How Long Can You Store Weed? An In-Depth Guide

August 28, 2023

If you've ever found your ideal strain or stocked up during a sale, you may be wondering: how long can you store weed without it losing its mojo?

To help you become a savvy cannabis connoisseur, we'll go deep into the ins and outs of cannabis storage.

Let's dive right in.

Factors Affecting Cannabis Longevity

Humidity Levels

Marijuana craves a particular humidity level—too dry, and it gets brittle; too damp, and you risk mold. Aim for a 59% to 63% relative humidity level, which you can measure using a hygrometer.

Light Exposure

Keep your cannabis in the dark. UV rays degrade cannabinoids and terpenes. That beautiful glass jar on your window sill? Relocate it to a cupboard or drawer.


Keep your cannabis cool but not cold. Temperatures between 60-70°F (15-24°C) are generally considered ideal. Extreme temperatures can degrade the cannabinoids and terpenes, essential components in your cannabis.

Air Control

Believe it or not, the amount of air in your storage container matters. Too much air will dry out the cannabis, while too little can affect humidity levels.

The Shelf Life of Different Cannabis Products


High-quality flower can last up to two years if stored correctly. However, it's most potent within the first six months. After that, you may notice a gradual degradation in cannabinoid levels.


Edibles like cookies, brownies, or gummies generally have a much shorter shelf life. Be sure to check the expiration date on the packaging, or if you make them yourself, note the shelf life of the quickest-expiring ingredient.


Alcohol-based tinctures can last several years if stored correctly, away from light and heat. However, oil-based tinctures are better used within a year.


Think waxes, shatters, and oils. These can last up to a year, sometimes longer if stored under the right conditions.

Common Signs Your Weed Has Gone Bad


If your cannabis has lost its aroma or smells musty, it's probably expired.


Look out for any unusual spots or a moldy smell. It's not worth the risk of consuming moldy cannabis.


If your weed crumbles to dust in your fingers, it's time to say goodbye.

Color Change

If your vibrant green buds turn brown or yellow, they're past their prime.

The Art of Proper Storage

  1. Airtight Containers: Glass or ceramic containers are generally better than plastic, which can contain harmful chemicals.
  2. Temperature-Controlled Environment: A climate-controlled storage box can work wonders.
  3. Separate Strains: Different strains have distinct requirements for optimal storage. Keep them in separate jars.


What About Vacuum Sealing?

Vacuum sealing can extend your cannabis's shelf life by reducing its exposure to air.

Can I Use a Humidor?

Cigar humidors are not recommended because they are often made from cedarwood, which can affect your cannabis's flavor.

What About Pre-Rolls?

Pre-rolls degrade more quickly than whole buds, usually within a month, because they have more surface area exposed.

Can I Store Different Forms Together?

It’s best to store different forms of cannabis (flower, edibles, tinctures) separately to preserve their unique qualities.

Final Thoughts

Understanding how to properly store your cannabis can make all the difference in your experience. By being mindful of factors like humidity, temperature, and light, you can extend the life of your cannabis and enjoy it at its best for longer periods. While the answer to the question can weed go bad is a resounding Yes, there are plenty of solutions. Happy storing!
