How Long Does Weed Potency Last?

If you have ever come across a long-forgotten weed container stored in a closet or basement, you will notice that the potency had decreased significantly from when it was first obtained. This is due to a phenomenon known as “cannabinoid degradation.” As marijuana ages, its potency decreases because oxidation breaks down tetrahydrocannabinol (THC), the chemical compound that produces the psychoactive effects in cannabis.

With the legalization and mainstreaming of cannabis, many consumers find themselves with a lot more products than they need. These people are likely to let their weed go to waste as they do not know how to store marijuana. Knowing how to store your marijuana can make a big difference to the potency of your weed in the long run.

So, How Long Does Weed Potency Last?

There is no definite timeframe for how long weed potency lasts. Every cannabis strain and product reacts differently to the aging process. Once you open the flower in your grinder, you can still expect its potency to last for eight weeks. However, after this period, it will no longer be as potent as the day it was first opened and will begin to lose its potency even much sooner than that. There are several reasons for this, so let’s discuss them.


Humidity plays a significant role in the longevity of your weed. If you have an airtight jar dispensary, you can expect the pot to be much more potent than if it’s exposed to high humidity levels. Humidity will cause your herb to dry out and lose a lot of its flavor, especially if it was dried before sealing. A plastic bag is enough protection against climate damage but not humidity. A vacuum-sealed glass container should be used if you want to protect your stash.


Exposure to light will cause your bud to deteriorate because light degrades the THC. Do you know that green plant smell that comes from your weed? That is the smell of the terpenes in weed reacting with oxygen. In a vacuum-sealed container, the terpenes are preserved, but they won’t react with oxygen, so they will lose their unique smell and begin to fade within a week or two. Therefore, a dark glass container is essential for keeping your herb potent for as long as possible.


Temperature also has a significant impact on the potency of your herb. Even if it is under the same temperature as a room full of other containers, if it is exposed to heat or extremely hot or cold temperatures, you can expect it to lose much more potency than if you stick with average room temperature.

Does Weed Go Bad?

It doesn’t go bad, but it will lose its potency and flavor. The best way to keep your pot as potent as possible is to invest in a storage container to control light, humidity, heat, and cold. Even in a vacuum-sealed container, you can expect your weed to last six months. It is recommended that you keep your herb in a cool, dark place.

Does Weed Get Old?

How Long Does Weed Potency Last

Yes, it does! Weed gets old and loses its potency over time. The cannabinoids will break down as they react with oxygen, and your cannabis will lose some of its taste. This is why it should be stored in an airtight container to keep out air, which will slow the rate at which it breaks down. It is best to store your cannabis in a cool, dark place out of sunlight, but even sealed containers will degrade.

How Long Does Weed Stay Good?

It depends on the material you use for storage. If you store your pot in a Ziploc bag, your weed will quickly absorb moisture from the air and become rather unusable. In general, weed can stay fresh for about a year, but you should still expect your bud to lose its potency after several months. If you intend to store your marijuana longer than this or want to be prepared for a rainy day, then vacuum-sealed containers are the best way to ensure that they will last as long as possible.

How To Choose Your Weed Container

The most important feature of a weed container is that it is airtight. If you store your marijuana in a container that allows air to permeate, you will quickly find yourself with stale weed. A vacuum-sealed container is the best way to preserve the freshness of your herb, but even these containers cannot preserve your marijuana indefinitely. When buying or choosing a container, you should search for those made from glass, stainless steel, ceramic or high-grade plastic. They will allow for the most significant retention of potency inside your marijuana.

Does Weed Expire?

In general, no. Weed doesn’t expire, but it does lose its potency over time. Some cannabinoids will break down and degrade over time, so your weed won’t last forever, but it can certainly last a while if you store it in the right conditions. For example, weed’s THC content will degrade if exposed to light or stored at high or low temperatures. On the other hand, if you keep cannabis storage in a cool dark place and use a vacuum-sealed container to store it in, your weed will last much longer.
