Vape pens contain lithium batteries, which shouldn't go in the regular trash. They can cause fires in landfills. Look for local e-waste recycling programs. Many electronics stores have drop-off bins. Some municipalities have scheduled pickups for hazardous waste. Check the EPA's guidelines for battery disposal. It's a small step, but it keeps harmful materials out of the environment.

If you're buying a new pen, consider the brand's sustainability practices. Some manufacturers offer take-back programs. But even if they don't, you can recycle the battery separately if you're handy. Just remove the battery if possible and recycle it. The rest can often go in the trash, but check local rules.
