What is heated tobacco, and what are its potential impacts on public health

What is heated tobacco, and what are its potential impacts on public health. Heated tobacco refers to a relatively new tobacco product category that claims to provide a reduced-risk alternative to traditional combustible cigarettes. It involves heating tobacco leaves rather than burning them, producing an aerosol that is inhaled by the user. This article aims to explore the concept of heated tobacco, its mechanisms, and its potential impacts on public health. By examining available evidence and scientific research, we can better understand the advantages and potential risks associated with this emerging product.


  1. Understanding heated tobacco: Heated tobacco devices, also known as heat-not-burn products, operate by heating specially designed tobacco sticks or capsules to temperatures below combustion. This process releases nicotine and other volatile compounds, producing an inhalable aerosol. Unlike conventional cigarettes, which burn tobacco and generate smoke containing harmful chemicals, heated tobacco products are claimed to provide a potentially reduced-risk alternative. Some popular brands include IQOS by Philip Morris International and Glo by British American Tobacco.
  2. Potential health impacts: a. Nicotine addiction: Heated tobacco products contain nicotine, a highly addictive substance. Users may become dependent on nicotine, leading to continued use and potential difficulty in quitting. b. Reduced exposure to harmful chemicals: While heated tobacco emits fewer toxic chemicals compared to traditional cigarettes, it still releases harmful substances such as formaldehyde, acrolein, and volatile organic compounds. The extent of risk reduction is a topic of ongoing scientific debate. c. Impact on respiratory system: Inhalation of heated tobacco aerosol can potentially have adverse effects on the respiratory system, including inflammation of the airways and lung function impairment. d. Cardiovascular health risks: Nicotine itself has cardiovascular effects, including increased heart rate and blood pressure. Long-term use of heated tobacco products may contribute to cardiovascular diseases. e. Secondhand exposure: Although reduced compared to traditional cigarettes, heated tobacco products still release secondhand aerosol. Non-users may be exposed to potentially harmful substances, albeit at lower levels.
  3. Regulatory landscape and marketing: The regulation of heated tobacco (NAHŘÍVANÝ TABÁK) products varies across countries. Some jurisdictions classify them as tobacco products subject to tobacco control measures, while others categorize them differently. Regulation typically includes packaging and labeling requirements, advertising restrictions, age restrictions, and product quality control. Marketing strategies employed by heated tobacco manufacturers often highlight reduced-risk claims and target current smokers seeking alternatives. The accuracy and impact of these claims are subjects of ongoing scientific evaluation.
  4. Scientific research and industry influence: Scientific research on heated tobacco products is still evolving. Independent studies are needed to assess the long-term health effects and potential harm reduction compared to conventional cigarettes. However, it is essential to acknowledge potential conflicts of interest, as the tobacco industry funds some research in this field. To ensure unbiased findings, studies should be conducted independently of industry influence.
  5. Youth initiation and dual use: There are concerns that heated tobacco products may appeal to young people due to their novelty and perceived reduced risk. The flavors and marketing tactics employed by manufacturers could attract non-smokers and potentially lead to nicotine addiction. Dual use, the concurrent use of heated tobacco products and conventional cigarettes, is also a concern. It may hinder smoking cessation efforts and maintain nicotine dependence.
  6. Public health considerations and balanced approach: Public health officials and organizations approach heated tobacco products with caution. While they may have the potential to reduce harm for current smokers who switch completely, there are concerns about unintended consequences. It is crucial to strike a balance between harm reduction for smokers and preventing youth initiation and population-wide risks. Public health policies should be evidence-based, employing robust regulation, monitoring, and education campaigns.


Heated tobacco products represent a new category in the tobacco market, claiming to provide reduced-risk alternatives to conventional cigarettes. However, their potential impacts on public health require careful evaluation. While they may expose users to fewer harmful chemicals than traditional cigarettes, the health risks associated with heated tobacco should not be ignored. Independent research and regulation are necessary to assess their long-term effects and prevent unintended consequences such as youth initiation and dual use. A balanced approach that prioritizes public health, evidence-based policies, and continuous monitoring is essential to ensure the potential benefits of heated tobacco products, if any, outweigh the risks.
