Is this actually disposable if it has the rechargeable battery and display? Or is it maybe like a lighter that technically can be refilled but nobody ever does?

It's so curious why these things are addictive. Before I tried a vape (it was called an e-cigarette back then) I thought the addictive thing about cigarettes is the nicotine. That's part of it, but a huge part (possibly even bigger) is just the sensation of sucking in smoke/vapour from a little stick and exhaling it. Is it similar to sucking on a mother's teat or something? It really seems to satisfy in a way nothing else does.

In the UK truly disposable vapes are banned, thankfully, but I do wonder if it's now just "technically refillable" ones that people use one time. They should be taxed to the eyeballs to encourage reuse if so.
