Don't carry a disposable vape in your back pocket and sit on it. The pressure can crack the casing or force juice into the mouthpiece. Same goes for tight jeans pockets—bending over can stress the device.

Don't carry it loose in a purse with sharp objects. Keys, coins, and nail files can scratch the finish or damage the mouthpiece.

And don't, under any circumstances, try to disassemble a disposable to change the coil or refill it. That's a fire hazard and a mess waiting to happen. If you're interested in a refillable option, look at pod systems instead.

Finally, avoid carrying multiple disposables in the same pocket. They can rub against each other and cause leaks. If you're testing several flavors, keep them in separate compartments or a small organizer.
