026, citing an EU official. A provisional Council agenda dated October 23 confirms that the tobacco taxation package is scheduled for discussion at the November 9 finance ministers' meeting, where member states will seek a general approach. The proposed reforms would raise minimum taxes on conventional tobacco products and establish EU-wide excise rules for vaping liquids, heated tobacco and nicotine pouches. Sweden supports harmonising tobacco taxation rules but objects to requiring nicotine pouches to bear the same minimum tax burden as certain smoking tobacco products. As EU indirect tax legislation requires unanimous Council approval, Swedish opposition could block the proposal in its current form.

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.
