Limited data exist on this association in the Indian context. Objectives: To assess the prevalence of oral lesions among young e‑cigarette users and examine usage patterns and risk awareness. Materials and Methods: This is a cross‑sectional study of 300 urban Indians (150 users, 150 nonusers) aged 18–35 years. Participants underwent standardized oral examinations and completed structured questionnaires. Statistical analyses included prevalence ratios (Poisson regression) and Chi‑square tests. Results: E‑cigarette users showed significantly higher prevalence of leukoplakia (9.3% vs. 3.3%, relative risk [RR] = 2.80, P = 0.038) and oral ulcers (8.0% vs. 2.7%, RR = 3.00, P = 0.045), daily users had 2.1 × higher lesion risk (95% confidence interval [CI]: 1.25–3.52, P = 0.005), and only 15.3% of users recognized oral health risks versus 28.7% of nonusers (P = 0.008) . Conclusion: E‑cigarette use was independently associated with oral lesions, demonstrating clear dose–response relationships. Critical knowledge gaps exist regarding vaping risks, underscoring the need for targeted public health interventions  \nKeywords: E‑cigarettes, India, leukoplakia, oral ulcer   \nIntroduction  \nThe rapid proliferation of electronic cigarettes  \n(e‑cigarettes) among young adults in urban India has become a growing public health concern. Marketed as a safer alternative to conventional tobacco, e‑cigarettes have gained popularity due to their sleek designs, diverse flavors, and perceived lower health risks.[1] However, emerging research indicates that e‑cigarette aerosols—containing nicotine, propylene glycol, glycerin, and  \n\n| Access this article online |  |\n| --- | --- |\n| Quick Response Code:\u003Cbr>| Website: [https://journals.lww.com/jpbs](https://journals.lww.com/jpbs) |\n|  | DOI: 10.4103/jpbs.jpbs_1505_25 |\n\nvarious flavoring agents—may contribute to adverse oral health effects, including mucosal irritation, leukoplakia, and an increased susceptibility to periodontal diseases.[2]  \n\n| Address for correspondence: Dr. Nagappan Nagappan, Professor, Department of Public Health Dentistry, Chettinad Dental College and Research Institute, Kelambakkam, Chengalpet - 603 103, Tamil Nadu, India.\u003Cbr>E-mail: [nagappan.dent@gmail.com](nagappan.dent@gmail.com) |\n| --- |\n| This is an open access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 License (CC BY-NC-ND), where it is permissible to download and share the work provided it is properly cited.
