World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

What I don't get, PG/VG & nicotine + flavor chemicals. How the heck does lead get in there? Afaik its not used in synthesis of any of those things
Lead comes from the device hardware, not the juice. Heating coils, solder, and metal parts shed particles when hot.
The metal coil that needs to get red hot to vaporize the PG/VG.
It's not from the coil, at least in the cases that this article is about, but other parts of the tank. Shitty manufacturing, anyways
Or just another shitty study like the one they did in Oregon where they fired the coils for 60 seconds at a time and literally melted the rigs down before measuring what chemicals off gassed from the smoldering pile of plastic and metal.
Yeah no Chinese ever shoved cancer in the face of consumers for money! Let's trust capitalism on this one.
🙄
You're right China bad therefore junk science and our feelings is the only path to follow. 🙄
If the coil is getting red hot it's not producing vapor anymore. Vapor is just boiled oil and the boiling happens at a lower temperature than red hot by a significant amount, and the whole system is configured that the incoming vape juice cools the coil in the process of becoming vapor. This study is about as significant as noticing that if you set the filter of a cigarette on fire it can produce extra-toxic chemicals. No shit, but that's not how they work.
More bullshit ads for plant based vaping alternatives; cigarettes.
I've wrapped enough coils to know they do in fact get red hot. Ask anybody who built coils how many times they've had to throw away a tank full because they ran it too fast and it burnt.
You trust the disposables to supply enough juice to keep the coil from every getting red hot? You trust the coil to be made of safer metals?
I think you kinda made my point for me, once the cart has hit the temperature at which it releases those chemicals the cart is immediately ruined. This kind of goes to my 'if you burn the whole cigarette including the filter the net result is even more toxic'. I mean, sure, but that's really gross data manipulation.
The ruined coil is if you run it too hot for too long... You're being naive if you think it never runs a little dry and the coils never get red hot.
If you have a tank that exposes the coil from the air hole, just look inside it and see how red it gets from a one second hit.
So it doesn't need to get red hot? And in fact getting red hot is bad for it?
Yes and no. I used to build my own coils for my cloud machine. When you first build it, before putting in cotton you want to get it red hot once or twice. This serves a couple purposes. First it both expand and softens the metal so the loops are separated and the electricity has to go all the way around the individual coils. Second, it burns off whatever manufacturing residue that's left on the wire.
Once you have a wick and juice though, it boils drawing away heat and the coil shouldn't be getting red hot any more.
Man, I miss that first fire of a fresh coil before you’ve wicked it, letting it get red-hot and then pressing it together to solidify the shape. Watching for shorts. On complicated windings it’s always so pretty.
Glad I don’t still consume nicotine, but there were parts of the process I loved.
Yeah, it's meditative sometimes. I look forward to missing it.
Thank you, this is the angle I needed for my brains to get it.
My take; clogged watt-limited dispossible vape doesn't get enough airflow, burns the coil. Still not sure where the lead comes from but I get that might release metals. Thanks!
Countries with low manufacturing standards; historically one would assume China but that's not necessarily the case nowadays
Why is a byproduct of 'regulations' that don't allow them to be manufactured in a place with reasonable safety standards. Its not too different than when the US poisoned the alcohol supply and killed or maimed a bunch of people. All they reported at the time was that alcohol/moonshine is dangerous but it was only because the government made it that way by design not something inherent to the product itself.
The coils don't burn it's the cotton that burns and causes dry hits and burnt flavor.
You're splitting hairs. The coils get red hot on dry wick and it burns. The coils are overheating.
It implies that the heavy metals from the electrical components leech into the e-juice
