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?
Quality control, especially of cheap vapes
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
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.
I hadn’t considered solder in the tank. No bueno.
Regulatory issues. Adulterants in shitty quality disposables.
Not “vaping inherently dangerous.”
