Does Weed Expire?

If you've ever stocked up on bud and didn’t get around to smoking it all, you may be wondering how long you can keep it. Like any other plant-based substance, cannabis can expire over time. 

This blog will explore the shelf life of cannabis and how to tell if it has gone bad.

Does Cannabis Expire?

Yes, cannabis can expire. The shelf life of cannabis depends on several factors, including its form, storage conditions, and quality. The primary culprits that contribute to the deterioration of cannabis are exposure to light, heat, moisture, and oxygen. 

Over time, these environmental factors cause a chemical breakdown of the cannabinoids, terpenes, and flavonoids that make up the plant, resulting in a loss of potency and flavour.

Cannabis Flower Shelf Life

The shelf life of cannabis flower depends on how it is stored. Proper storage can extend its lifespan, while poor storage conditions can reduce its shelf life significantly. Generally, cannabis flower stored in an airtight container, in a cool, dry place, away from direct sunlight can last up to six months or more.

However, cannabis flower exposed to light, heat, and moisture can lose its potency and develop mould and mildew, making it unsuitable for consumption. Signs that cannabis flower has gone bad include a stale odour, a musty or mouldy smell, or a change in colour from green to brown.

Cannabis Edibles Shelf Life

Cannabis edibles, such as brownies, gummies, and chocolates, have a longer shelf life than cannabis flower. However, their shelf life depends on the type of food they are infused with and how they are stored. Generally, cannabis-infused edibles that are stored in an airtight container in a cool, dry place can last up to six months or more.

However, it's essential to note that the shelf life of cannabis edibles is not the same as the expiration date on the packaging. The expiration date on the package is for the food item itself, not the cannabis infusion. Over time, the potency of cannabis edibles can decrease, and they can develop a stale odour or a rancid taste.

Cannabis Concentrates and Tinctures Shelf Life

Cannabis concentrates and tinctures have a long shelf life and can last up to a year or more if stored correctly. Proper storage involves keeping them in a cool, dark place, away from heat and light. Exposure to heat and light can cause them to lose potency and develop a bitter taste.

Signs that Cannabis Has Expired

If you're unsure whether your cannabis has expired, here are some signs to look out for:

Stale or musty odour: Fresh cannabis has a pungent and earthy smell. If your cannabis has a stale or musty odour, it may be a sign that it has gone bad.

Mould or mildew: Mold and mildew can grow on cannabis that has been exposed to moisture. If you notice any mould or mildew on your cannabis, it's best to discard it.

Change in colour: Fresh cannabis is green, but as it ages, it can turn brown. If your cannabis has changed colour, it may be a sign that it has lost its potency.

Takeaways 

In conclusion, cannabis can expire, but the shelf life depends on several factors, including its form, storage conditions, and quality. Proper storage can extend its lifespan, while poor storage conditions can reduce its shelf life significantly. To ensure that your cannabis lasts as long as possible, store it in an airtight container in a cool, dry place, away from direct sunlight, heat, and moisture.
