This study examines factors associated with self-reported addiction to e-cigarette use among this population.Methods In 2018, 1048 Canadians aged 16–25 years were recruited through online social media platforms to complete a survey. Quota sampling was used to oversample regular e-cigarette users (vaping at least weekly); these 578 regular users were included in this analysis. Self-perceived addiction was assessed by asking participants if they felt they were ‘very’, ‘somewhat’ or ‘not at all’ addicted to e-cigarettes. A proportional odds model was employed to identify factors associated with the ordinal outcome.Results Almost half of regular users perceived themselves to be ‘not at all addicted’, 41% felt they were ‘somewhat addicted’ and 13% felt they were very addicted to e-cigarettes. Women, former cigarette smokers, daily vapers and those vaping for more than a year were more likely to report higher levels of perceived addiction. Similarly, high sensation-seeking youth, those reading blogs and websites about vaping, those frequently dripping and those using higher nicotine strengths had a greater likelihood of higher perceived addiction than their respective counterparts.Conclusion More than half of youth and young adult regular e-cigarette users felt they had some level of addiction. The findings identify possible opportunities for targeted programming for education and treatment, as well as potential opportunities for policy change such as maximum allowable nicotine strengths.Data are available upon reasonable request.
