> As the mechanism is unknown, it’s unclear what the actual danger is. Is it some byproduct of the nicotine cartidges, or THC ones? Is it the vapor itself? Is it only at certain temperatures or concentrations? Is it directly affecting the lungs or entering the bloodstream? No one knows yet — all they’ve seen is an sudden uptick in respiratory or pulmonary issues where the sufferer also uses vaping products.
We've seen a few studies suggesting certain flavoring agents may cause significant problems, has this been investigated as a possible cause?
- floatingatoll 7y agoAnother vector of harm to consider — Keep in mind that “vapor” is used to disguise that, in all cases whether nicotine or pot or etc, people are heating up a substance to its smoke point and inhaling that smoke. They use “vapor” because it sounds like “water vapor” - which is harmless - but it’s definitely not that. Marijuana cartridges use marijuana oil or MCT oil as a base, for example. Nicotine uses glycol or other substances. We have very little data on consuming glycol and/or MCT oil smoke. It’s possible that it clogs up the lungs in a way that takes hours to heal per inhalation, and so we’re simply seeing smoke inhalation deaths as we would from an oil factory burning for weeks or something. (We have limited data on marijuana extract smoke - cold-processed oil is a new-ish innovation, compared to resin which is high in impurities and not easy to consume in significant quantities like marijuana oil apparently is.)

- refurb 7y agoMy understanding is that unless the vape pen is malfunctioning, it should be burning anything. Your heating it to the point it boils and creates vapor. Not to point it burns.
- adrusi 7y agoThis is incorrect. The solvent is boiled, not burned.
- Varriount 7y agoGlycol, as in ethylene glycol?
- snuxoll 7y agoPropylene glycol.

They use “vapor” because it sounds like “water vapor” - which is harmless - but it’s definitely not that. This is not true. It's producing an aerosol, partially by condensation of vapor produced by heating the glycerine and propylene glycol mixture to its boiling point. It isn't combusting, at least not when everything is working the way that it should, and so is not properly a "smoke".
- mirekrusin 7y agoThere are also “coils” that vibrate to create vapour which happens at room temperature.
- justaj 7y agoThis is interesting. Do you know what this technology is called? I also wonder whether it's more efficient in terms of battery use.
- drankula3 7y agoIt's an ultrasonic vaporizer. Below is a link talking about it. https://youtu.be/aKhPj7uFD0Y https://youtu.be/aKhPj7uFD0Y
- jdietrich 7y ago>Do you know what this technology is called? Ultrasonic atomization. It's used widely in manufacturing for applying thin-film coatings, because it provides a very consistent and controllable spray of very fine droplets. The technology has been applied to vaping by Usonicig, but it's not hugely popular - most people prefer warm vapour.
- nyolfen 7y agowow, this is the first i’ve heard of that for vapes. any recommended reading?
- buildzr 7y agoI'm not a vape guy, but as far as I'm aware no combustion reaction is occurring, essentially it's boiling the substance at a far lower temperature than it would burn. Now, whether glycol and such are good things to inhale is another question but I haven't seen any studies pointing to significant issues with these directly, so I'm hesitant to jump the the conclusion suggested here.
- floatingatoll 7y agoThe conclusion is “we should consider whether propylene glycol inhalation can lead to disorders”, not “we know whether it does”.
- UncleEntity 7y agoPropylene glycol has been used in asthma inhalers and nebulizers since the 1950s. So, probably safe...
- EdwardDiego 7y ago> Propylene glycol has been used in asthma inhalers Do you have evidence for that claim? Because as an asthmatic, I've never encountered an inhaler that contained PG. Apparently it can be used in nebulisers, but unlike inhalers and e-cigs, a nebuliser isn't being used every day.

- floatingatoll 7y agoCorrections below, thanks all! Glad this will be considered by a few people that replied, even if I fail at the precise sciences of it :(
- floatingatoll 7y agoFrom another source on a vaping story, for those who want to follow the thread of concern even regardless of my bad understanding: > One exam, though, picked up something unusual — evidence of abnormal immune cells in his lungs — generally associated with a rare, potentially deadly pneumonia seen in older people who accidentally inhale droplets from oil-based laxatives like mineral oil. https://www.washingtonpost.com/health/one-mans-near-death-experience-with-vaping-related-lung-failure/2019/08/24/ca8ce42c-c5b4-11e9-9986-1fb3e4397be4_story.html https://www.washingtonpost.com/health/one-mans-near-death-ex...
- MiroF 7y agoThis comment is blatantly false within the first few sentences
- Tharkun 7y agoI also remember reading about the heat of the coils causing "nano" copper particles to be released/inhaled, might be a contributing factor.
- dogma1138 7y agoCoils aren’t made of copper afaik, they are made out of steel or any other metal with high resistance.
- jdietrich 7y agoMost modern vaping devices use coils made of 316 grade stainless steel, which has no copper content. Unless you're doing something really stupid, the release of metal particles should be within OSHA limits by several orders of magnitude.
- qes 7y ago> Most modern vaping devices use coils made of 316 grade stainless steel No they don't. SS316 is an option, but not the most common. NI200 is still by far the most common coil material.
- ajurna 7y agoi have to disagree. you're both wrong. the most common in all coils is Kanthal A1. If your building your own coils then NI200 is quite popular atm, but most tank and coil systems use Kanthal.
- madaxe_again 7y agoI vape - I buy only high quality liquids from a reputable manufacturer who extensively test all of their recipes. I find my lung function is 100x better than when I smoked. I did, however, once buy a THC liquid, from a “reputable” dark web dealer. It was bloody awful - found myself retching and hacking for days after a few small tokes, and it destroyed both the coil and the tank - sticky residue, carbon, bleurgh. So... given that the other symptoms mentioned are vomiting and diarrhoea, I think this is going to transpire to be dodgy THC liquids, as this also sounds like Cannabis Hyperemesis Syndrome.
- TomGullen 7y agoMe and my girlfriend exclusively vape vampire vape juices, how do we go about researching if the manufacturer is reputable and test all their recipes?
- ldoughty 7y agoYou read their website and pray they don't lie... The only good way is somehow lucking out and finding an independent researcher that tests them without financial incentive from the company. Otherwise typically the findings will always be on favor because companies request preliminary data and pull funding to continue research if it looks bad so it doesn't get published
- jdietrich 7y agoBuy from a European supplier - testing is mandatory and all e-cigarette products must be registered with the national healthcare regulator prior to sale. It's not an ironclad guarantee of safety, but we have an effective regulatory regime. https://www.gov.uk/guidance/e-cigarettes-regulations-for-consumer-products https://www.gov.uk/guidance/e-cigarettes-regulations-for-con...
- madaxe_again 7y agoThe other thing to do is check out their safety data sheet - means an independent lab has audited them. Vampire Vape, that the GP mentioned, have theirs here: https://www.vampirevape.co.uk/media/safety-data/attraction-0mg-sds.pdf https://www.vampirevape.co.uk/media/safety-data/attraction-0...
