Can stored cannabis be smoked? Tips for consuming old cannabis

Although storing cannabis is a peculiar topic, there are situations where after a while, we find ourselves with old buds that we have forgotten or lost. It is therefore natural to wonder whether it is safe to consume old cannabis or whether it is safe to do so.

Today we will look at what happens to cannabis after years of storage and whether it is possible to smoke old buds.

Why long term cannabis storage?

It is important to understand why someone would want to store cannabis long term.

There are several reasons why someone might want to do so. For example, a grower might want to store a harvest to keep it fresh until it is time to sell it. Or perhaps a consumer might want to keep a supply of cannabis for personal use or to share with friends.

In either case, it is critical to know how to store it properly to prolong its shelf life and maintain its potency, flavor and aroma.

How long can cannabis last in storage?

When stored properly, cannabis can last for quite some time without losing its potency. Its freshness depends on several factors, such as the quality of the crop, the curing method and the level of humidity in the environment.

In general, fresh cannabis is believed to last about six months to a year. However, if stored properly, cannabis can last for years without losing its potency.

What happens to marijuana after years of storage?

Taking a five-year-old cannabis sample as an example and sending it to an analytical laboratory for testing. This sample was stored in a glass jar to minimize exposure to oxygen, the results obtained were:

The color of the buds diminished and lost its luster, the amount of THC still remaining in the cannabis was high, indicating that there had been very little degradation of THC to CBN. THC transforms to CBN when exposed to oxygen, this means that the limited exposure to oxygen had helped maintain the potency of the cannabis.

Is it safe to consume old cannabis?

Although old cannabis may not be as potent as fresh cannabis, it can still be consumed without problems. In fact, some users prefer older cannabis because it has a more relaxing and sedative effect.

When THC is degraded into CBN, cannabis produces a more sedative effect, making it ideal for use before bedtime.

How to properly store cannabis to prolong its shelf life?

To properly store cannabis and prolong its shelf life, it is important to follow a few key steps:

  1. keep cannabis in a cool, dark place to avoid trichome degradation. Trichomes are the source of the cannabinoids and terpenes that give cannabis its aroma, flavor and effects.
  2. Exposure to light and heat causes the trichomes to decompose, which affects the quality of the cannabis.
  3. It is also essential to keep cannabis in a place with adequate humidity. Too much humidity can cause cannabis to mold, while too little humidity can cause buds to dry out and become brittle.
  4. Store cannabis in an airtight container to minimize exposure to oxygen and keep the potency of the cannabis intact.

How do you know if your cannabis is bad?

There are many signs to identify when cannabis is bad. For example, if the cannabis has a musty or moldy smell, it is likely that it has been exposed to too much moisture and has molded.

If the buds crumble easily or feel dry and brittle, it is likely they have lost their moisture and potency.


Storing cannabis for a long time is possible if the proper steps are followed to maintain its freshness and potency. Although old cannabis may not be as potent as fresh cannabis, it can still be consumed without problems.

By following the right tips for storing cannabis, it is possible to extend its shelf life and ensure that you always have a good supply to smoke.
