Disposable vapes may be more toxic than cigarettes, study finds (archive.ph)

I've been saying for years they're gonna find some new and strange way vapes are worse for you than cigarettes

Some popular disposable e-cigarettes emit toxic metals at levels that surpass those found in traditional cigarettes and earlier generations of vapes, according to a new study by researchers at UC Davis.

The study, published Wednesday in ACS Central Science, found that a single day’s use of one disposable device released more lead than nearly 20 packs of conventional cigarettes.

Researchers also identified hazardous concentrations of nickel and antimony — metals linked to cancer, nerve damage and respiratory illness — in the aerosol emitted by seven devices from three widely used disposable vape brands.

“Our study highlights the hidden risk of these new and popular disposable electronic cigarettes — with hazardous levels of neurotoxic lead and carcinogenic nickel and antimony — which stresses the need for urgency in enforcement,” Brett Poulin, assistant professor of environmental toxicology at UC Davis and the study’s senior author, said in a statement.

Using a lab device to simulate 500 to1,500 puffs per product, the UC Davis researchers found that metal concentrations increased with use. Leaded bronze components and degrading heating coils were identified as major sources of contamination.

“When I first saw the lead concentrations, they were so high I thought our instrument was broken,” lead author Mark Salazar said in a statement.

Four of the devices emitted nickel and lead at levels surpassing safety thresholds for neurological and respiratory damage. Two exceeded cancer risk limits due to antimony content.

Disposables are so conceptually gross to me too. Like a whole ass battery in plastic, designed specifically to be thrown away after use??

Especially because you can get a refillable/rechargeable for like $20.

Regardless I quit a couple years ago because I still don't trust regularly inhaling anything as unregulated and unstudied as juice seems to be.

Probably gonna start using patches again because I'm desperate for something that helps with unmedicated adhd

I feel this. Every time I buy one I’m like “well if it’s disposable then it’s easy to quit!” edgeworth-smug Also for that little adhd dopamine too-off (which is such a struggle). I just got a little aromatherapy inhaler thing, and am hoping it’ll help - the hand to mouth action is such a stim for me, and this makes me feel like an essential oil girly 💅

That's a good point, the inertia of not wanting to throw away my nice vape definitely made it harder to quit a few times lmao

You could also try chewing your fingers off like I do

In all seriousness best of luck! I unironically got some heavy metal fidget spinners and learned a couple pen-spinning tricks. Between them they're like 20% effective wrt the hand to mouth stimulus seeking

I might try an aromatherapy inhaler and see if I can placebo myself into thinking it's super potent focus drugs

I’ve been a little over a year without nail chewing for the first time in my life! But yeah I got a “don’t smoke” oil for it that’s basically black pepper and menthol, so it gives that good burn 😂
