Anything that's broken, leaks, or has a battery that won't hold a charge should go. Continuing to use a damaged device isn't worth the risk. Check for:

• Cracks in the tank or mouthpiece
• Battery that drains fast or gets hot
• Leaks that happen regularly

If it's past its prime, recycle it properly. Many vape shops accept old devices. Don't throw lithium batteries in the trash—check local regulations for battery recycling.

Also retire devices that don't match your current nicotine strength or style. If you've moved to lower nicotine, that high-strength pod isn't doing you favors.
