Do THC vape pens have an expiration date?

Yes. Weed pens and cartridges have expiry dates, typically printed as an “exp” or “best before” on the box or batch label.

Over time, flavourings can fade, carrier liquids may thicken, and cannabinoids gradually degrade, especially if exposed to heat, light, or air. Using products before the stated date helps maintain consistent taste, vapour production, and reliability.

Store upright, capped, and away from sunlight to extend shelf life. If a cartridge tastes burnt, looks discoloured, or feels unusually thick, it may be past its best even if unopened.
