You may notice expiry dates listed on some bottles of e-liquid, and – with food expiry dates being often inaccurate – it’s pretty natural to wonder whether expired e-liquid is really anything to worry about. The expiry date for e-liquid isn’t well-established, but following general guidance and trusting your senses helps you determine if a juice is safe to vape.
- There is no consensus on the shelf life of e-liquid, but based on the lifespan of nicotine, PG and VG it’s probably between one and two years. This may differ depending on which flavorings are present, though.
- If you leave e-liquid for a while, sediment may develop as the denser elements sink through the mix. This is normal, but if it doesn’t mix with the juice again when you shake it, this is a sign your juice may have gone bad.
- Otherwise, use the same criteria you would for food: if your juice smells or looks odd and you’ve had it for over a year, it’s probably gone bad
