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.

Texas Extends Tobacco Tax Interpretation to a 6-Methylnicotine Product, Citing VELO Ruling
Texas Extends Tobacco Tax Interpretation to a 6-Methylnicotine Product, Citing VELO Ruling
The Texas Comptroller of Public Accounts ruled in September 2026 that a combustible product made with non-tobacco plant material and 6-methylnicotine (6-MN), a synthetic nicotine analog, qualifies as a taxable tobacco product. The applicant said the product contained neither tobacco leaf nor measurable conventional nicotine. The determination applies reasoning from a May Texas Supreme Court decision involving VELO nicotine pouches, finding that the plant material and 6-MN together perform the functions of tobacco in a conventional smoking product. The ruling carries applicable tax, licensing and reporting obligations but is limited to the facts submitted by the taxpayer. It does not establish a blanket tax classification for all 6-MN products or extend the same conclusion to e-cigarettes.

Special Report | How Capital Is Reassessing the Global Tobacco and Modern Nicotine Industry: Lessons from a New York Forum
Capital is reassessing the global tobacco and modern nicotine industry as heated tobacco, vaping and nicotine pouches reshape demand, profitability and regulation. At the 2026 New Approaches Summit in New York, investors and analysts examined whether smoke-free growth can sustain earnings, how regulation shapes startup value, and whether shareholder engagement can be more effective than divestment. The debate points to a broader shift: tobacco transition is increasingly becoming a capital-allocation, governance and valuation question.

India Duty-Free Nicotine Pouch Sales Face Regulatory Test as ZYN, FOX Classification Remains Open
India Duty-Free Nicotine Pouch Sales Face Regulatory Test as ZYN, FOX Classification Remains Open
The Bombay High Court has ruled that airport duty-free shops are not exempt from India's domestic regulatory laws merely because they operate beyond the customs barrier, leaving in place a sales halt covering ZYN and FOX nicotine pouches at Mumbai's international airport. The court, however, did not determine that the products necessarily qualify as "drugs" under India's Drugs and Cosmetics Act. The retailers have four weeks to submit product information to the appropriate authorities, including CDSCO, which must complete its review within 30 days of receiving the submissions.
