For unknown reasons, the FAQ doesn't say whether they've ever tested that all the vitamins and hormones (melatonin) make it intact and unadulterated, in a form the body can work with even though they have not been through the digestive system, to the blood stream. They just say (over and over again) that it is heated to only 120 degrees Celsius. That perhaps will avoid turning the substances into plastics, but even that fairly low temperature is surely enough to chemically alter some, especially more complex, molecules. In fact, that's the exact problem with "popcorn lung" which does come up occasionally on the site. It says there are no oils, but with the plant extracts, they are all essential oils. That's not necessarily a bad thing, but more care needs to be taken in these claims. Have their been any clinical studies of the efficacy of vaporized vitamins and hormones? Were there any long term tests on its effects to the lungs. Merely omitting the "popcorn lung" chemical is not the only thing to concern yourself with (although it is ultra important, as we've seen historically with counterfeit vapes back when vapes were new). What are the effects of each of the ingredients showing up in vapour form, in the lungs where they absolutely normally would not appear? Do they have the ability to impact lung function down the road? What if a person has a lung infection... from minor cold to Covid. Does bathing the invading bacteria or viral matter in what is essentially food affect the severity of the symptoms? (OTOH some of the mint formulations might actually be helpful there... there is a history of vaping mint extracts for that purpose). I'm not being cynical, and I'm not nay-saying the product. On the outset, it seems like a reasonable idea for smokers who are at that last stage of nicotine addiction. I just think they've perhaps glossed over some really important questions.
