Higher e-cigarette disposable prices appear to be associated with reduced e-cigarette use among adolescents in the US, according to a recent study. Researchers evaluated a cohort of 24,370 middle- and high-school students participating in the Monitoring the Future Survey in 2014 and 2015. They examined self-reported e-cigarette use over the last 30 days. Average quarterly cigarette prices, e-cigarette disposable prices, and e-cigarette refill prices were constructed from Nielsen retail data (inclusive of excise taxes) for 50 US markets. They found:
- In a model with market fixed effects, it was estimated that a 10% increase in e-cigarette disposable prices is associated with a reduction in the number of days vaping among e-cigarette users by approximately 9.7% and is associated with a reduction in the number of days vaping by the full sample by approximately 17.9%.
- Refill e-cigarette prices were not statistically significant predictors of vaping.
- Cigarette prices were not associated significantly with e-cigarette use regardless of the e-cigarette price used.
- However, in a model without market fixed effects, cigarette prices were a statistically significant positive predictor of total e-cigarette use.
