I guess it’s a case of “start as you mean to go on” regarding ‘scientific research’ on e-cigarettes. The very first paper I read in 2017 has this in its conclusion:
FDA is required to publicly display information about the quantities of chemicals in cigarettes and cigarette smoke in a way that is not misleading. This information, if paired with information from advertising or FDA disclosures indicating that e-cigarette aerosol contains lower amounts of those same chemicals, could have the unfortunate effect of encouraging smokers to become dual users or increase their existing dual use under the mistaken impression that they are significantly reducing their health risks.
That’s quite a statement to make. Here smokers, don’t go dual use tobacco and e-cigs ‘cos you’re not actually reducing the harms. What a way to start 2017.
