They may look like travel shampoo bottles and smell like bubblegum, but after a few hundred puffs, some disposable, electronic cigarettes and vape pods release higher amounts of toxic metals than older e-cigarettes and traditional cigarettes, according to a study from the University of California, Davis. For example, one of the disposable e-cigarettes studied released more lead during a day’s use than nearly 20 packs of traditional cigarettes.

Where? Why? Is it a quality control issue or an inherent danger of the technology?

[–] Dasus@lemmy.world 21 points 2 days ago

Regulatory issues. Adulterants in shitty quality disposables.

Not "vaping inherently dangerous."

[–] TimewornTraveler@lemmy.dbzer0.com 9 points 2 days ago* (last edited 2 days ago)

the disposables are the problem. probably manufacturing or regulations. the way the coils aren't changed, the way it sits in it, the way they use highly concentrated nicotine salts... it's nothing like the classic refillable tank and box mods that just took regular juice with nothing but PG/VG/nicotine/flavoring

Chemical composition of the resistance wire

[–] roguetrick@lemmy.world 9 points 2 days ago* (last edited 2 days ago) (3 children)

Could also be due to soldering the resistance wire itself in place, or something else that's in contact with the juice. These guys often ship these in international parcel shipping direct to consumer. That means a lot of shocks and they want to make sure the disposable works when whoever they sold it to(and who clicked "why of course I'm 18) so they don't have to deal with returns. Non disposable vapes do not have solder points in any part of tank or atomizer because they're generally assembled with o rings and threads. These are not.

[–] Gigasser@lemmy.world 1 points 2 days ago

It's adulterants and the solder used. I believe you can access the study through the article itself. It should tell you some of the sources of heavy metals.

[–] rc__buggy@sh.itjust.works 3 points 2 days ago

I hadn't considered solder in the tank. No bueno.

[–] dai@lemmy.world 1 points 2 days ago

I'd be pretty surprised to see lead solder used in these applications, lead free is the defacto standard and has been for a long time. Not in vapes but any consumer electronics device.

More than likely it's the mesh coils used having some lead present.

Quality control, especially of cheap vapes

[–] catty@lemmy.world -4 points 2 days ago (2 children)

People want to ingest a harmful drug and not see that as a threat to their health?

Nicotine isn't really harmful, aside from the rediculously addictive nature it's what a vasoconstrictor?

Much like caffeine it has some decent properties for focus / cognitive abilities.

The main downfall is how it's consumed by the majority of the population. Durries are overall awful. The stench, accidental burns and all the inhaling burning plant matter leading to cancer thing.

[–] Gigasser@lemmy.world 3 points 2 days ago

Nicotine can be bad for your cardiovascular health. It can lead to hardening of arteries over time. Vasoconstrictive effects of nicotine are also really bad for oral health and can encourage development of gingivitis/gum disease, a reminder that loss of gums can be permanent. I vape, been trying to quit, been on and off. It's an insidious habit to kick. I won't discount that it can be good for focus tho, lol.

lobby harder.

Hard to argue with a solid argument such as "lol." You really showed them who's right.

[–] catty@lemmy.world -4 points 2 days ago (1 children)

lol #3

(It was such a stupid statement, one doesn't need to).

[–] CmdrShepard49@sh.itjust.works 1 points 2 days ago (1 children)

Yeah it's totally because everything is "stupid" and not the fact that you have no argument outside of superficial fearmongering which falls apart under the slightest scrutiny. It's so stupid that you keep replying with nonsense talking about how anyone else's statements are unworthy of replying to 🙄

[–] catty@lemmy.world -1 points 1 day ago (1 children)

superficial

You're right. Cancer is superficial damage. Speaking of which, enjoy your cancer.

Nicotine doesn't cause cancer, tobacco does.
