I will say, though, disposable vapes with microcontrollers inside (and even full games and screens from recent reporting) are an egregious source of e-waste. Many layers of stupid are present here.
My guy is out here pulling off the whole thing and tossing it in the trash.
Plus, many smoke alarms these days use a photoelectric sensor which don't wear out but are prone to false alarms from dust, etc. Smoke alarms SHOULD be cleaned at least once a year, by blasting them with compressed air. Dust buildup is a very common reason that smoke alarms stop working as well after any number of years. They require regular cleaning, just like everything else in the house.
Non-replaceable battery smoke alarms are popular because they are much more convenient to own. And you should NOT throw them away, the batteries in these contain lithium and must be recycled.
