Yes, vapes and e-liquids can expire, although they don’t have a strict expiration date like food products. Here are some key points to consider:

1. E-Liquid Shelf Life
Typical Duration: Most e-liquids have a shelf life of about 1 to 2 years when stored properly.
Signs of Expiration: Look for changes in color, texture, or smell, which may indicate that the e-liquid has degraded.
2. Nicotine Stability
Nicotine Degradation: Over time, nicotine can break down, affecting the potency and flavor of the e-liquid.
3. Vape Devices
Battery Life: The battery in a vape device can degrade over time, especially if not used regularly or if stored improperly.
Coils and Tanks: These can also wear out and should be replaced regularly for optimal performance.
4. Storage Conditions
Cool and Dark Place: Store e-liquids in a cool, dark place to extend their shelf life and maintain quality.
Conclusion
While vapes and e-liquids don't have a specific expiration date, they can degrade over time. It's best to check for any noticeable changes and store them properly to ensure quality.
