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.

New Zealand Associate Health Minister Casey Costello Warns on Illicit Cigarettes as Legal Tobacco Sales Halve Over Decade
New Zealand Associate Health Minister Casey Costello said legal tobacco sales in the country have fallen by more than half over the past decade, with sales declining more than 20% in 2025 compared with the previous year. She warned that the decline may not fully reflect lower smoking rates, as increased availability of illicit cigarettes could also be contributing. The government said it would continue strengthening tobacco and vape retail enforcement while monitoring the impact of illicit tobacco on public health and tax revenue.

China’s Zhengzhou Tobacco Research Institute develops end-to-end heated tobacco analysis to trace aerosol compound origins
The Zhengzhou Tobacco Research Institute of China National Tobacco Corporation has filed a patent application for an end-to-end method to analyze the migration and transformation of chemical compounds in heated tobacco products. Using GC-Orbitrap/MS non-targeted analysis, the method compares tobacco substrate and aerosol samples to distinguish compounds transferred directly from the substrate from those newly formed during heating, while also calculating transfer rates. In an example involving nine heated tobacco products, the patent identified 17 newly formed thermal decomposition compounds and 38 transferred compounds.

BAT New Categories Revenue Rises 18% in H1 2026 as Broad Portfolio Offers More Ways to Win—and Lose
British American Tobacco’s New Category revenue rose 18% at constant rates in the first half of 2026. Nicotine-pouch brand Velo expanded rapidly, while Vuse recovered as U.S. enforcement against illicit e-vapor products strengthened. Heated-tobacco platform glo remained under pressure, and cigarettes continued to provide most of the group’s profit and cash. Compared with PMI and JT, BAT has more routes to growth—but also greater regulatory, investment and execution risks across its broader portfolio.

UK PM Andy Burnham Reshapes Vape Retail Rules as Licensing Could Raise Barriers for New Shops
UK Prime Minister Andy Burnham is pushing a high street reform agenda that could give local authorities greater powers over commercial activity, including vape retail. The reforms could involve expanded planning powers and a potential vape retail licensing system, allowing councils to play a larger role in store locations and market access. The measures are part of the UK’s broader shift toward tighter vape regulation, although no nationwide vape retail restrictions have yet been implemented.
