Herbal Cigarettes May Be More Harmful Than Tobacco, New Study Warns

Inn/gandhinagar,@infodeaofficial

For years, herbal cigarettes have been marketed as a “natural,” tobacco-free, and safer alternative to regular smoking. Many brands claim benefits such as stress relief, better sleep, and reduced nicotine dependency. However, a groundbreaking new study by researchers from IIT Gandhinagar and the University of Illinois Urbana-Champaign has challenged these claims, revealing that herbal cigarettes may be just as harmful—or even more dangerous—than conventional tobacco cigarettes.

The findings arrive ahead of World No Tobacco Day, observed annually on May 31 by the World Health Organization (WHO), highlighting the urgent need to address misleading perceptions surrounding alternative smoking products.

Study Finds Higher Toxic Emissions in Herbal Cigarettes

The research compared smoke emissions from two leading tobacco cigarette brands in India and four popular herbal cigarette varieties made from ingredients such as basil, clove, cinnamon, mint, chamomile, green tea, and water lily.

Researchers discovered that herbal cigarettes released approximately 20% more ultrafine particles than tobacco cigarettes. These particles, smaller than 500 nanometers, are linked to serious respiratory and cardiovascular diseases because they can deeply penetrate the lungs and bloodstream.

The study also measured “Oxidative Potential” (OP), a scientific indicator of how smoke particles generate harmful reactive oxygen species inside the body. High OP levels are associated with inflammation, lung damage, and heart disease.

According to the findings, herbal cigarette smoke showed significantly higher oxidative potential compared to traditional tobacco smoke.

Tendu Leaf Wrappers Found to Be Especially Harmful

One of the most alarming discoveries involved herbal cigarettes wrapped in tendu leaves—the same leaves commonly used in bidis, India’s most consumed smoking product.

Researchers found that tendu-leaf-wrapped herbal cigarettes had nearly 49% higher oxidative potential than paper-wrapped variants, making them among the most hazardous products tested.

The study also identified unexpectedly high levels of lead in one herbal cigarette brand containing basil, despite being marketed as “chemical-free” and “100% natural.”

“Natural” Does Not Mean Safe

Professor Sameer Patel from IIT Gandhinagar explained that the findings challenge the widespread belief that tobacco-free products are risk-free.

According to researchers, the harmful effects are not limited to nicotine or tobacco itself. The process of combustion—burning plant materials—creates toxic fine particles, soot, and heavy metals regardless of the ingredients used.

Experts emphasized that smoke inhalation from any combustible product can trigger harmful biological reactions in the body.

How Researchers Conducted the Study

To accurately measure smoke emissions, scientists used a specialized two-chamber automated smoking system designed to replicate human inhalation patterns.

Smoke particles were collected and analyzed in real time for:

• Physical properties
• Chemical composition
• Particle size distribution
• Oxidative toxicity

The comprehensive analysis was published in the prestigious Journal of Hazardous Materials, an internationally recognized peer-reviewed scientific journal focused on environmental and health hazards.

Regulatory Gaps Raise Public Health Concerns

The study also highlighted major regulatory loopholes surrounding herbal cigarettes in India and other countries.

Under India’s Cigarettes and Other Tobacco Products Act (COTPA), tobacco products are subject to warning labels, advertising restrictions, and smoking regulations. However, many herbal cigarettes marketed as tobacco-free may bypass these strict rules.

Researchers warn that wellness-focused branding and “natural” marketing strategies could attract young consumers and first-time smokers who may mistakenly believe these products are harmless.

World No Tobacco Day 2026: Unmasking the Truth

The findings strongly align with the theme of World No Tobacco Day 2026: “Unmasking the Appeal: Countering Nicotine and Tobacco Addiction.”

Public health experts say stronger regulations and evidence-based awareness campaigns are urgently needed to prevent misleading health claims associated with herbal smoking products.

The study serves as an important reminder that “herbal” or “natural” labels do not automatically make smoking safer.

Conclusion

The latest research from IIT Gandhinagar and the University of Illinois provides compelling scientific evidence that herbal cigarettes are not a safe alternative to traditional smoking.

Whether tobacco-based or herbal, smoke generated through combustion contains harmful particles and toxic compounds capable of damaging human health. As awareness grows, experts believe governments and regulatory agencies must take stricter action against misleading marketing practices targeting consumers seeking “healthier” smoking options.
