Natural cigarettes, broadly offered in India and overseas as pure, tobacco-free and even therapeutic options to standard cigarettes, aren’t safer than common tobacco cigarettes. They produce emissions that may be comparably or much more damaging as tobacco smoke.
These are the important thing findings of a brand new joint research by the Indian Institute of Know-how Gandhinagar (IITGN) and the College of Illinois Urbana-Champaign (UIUC), US.
The research in contrast emissions from two of India’s best-selling tobacco manufacturers and 4 common natural varieties containing mixtures of basil, clove, cinnamon, mint, inexperienced tea, water lily, and chamomile. Notably, two of the natural manufacturers utilised tendu (ebony) leaves as wrappers, equivalent to these utilized in bidis, India’s most generally consumed smoking product.
On the event of World No Tobacco Day, noticed by the World Well being Group and different stakeholders, it’s crucial to create consciousness that Natural Cigarettes Are Not Safer Than Tobacco. Every year on Might 31, WHO collaborates with governments, well being organisations, civil society and youth to finish the tobacco epidemic and safe a tobacco- and nicotine-free future for the subsequent era.
The findings have been revealed within the Journal of Hazardous Supplies (https://doi.org/10.1016/j.jhazmat.2026.142424), a peer-reviewed, high-impact worldwide journal that publishes analysis on era, remedy, administration and environmental affect of hazardous substances and pollution. The paper was co-authored by Alok Kumar Thakur and Sameer Patel from IIT Gandhinagar and P.S. Ganesh Subramanian and Vishal Verma from the College of Illinois, Urbana-Champaign, US.
The analysis paper presents a complete comparability of the bodily, chemical, and oxidative properties of mainstream (firsthand) smoke from commercially out there natural and tobacco cigarettes within the Indian market.
Elaborating on the important thing findings, Prof Sameer Patel, Assistant Professor, Division of Civil Engineering and Chemical Engineering, IITGN, and co-coordinator of the Dr Kiran C Patel Centre for Sustainable Improvement, IITGN, mentioned, “Our findings problem the broadly held perception that tobacco-free means risk-free. Emissions from natural cigarettes are akin to or exceed these from tobacco cigarettes on practically each metric we measured. Leaf-wrapped natural variants turned out to be probably the most hazardous of all of the samples examined.”
To isolate the emissions, every cigarette was combusted inside a sealed, automated two-chamber rig designed to copy human inhalation fee. The cigarette emission was funnelled into real-time devices, and filter samples have been collected for bodily and chemical characterisation of particles. As a proxy for the potential toxicity of emissions, the oxidative potential of the collected samples was quantified.
A key discovering was that sub-500-nanometer particles have been emitted at roughly 20 per cent increased concentrations in natural smoke than in tobacco smoke. These tremendous particles are more and more linked to cardiovascular and respiratory illness.
The group additionally measured a property referred to as ‘Oxidative Potential’ (OP), which quantifies the smoke’s capability to generate reactive oxygen species, aggressive molecules that drive irritation, lung tissue remodelling, and the vascular adjustments underlying coronary heart illness. Particulate matter from natural cigarettes recorded considerably increased OP than that from tobacco cigarettes.

Tendu-leaf-wrapped variants, specifically, confirmed OP roughly 49 per cent increased than paper-wrapped variations. Apparently, chemical evaluation revealed one natural cigarette, stuffed with basil, had the best lead focus, regardless of being marketed as “chemical-free with 100% pure filler for a wholesome way of life.”
Prof Vishal Verma, analysis collaborator and an Affiliate Professor of Environmental Engineering, within the Division of Civil and Environmental Engineering, College of Illinois Urbana-Champaign, U.S., added, “That discovering is vital as a result of many shoppers affiliate nicotine-free merchandise with diminished hurt.”
‘REGULATORY GAP’
The research additionally lays naked the regulatory hole downside surrounding natural cigarettes. India’s Cigarettes and Different Tobacco Merchandise Act, 2003 (COTPA) regulates tobacco merchandise by way of warning labels, promoting restrictions, and public-smoking guidelines, however merchandise marketed as tobacco-free usually fall outdoors these frameworks. Comparable regulatory gaps exist in a number of different nations.
Based on lead writer, Dr. Alok Kumar Thakur, a number of of the natural cigarettes they examined have been marketed with claims of relieving cough, bettering sleep, or easing anxiousness. “Nevertheless, there may be restricted scientific proof evaluating the emissions and toxicological impacts of those merchandise,” he added.
Dr Thakur accomplished his PhD at IITGN as a Prime Minister Analysis Fellow and is presently pursuing postdoctoral analysis at Colorado State College, U.S.
The researchers emphasise that the research doesn’t make direct epidemiological claims about illness outcomes. As an alternative, it focuses on measurable properties of the emitted smoke particles and their potential organic reactivity.
“Combustion, tremendous particles, soot, hint metals, and the wrapper round all of them matter greater than what’s written on the field,” mentioned Dr PS Ganesh Subramanian, presently a postdoctoral researcher at Washington College in St. Louis, US.
The paper’s findings coincide with the theme of World No Tobacco Day on Might 31, “Unmasking the attraction: countering nicotine and tobacco habit.”
With the natural cigarette class probably attracting youthful shoppers and first-time people who smoke utilizing wellness-oriented language, there may be an pressing must develop frameworks to manage the advertising and marketing of tobacco options. This research provides to a rising physique of scientific proof that would assist inform evidence-based regulation and public-health discussions round different smoking merchandise.
