Most things we consume has an expiration date that guides us on whether something has spoiled or not. Some have wondered if marijuana can go bad, since it is now a product that we use from more than just smoking. From beverages to oils to all sorts of edibles, cannabis offers a wide range of consumption options. But can weed go bad and how do we know that it has?

Dangers in Old Weed

The short answer is, weed doesn’t go bad…exactly. While cannabis can get stale and be a little off, it is unlikely to cause any harm if you ingest a batch that is not fresh. The worst thing that might happen is that the potency drops off for you, which may be an issue if you’re taking it for medicinal value. There may also be a change in taste and texture when dealing with stale cannabis. Have you seen our collection of Canadian weed pipes?

However, weed can be affected by mold too, which is difficult to detect. Look for white powdery or fuzzy spots on your batch and see if it smells musty. Moldy weed may not cause any permanent harm under normal circumstances but can cause nausea, vomiting, coughing. For those with immunodeficiencies can suffer greatly from even being around smoke from weed that has been infected by mold, the effects of which could lead to death, so it is important to examine old weed carefully. If it doesn’t seem right, it’s not worth the risk.

How Long Does Weed Stay Fresh?

How you store your weed will determine how long it stays fresh. Keep in mind that light, temperature, humidity, and oxygen can all affect freshness and therefore potency, flavour, and aroma. The best way to store cannabis is in a tightly sealed glass jar, so no plastic containers or baggies, and no tins. Keep it in a cool, dark, and dry place with a relative humidity of around 60% at temperatures below 25-degrees Celsius.

When stored properly, your dried cannabis should stay fresh for up to 1 year. Beyond that, and it begins to lose its potency, but you can still benefit from it even years later.

How Can I Tell if My Weed is Spoiled?

Your biggest clue would be in the smell. If your cannabis smells different than it used to, or not at all, you know it’s old. Alternatively, some varieties may smell stronger and taste harsh.

Old weed may also look different, appearing either more brittle or spongy, indicating it has become too dry or too moist.

As long as there is no mold present, consuming your old weed should not prove harmful at all. The main thing is to avoid mold. The dangers that mold can create for you and for those around you can turn a pleasant experience into a deadly one. So for the most part, you don’t have to worry too much about whether weed has gone bad or not, just look for the signs.
