Lovely, something I'm dealing with. I work in the industry.
To start with, the FDA is the cause of and utterly failed solution to most of what you've said here. Whatever your opinion on vapes is, the FDA drags their feet incessantly on this in a matter that pretty much tries to hand R.J. Reynolds, Alterion, and that other major company whose name I keep forgetting a monopoly on a market they were late to the game on. China gets on this shit simply because China doesn't have an FDA getting paid to be pissy about everything. It makes everything unironically suck that much harder and really outmoded true refillable devices as most of the good liquids got canned thanks to the fucking FDA. So all else considered, the gayness and waste factors are inflated to some degree thanks to that. Now let's get into the meat of the comment...
They're non-refillable, extremely wasteful...
So there are some more pod and tank-based models out there cutting down on the waste at least somewhat by having a separate battery and liquid system. Foggers are kinda doing this since they split the battery between a reusable thing and the tank, and if regulation wasn't rearing its butt-ugly head in my state I'd be picking up some X-posed devices that do something similar. I get the idea though, but I'd raise that the FDA being fuckups really helped kill the market for refillables for no real good reason.
...there's no way to tell if the chinese liquid you're vaping has fentanyl in it...
There is actually. Fifty Bar is selling themselves as a Made And Filled In America device and has been for a while. We'll see where that goes, but there is an option, and especially with the whole tariff thing going on, they were a good safe-bet for a device that'd stick around. Otherwise, most of the horror stories involved bootleg crap, always check for a QR code on nicotine devices. While there are ways to BS that, so far I haven't heard of it fucking up from distributor to retailer in the pipeline, it's generally retailers doing shady crap.
... and I'm starting to see them as litter on the side of the road.
No defense or comment. This is shitty behavior and people shouldn't do this.
This has to stop. It's a waste of lithium and a charge controller to buy something that you can recharge, that lasts only a week anyway.
This is one of the many reasons I loathe the FDA, because it's encouraging the states to do their jobs in the worst way possible. Puffcount on disposables has gone up quite a lot. Another model of device I was looking at acquiring were Adjust vapes. Aside from the multiple levels of flavor mod to add, they boasted a 40K puff count or something. Absolutely bonkers. Anyone going through that a week is doing some chain-smoking multiple-packs-a-day crap or deliberately running their devices inefficiently.
Disposable products that have lithium batteries inside is insane and I have no idea how that was ever not illegal.
Because the FDA is omega-gay and will defend even worse while trying to tar vaping. I am not kidding when I say the FDA basically made this problem with their dereliction of duty and byzantine PMTA processes.
As far as recommending it or not, none of this crap is healthy, but if you're smoking ciggies, this is healthier relatively speaking. I'd support people doing it if it's at the expense of Big Tobacco, but it's a vice and I'd represent it no other way.
