Can You Freeze Weed?

We freeze our food to extend its shelf life; can we do the same with cannabis?

So you’ve found yourself with too much bud (as if that’s possible) and want to keep it fresh for as long as you can.

You’ve probably heard that too much humidity could lead to mold and mildew, destroying your buds and their cannabinoids.

In order to combat high humidity, throwing your bud in the freezer seems like a reasonable and logical step to take! I mean, it works for food, right?

Unfortunately, the simple answer to whether or not you should freeze your weed is a resounding no. Read on to learn more about why you should keep your weed out of the freezer.

Why Shouldn't You Freeze Weed?


After working long and hard to grow and harvest your weed, improper storage can quickly become a nightmare.

Similar to the dangers of heat and humidity, cold temperatures also have their own negative effects on cannabis. One of the main damages from freezing weed is how it affects decarboxylation.

What the hell does that mean, you might ask? Simply put, decarboxylation is a chemical process that occurs within cannabis when we administer heat.

Raw cannabis contains a lot of THC-A, which is non-psychoactive, and through the process of decarboxylation, it turns into THC, the chemical compound that gets you high.

When we introduce heat to our buds, usually brought on by a lighter spark or an oven, it will transform THC-A into psychoactive THC.

Here’s a visual.

Non-psychoactive THC-A -> Decarboxylation -> Psychoactive THC

Storing your cannabis at temperatures that are too low (like in the freezer) can seriously hinder the weed’s ability to decarboxylate properly, thus leading to a less potent product.


Another equally important reason why you shouldn’t freeze your weed is it affects your precious trichomes.

You may have noticed the fine white hair-like particles that cover your bud. These resin glands are known as trichomes. If you just harvested some buds, you’ve probably watched them closely as they developed from clear to milky or amber-colored.

These glands are not only responsible for giving each strain its unique taste and smell, but they are also where cannabinoids like THC and CBD are most prevalent. Trichomes play an essential role in terms of how high you can get.

Freezing your weed literally causes these trichomes to crystallize like small ice particles, and your subsequent handling of the bud will cause them to break off like mini twigs.

Most storage containers/bags will also be affected by static charge, so even if your handling is kept to a minimum, the container will do the damage for you.

After all the care taken with your bud up to this point, losing your trichomes can be devastating. This can affect;

  • The taste of the smoke
  • The smoothness/harshness of the smoke
  • The buds’ level of psychoactivity

How Should I Store My Weed?

There are some simple steps to follow which can lead to a longer-lasting, fuller-flavored, and better-smoking bud:

  • Store In A Cool, Dark Place: Whilst controlling humidity will help prevent mold and mildew on your bud, overexposure to UV rays has proven to be the greatest factor in the breakdown of cannabinoids.
  • Glass Storage Containers/Jars: Glass not only possesses a neutral charge, but you can also ensure an airtight seal for your product.
  • Vacuum Seal & Dehumidify: If you’re looking to store long-term, you’ll want to ensure the right amount of oxygen is stored with your bud. This can allow your bud to finish curing in storage without adversely affecting humidity levels, keeping your product fresher for longer.

We have put out a wealth of information about better storage techniques, so I won’t go into too much detail.
