Well whatever they're doing is working. The amount of juul pod junk under my feet in my city seems to be growing exponentially year over year. At least cigarette butts are biodegradable! They should be forced to make these things out of cellulose or a similarly biodegradable product as their consumers are going to treat them as butts and just chuck them on the ground when they're done.
It's getting worse now. Disposable vapes are gaining in popularity, and some of those disposable vapes even come with a USB charger (even though they're not designed to be refilled without fluid). This means every time someone is done with the vape, they throw away much larger piece of plastic (compared to Juul pod). When comparing the price-point of a refillable vape (or Juul), disposables are around the same price…
That's only true of the device. JUUL pods contain 2ml and a 4 pack is ~$20, about the same price as a 30ml bottle of juice for refillables.
