Meta Title	Vaping in a heavily regulated setting: cross-sectional survey of e-cigarette use, perceptions and social media exposure
Meta Description	Even in a heavily regulated environment such as Singapore's, people appear to be exposed to vaping-related content on social media platforms and this exposure is, in turn, associated with more positive perceptions of vaping, but not e-cigarette ever use.
