If you’re a vaping enthusiast in Canada, chances are you’re no stranger to the convenience and discreetness of a weed vape pen. These tiny wonders offer a quick and hassle-free way to enjoy your favourite THC cartridges.

But here’s the catch: THC vape carts have a shelf life like any other consumable product. To fully savour your vaping experience, mastering the expiration process is essential for the best possible outcomes.

After all, an expired vape cartridge won’t just leave you high and dry; it might leave you disappointed. In this article, we’ll unravel the mystery of THC cart expiration and arm you with the knowledge to detect when your oil cartridge has gone bad.

Yes, THC cartridges do have an expiration date. Over time, the potency of the THC and the quality of the vape cartridge components can degrade, affecting the overall experience. The expiration date depends on factors such as storage conditions and the freshness of the product. Using expired carts leads to a less effective high and potential health risks.

How Long Does a Weed Cart Last?

The lifespan of a weed cart largely depends on your inhalation style. If you take one-second puffs, a 500 mg cartridge lasts around 150 puffs. That’s about 50 days with three puffs daily. For longer pulls, like 3 or 6 seconds, the vape cartridge won’t last as long.

A 3-second drag would also go for 50 days, but three daily pulls deplete it in three to four weeks. For those taking 6-second drags, the duration reduces by half.
