Check out this article on the Vaping Post on secondhand vapour from earlier this week.
One case from a California Department of Public Health study into air sampling in vape shops has found that “secondhand vaping” appears to result in minimal exposure of hazardous chemicals to bystanders.
You can find the original blog post by Dr. Michael Siegel which the Vaping Post is commenting on here. As Dr. Michael Siegel says:
Despite the claims of many anti-vaping organizations, the documented health risks of “secondhand vaping” appear to be minimal. And this [the case study] is in an environment with relatively extreme conditions — there was a visible cloud of vapor at times. Based on the current scientific evidence, I fail to see the justification for banning vaping in most public places. And remember, this is coming from a guy who has devoted virtually his entire career to banning smoking in bars, restaurants, casinos, and every other indoor workplace (and even outdoor seating areas of restaurants). So I’m certainly not one to minimize the health risks of preventable environmental exposures.
The UKVIA looks forward to seeing the study in full, and whether this case is representative of the California Department of Public Health’s findings.
