Background: The use of high-nicotine content e-cigarettes (so-called pods, such as Juul) among adolescents raises concerns about early onset of nicotine addiction. Methods: In this analysis of adolescents surveyed from April 2017-April 2018, we compare survey responses and urinary cotinine of pod vs. non-pod using past-week e-cigarette users aged 12-21. Results: More pod users categorized themselves as daily users compared to non-pod users (63.0% vs. 11.0%; p = 0.001); more pod than non-pod users had used e-cigarettes within the past day (76.2% vs. 29.6%; p = 0.001). More pod users responded affirmatively to nicotine dependence questions (21.4% vs. 7.1%; p = 0.04). Urinary cotinine levels were compared among those responding positively and negatively to dependence questions: those with positive responses had significantly higher urinary cotinine levels than those responding negatively. Conclusions: Adolescents who used pod products showed more signs of nicotine dependence than non-pod users. Pediatricians should be vigilant in identifying dependence symptoms in their patients who use e-cigarettes, particularly in those using pod devices.
