Here, they find a correlation between e-cigarette use and higher and more sustained levels of smoking. But because this is a cross-sectional study, they cannot determine which came first. In other words, what is the direction of the causal relationship? Does the e-cigarette use precede, and cause, the smoking? Or does the smoking precede, and cause, the e-cigarette use?

I summarize my argument as follows: "In recent years, the tobacco control movement has squandered the opportunity to reduce smoking-related disease and death. Instead of continued progress, the tobacco control movement has largely been co-opted by a bureaucracy of national organizations that seem more concerned about bolstering their funding streams than fighting the tobacco industry. Both the government and the national tobacco control organizations have largely abandoned the fight against the tobacco industry and smoking, and instead have dedicated themselves to seeking funding for research or policy that makes little or no further contribution to the protection of the public’s health."

Clive further shows how the misguided headlines created by Glantz have already led to public policy makers being misled by this misrepresentation of the science.
