There are times when you should break the rules. If your device has been through extreme heat—like sitting in a car for a week—treat it with extra caution. Heat can degrade the battery and cause leaks. If it feels hot or looks swollen, don't use it. Recycle it properly.

If you're traveling with your vape, the TSA has specific rules: e-cigarettes and vapes must be in carry-on bags, not checked luggage. That's non-negotiable for safety.

And if you're a sustainability-minded shopper, you might be tempted to stretch a device's life as long as possible. That's admirable, but there's a limit. A burnt coil won't un-burn. A dead battery won't revive. When a device stops working reliably, the sustainable choice is to recycle it at a designated e-waste or vape drop-off point—not to keep puffing on something that's past its prime.
