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.
There are ones you can refill, the disposable ones should just be banned altogether.
The ones you could refill were the only game in town at the beginning, only thing I ever used. Need to get back on flower for weed but the cartridges are super convenient, at least they don’t have batteries(I know there are disposable weed vapes, not the same as the cartridges)
