This study aims to determine high school student's knowledge levels and usage patterns concerning electronic cigarettes. This descriptive and cross-sectional study was conducted with 354 high school students studying in a district of Istanbul between September-December, 2025. Data were collected online using a Descriptive Information Form that inquired about individual characteristics and electronic cigarette use. The mean age of the students was 16.14 ± 1.21 years, and 64.4% were female. While 15% of the students reported smoking cigarettes, 59.6% had at least one parent who smoked. Additionally, 69.4% of the students began smoking between the ages of 13 and 15. Electronic cigarette usage was reported by 9.3% of the students, and 25.1% reported considering using e-cigarettes in the future. Only 38.6% of the students were aware of the harms of electronic cigarettes, with most information being obtained from friends, social media, and their environment. Compared to traditional cigarettes, 28% of students disagreed that electronic cigarettes are less harmful, 38.2% disagreed that they are less addictive, and 39% were undecided on whether electronic cigarettes are cheaper. Furthermore, 52.8% of students stated that electronic cigarettes are popular in social settings, while 62.4% believed they are completely harmless. It is recommended that awareness and educational programs related to cigarettes and electronic cigarettes be provided at an early age to raise awareness and inform young people on this issue.
