Unmasking Toxicity: An In-Vitro Analysis of Harmful Constituents in Smoked and Smokeless Tobacco Products

Background and Objective: The World Health Organization document released on World No Tobacco Day, 2020, mentions that tobacco kills over 22,000 people worldwide every day either from its direct use or second-hand smoke exposure, which is one person every 4 seconds. The objective of this study was to assess and compare various harmful chemicals, mainly nicotine, ammonia, and fluoride, and physical properties such as moisture, pH, present in locally available different types of tobacco products. Materials and Methods: Commercially available tobacco products were taken into consideration based on their popularity and widespread use among the people, and of those, tobacco samples were randomly selected. Laboratory tests were performed to estimate harmful chemicals, mainly nicotine, ammonia, fluoride, and physical properties such as moisture, pH present in tobacco to assess its potential health risks and toxic effects on the human body. Results: Miraj, a special tobacco brand, reported the highest moisture content with a mean value of 44.14. The Mawa tobacco brand sample reported the highest pH (alkaline) with a mean value of 11.65. While the Gudang Garam Cigarettes brand sample reported the lowest pH (acidic) showed a pH of 4.65. Fluoride content was found to be highest in the Gaichap tobacco sample with a mean value of 4.5. The highest nicotine content was found in the IPCO creamy snuff brand with a mean value of 30.92. Ammonia concentrations were highest in Photo Brand Panjabi Snuff and Sable Beedies yielding a mean value of 1.65, followed by Marlboro Cigarettes, IPCO Creamy Snuff, and Miraj Special Tobacco with a mean value 1.06. Conclusions: The study reveals wide variation in harmful chemicals and physical properties among commercial tobacco products. IPCO Creamy Snuff and Miraj Tobacco exhibited especially high levels of nicotine, ammonia, and moisture, raising concerns about toxicity and addiction. Elevated fluoride and extreme pH in some brands suggest risks to oral and systemic health. The findings emphasize the need for tighter regulation, standardization, and greater public awareness to mitigate health impacts and support tobacco control efforts.
