Figure 1.. Rate of Electronic Cigarette (e-Cigarette)– or Vaping–Associated Lung Injury Cases and Prevalence of e-Cigarette Use by State and by State Marijuana Policy
A state was considered to be a recreational marijuana state if it had at least 1 recreational dispensary open in January 2019. Results are robust to considering any state with a recreational marijuana law as of 2019 to be a recreational state. In A and B, brackets represent the range of EVALI cases per million, and dashed lines represent the mean by state marijuana policy. In C and D, brackets represent the 95% CI of each group mean. aP = .003 compared with recreational. bP < .001 compared with recreational.
Figure 2.
Figure 2.. Electronic Cigarette (e-Cigarette)– or Vaping Case Rates vs e-Cigarette Use Rates
Dark gray circles represent recreational marijuana states; orange circles, prohibition states; and blue circles, states that allow medical marijuana and do not have recreational dispensaries. A best-fit line is displayed in blue, with a slope of −0.8 and a robust standard error of 0.9 (P = .36). The gray shaded area denotes the 95% CI. Results are robust to weighting by state population.
