here's a transcript from the timestamp until almost the end. The ending has to do with Dutch changing classification of eliquid from class one, hazard, to class three 'toxic' and Dr. F. believes it's mostly a propaganda ploy for political purposes but I was tired, so I skipped it. But here it is from the timestamp:
Q: regarding the use of new metals - new breed of coil turning up made of titanium? - Dr F: Titanium is probably one of the safest options because you avoid nickel and chrome which are not really good, but, ah, there is a potential issue with the development of titanium dioxide. Titanium dioxide may be developed and cover the metal coil during the first few activations of heating cycles but we're not sure if this is emitted to the air. Because that's what's important. The important thing is whether you're seeing titanium dioxide coming into the vapor. Also for the other metals, the important thing is whether chrome from the coil goes to the vapor or whether nickel from the coil goes to the vapor, and I suspect they are. Once again, I want to suggest and advise everyone not only the simple vapers but also the people who are doing the reviews of these cigarettes. Do not overheat the coils. It's one of the worst things that you're doing is to burn the coil until it's getting red. Just in order to fix it, to tighten the wraps, to make them, whatever, to see if the heat transfer is homogenous between the coil wraps. It's the most disasterous things you are doing. Because when you are heating the metal to the point that it's getting, where it's glowing red you are basically destroying the bonds between the metal molecules and then you are greatly facilitating the emission of metals from the coil into the vapor. It's the worst thing that you can do. And I've see every single reviewer doing the same thing over and over and over again. You are destroying the metal structure. Period. Just by doing it once you are destroying the metal structure. You shouldn't do it. If you want to clean the coils because there maybe there some oil from the production process and so on, go use water, alcohol, before even, before preparing the coil itself, Just when you're taking it, when you're cutting it from the roll. Just use water or any alcohol. I would even say acetone you can use it and of course clean it with water, but don't overheat it to the point where it's glowing red. It's the worst thing that you are doing. You're completely destroying the metal structure.
Q: Isn't Kanthal good up to 1500degrees before it starts to go a bit funny ? Dr. F: Before it starts melting? You don't have to melt it to destroy it. It happens a lot earlier...(Dryburning) may be convenient way to make the coil better ,but you're destroying the structure of the metal - there's no doubt about it.
Q: question about Organic liquids?: Dr. F: "In my opinion someone needs to be concerned about something in relation to flavors. The first thing you should be worried about is organic flavors and organic extracts. There's a simple reason. Many people think that organic extracts are natural products so they're much better. Well they're much better to eat them but they're not at all better to inhale them. Because all these extracts have been made to be ingested and the extracts contain a lot of other chemicals besides the flavoring molecules that you are also inhaling. Perhaps they may nutritious or good to ingest them. But, for example, when you have a lot of proteins coming out from a plant where you create a natural extract it's not a very good idea to inhale proteins, long chain amino acids and so on. It's not a good thing. And I think that if we want to, if we're about to worry about some of the flavorings the first thing we want to look at is organic flavorings. I'm not saying they're all bad, I'm saying it's an issue of concern. It's something that they said, that they have said, two years ago, it's not something new. We don't have data, we cannot say don't use them, we cannot recommend anything based on evidence but we have reason to think that not all of them but perhaps some of them may be problematic.
Q: Nickel coils? Dr. F: Nickel is a well known toxic chemical, toxic metal, like chrome is nickel, like chrome is in kanthal. The thing is whether any nickel emitted to the aerosol from the coil and it seems from the studies published up to now that some is emitted but there are no studies evaluating nickel coils by themselves. So We don't know. Because the thing it's not what the coil is made of, the thing is if you're getting anything in the aerosol from the coil. Otherwise, If it stays on the coil it doesn't matter.... In any case, the coils, as I have said probably one and one half years ago, is one of the big unknowns. But it's a pity. Because we could study and we could find what is the best coil or two or three options and we could choose. And it would be easy for the industry to follow and it would be cost effective and it wouldn't cost anything basically because going from one coil to the other doesn't make a difference in price. But...
Q what about ceramic discs?: Dr F: It might probably be better because at least you are covering the coil and you don't have a direct contact between the liquid and the metal. You know the metal also acts as a catalyst and actually aids in oxidation of the liquids and the components. But I think that there was some issues with the low rate of temperature elevation. You need a lot more time to heat the liquid and evaporate it, because of course you ceramic acts as an insulator, so I think that's why they weren't used on a broad basis.
Q: what about lungs absorbing vitamins from eliquid? Dr. F: We don't know if they (the lungs) are or not, but that means we don't know if they can absorb or not. But I think they are not made to absorb vitamins or anything like that. And moreover, I don't see a reason for anyone to take vitamins unless they have a specific vitamin deficiency. I think the food supplement industry is worse-regulated than the non-regulated cigarette industry. There some major issues there and I don't see a point in inhaling more and more stuff whether it's vitamins or whatever stuff they think, and it's still unproven whether you're getting anything. (Caffeine) is a stimulant, it's not a vitamin, it's something different, and still we don't know how caffeine is absorbed. I know there is some other inhaler stuff containing caffeine and we still don't know how much is absorbed.
Q: PG safety study of 1947? Dr. F: They evaluated in primates, in monkeys, I think, for 18 months, the effects of breathing air fully saturated with PG and they found no adverse effects.
Q: Opinion on Additives?; Dr. F: Let's not forget that the e-cigarette is used as a smoking substitute. Now I don't see a reason why we should start adding things which basically don't have any effect as a smoking substitute. And I don't recommend making the eliquids more complicated than they are. There's no reason. I don't think that by adding a vitamin it will be better to get you off smoking. Will it? I suppose not.
Q: Large proportion (60%) who use ecigarettes go back to cigs after 3 months - is this a trend? Dr. F: Unfortunately for the majority of people ecigarettes don't work. For smokers I mean. It would be interesting to understand the reasons why they don't work. What kind of devices are they using? Are they willing to use any new generation devices? It's a matter of the efficiency of the devices. We know that not all devices are equally effective. And of course, we know, that cigalikes don't really work. Moreover, the smokers need to understand they may have to try different type of liquids or even a different device before they find some thing that fits their own preference. So if the smoker is not educated basically and he thinks that the ecigarette is another type of tobacco cigarette, get a pack, get a light and that's it, of course you will be disappointed. So they need to be educated. The ecigarette unfortunately is much more complicated than the tobacco cigarette. So, without being educated to know what to expect and to know how you should approach the product, most likely it will fail... There are many people who are using cigalikes who don't even know there are other devices out there. They don't search on the internet they don't care to search on the internet, they just go to the store or the supermarket and get what is there....
Q. About diacytl in liquids? Dr. F: My advice is that people should know, so that people who don't want to inhale diactyl, they should know what liquid contains diactyl. So let the consumer decide for himself. It is very very irresponsible behavior to have the manufacturer decide for you what you're going to vape and to trick you because diactyl has better taste than the substitutes. That's very interesting. But you should mention that there is diactyl, and then we're going to see how many are going to vape it. If someone wants to vape it knowing there is diactyl inside, let him do it, I don't mind at all. But what about me, who don't want for example to vape diactyl, why shouldn't I know? So, if you want to put diactyl in your liquid, ok, as a manufacturer, mention it, so I can have the right to choose. It's simple.
Enjoy!
