Results: Regardless of frequency and intensity, smoking was more likely to increase suicidal ideation and attempts than non-smoking. Among smokers, intermittent heavy smokers (suicidal ideation: Adjusted Odds Ratio [AOR]: 1.406, 95% Confidence Interval [CI]: 1.015~2.161, p=.012; suicidal attempts: AOR: 2.977, 95% CI: 1.814~4.886, p<.001) or daily heavy smokers (suicidal ideation: AOR: 1.274, 95% CI: 1.017~1.596, p=.035; suicidal attempts: AOR: 1.717, 95% CI: 1.250~2.359, p=.001) had significantly higher odds of suicidal ideation and attempts than intermittent light smokers. Conclusion: Based on the results, smoking prevention and cessation are essential to preventing suicides in adolescents. Especially, smoking intervention programs are needed to reduce smoking intensity in smokers.
