The main grounds for dismissing the case was that federal law takes precedence; the judge ruled that, as long as products carry the federally-mandated warning about nicotine being addictive they meet legal requirements. Interestingly, he also dismissed a claim about “ultrafine particles”. The idea that e-cigarette vapour is loaded with deadly “ultrafine particles” originates from Stanton Glantz, a former aeronautical engineer who’s notorious for his hatred of vaping, but has been widely dismissed by health experts. The judge said this argument is “far too cursory” to base any legal claims on it.Harris has been given leave to amend his case, and is almost certain to ring it up in court again; he has substantial backing from anti-vaping groups and predatory lawyers. However, the US political scene is changing and the high tide mark of prohibitionism could have been reached.
