Thank you for continuing to educate us. Since reading your articles I've saved a lot of money by not buying from grifters.
I had, for years, believed so much of the hype and regularly purchased products with so many promised results. Glad I've been enlightened with the science.
Thanks for your informative post. Chemophobia is a major ingredient in disinformation in many topics, also by opponents of Tobacco Harm Reduction, making exaggerated claims on the presence of toxic compounds and metals in the aerosols of vaping and heated tobacco products. In this disinformation the mere presence of the compounds (without reference on concentrations or doses) serves as pretext to raise alarm taking advantage of public ignorance. Although these aerosols are not produced by combustion, their heating processes at lower temperatures still produces toxic byproducts, but in concentrations and doses that are, not only orders of magnitude below those of tobacco smoke, but even comparable to those of common household aerosols (cooking, candle lighting, odorizers) and normal indoor pollution.
There are published "independent" studies (NIH funded) that have reported excessive levels above safety markers of metals and organic toxins (specially formaldehyde) in vape aerosols, but all these studies tested the devices in the lab under unrealistic conditions. I can say this with full confidence out of my own published research of reviews of these studies (see references at the end). Recently, a study from UC Davies found high levels of metals (Ni, Sb, Pb) in aerosols of 7 popular unregulated disposable devices, but these aerosols were generated by e-liquids that were already contaminated, most likely by corrosion from long time storage. What all this reveals is that the notion that vape aerosols are too toxic is largely based on low quality studies or misinterpretation of the data (as the UC Davies study).

Unfortunately, this disinformation is very widespread among the public, it has caused harm by preventing millions of smokers to switch to much safer ways to consume nicotine. This misinformation does not come from MAHA or other tricksters, it comes from established USA Apple Pie sources, look at websites of the ALA, AMA, ACS, even in the CDC and FDA. It is propagated by the NYT, WP, CNN and a lot of media.
