European Respiratory Review 2018 wrote a good overview:
Cadmium in tobacco smokers: a neglected link to lung disease?
In the first of this three-part series on Vaping-Associated Pulmonary Injury (VAPI), I will introduce a compound with the motive, means, and opportunity to cause the illness. Part 2 will identify the common point of origin linking vape users in the United States and why Europe is unaffected, and, finally, Part 3 will outline a rational harm-reduction based approach for evaluating the safety and continued use of these products.
(We can list 6-14 days for “Onset of symptoms post-exposure” for VAPI, according to the CDC/FDA)
I am not thrilled at the source, considering they don’t seem to be a research lab, and they sell CBD and CBN. But then I read about the founder (below). I hope that this work from Colorado Green Labs gets attention from experts to weigh in on its merits. @MagisterChemist what do you think?
Frank Conrad holds degrees in Molecular Biology, Business Administration, and Biomedical Sciences. He has worked as an analytical chemist and applied scientist in the cannabis industry since early 2014.
Prior to co-founding Colorado Green Lab in 2014, Mr. Conrad was employed as a biochemist in the biofuel industry (2011-2014), and in various areas of academic research and education 2000-2010).
Mr. Conrad and CGL have been instrumental in shaping standards and practices of the Colorado cannabis testing facilities through active engagement with regulatory agencies, industry groups, and by providing educational outreach on the scientific underpinnings and socio-legal impact of cannabis cultivation and use.
The next part of their three part blog is titled Part 2: Vape Pen Vivisection
