Contrasts Between Survey Waves (2017–2020) Within Each Country for Exposure to Mostly Negative News Stories and Perceptions of Vaping Harms, Adjusting for Demographic Covariates.

	Full sample (n = 63 380)						Past 30-day vapers (n = 9 442)
	Exposure to mostly negative news stories about vaping		Accurate perception that vaping is less harmful than smoking		Perception that vaping takes less than a year to harm users’ health		Worry that vaping will damage your health in the future
