It contributes to cumulative exposure to carcinogenic and toxic heavy metals, including cadmium, lead, nickel, and copper. Collectively, these metals promote oxidative stress, multi-organ damage, and an increased risk of cancer, cardiovascular, respiratory, and renal diseases; (2) Methods: The research material comprised 119 tobacco samples. The concentrations of cadmium, lead, copper, and nickel in the samples were subsequently determined. A series of calculations were conducted in order to estimate the non-carcinogenic and carcinogenic health risks associated with the consumption of tobacco products under a variety of exposure scenarios; (3) Results: The concentrations of heavy metals in the tobacco samples ranged as follows, with mean values: Cd: 0.3\u20138.6 mg\/kg (mean 1.0), Cu: 3.4\u201392.6 mg\/kg (mean 12.3), Ni: 1.1\u201315.4 mg\/kg (mean 3.4), and Pb: 0.2\u20131633.3 mg\/kg (mean 46.5). A health risk assessment indicated that exposure through inhalation to cadmium Cd, Ni, and Pb, even in the minimal smoking scenario of one cigarette per day, consistently exceeded internationally established thresholds for carcinogenic risk; (4) Conclusions: The presence of high inter-brand variability and high-risk outliers underscores the necessity for enhanced regulation and monitoring of toxic metals in tobacco products.<\/jats:p>","DOI":"10.3390\/toxics13121088","type":"journal-article","created":{"date-parts":[[2025,12,18]],"date-time":"2025-12-18T11:08:28Z","timestamp":1766056108000},"page":"1088","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Toxic Trace Element Concentration in Commercially Available Cigarettes in Poland, Europe"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4219-9949","authenticated-orcid":false,"given":"Ma\u0142gorzata","family":"\u0106wiel\u0105g-Drabek","sequence":"first","affiliation":[{"name":"Department of Environmental Health, Faculty of Public Health in Bytom, Medical University of Silesia in Katowice, 18 Piekarska Street, 41-902 Bytom, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4471-3147","authenticated-orcid":false,"given":"Joanna","family":"Domagalska","sequence":"additional","affiliation":[{"name":"Department of Environmental Health, Faculty of Public Health in Bytom, Medical University of Silesia in Katowice, 18 Piekarska Street, 41-902 Bytom, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4154-8350","authenticated-orcid":false,"given":"Marta","family":"Buczkowska","sequence":"additional","affiliation":[{"name":"Department of Chronic Diseases and Civilization-Related Hazards, Faculty of Public Health in Bytom, Medical University of Silesia in Katowice, 18 Piekarska Street, 41-902 Bytom, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0564-2849","authenticated-orcid":false,"given":"Agata","family":"Piekut","sequence":"additional","affiliation":[{"name":"Department of Environmental Health, Faculty of Public Health in Bytom, Medical University of Silesia in Katowice, 18 Piekarska Street, 41-902 Bytom, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"143","DOI":"10.1038\/s41568-021-00423-4","article-title":"Smokeless Tobacco and Cigarette Smoking: Chemical Mechanisms and Cancer Prevention","volume":"22","author":"Hecht","year":"2022","journal-title":"Nat.
