Effective cannabis storage is imperative, whether for medical or recreational use, as it ensures the preservation of its quality, benefits and longevity.

Cannabis is most potent when it has been dried and cured. Cannabis loses its effectiveness with time, especially if it is exposed to heat and light.

There are a few techniques that have been used to maintain freshness. However, is freezing cannabis one of these?

First, The Basics

When you store cannabis, keep in mind that post-curing, cannabis thrives in cooler, dimly lit environments.

Exposure of the cannabis plant to temperatures exceeding 77 degrees Fahrenheit can facilitate the rapid development of mold and mildew.

On the other hand, if the temperature is too low, it can reduce the level of potency.

To get the best out of your cannabis, it is best to have it at a temperature between 50 and 60 degrees Fahrenheit.

Can You Freeze Cannabis?

Although you can freeze cannabis, it may not be the best cannabis storage solution.

A research project from the University of Mississippi on followed cannabis stored at room temperature (68º-72º F) for 4 years. Researchers found that over time THC loss was proportional to its time in storage. Surprisingly, the most THC loss occurred during the first year.

Here’s a breakdown of their findings:

  • 1 year in storage – 16.6% THC loss
  • 2 years in storage – 26.7% THC loss
  • 3 years in storage – 34.5% THC loss
  • 4 years in storage – 41.4% THC loss

The main argument in favor of freezing weed is that it’ll slow down the natural process of decarboxylation but the freezer may do more harm than good.

One of the main disadvantages of freezing cannabis is it’ll cause the trichomes to become brittle and likely fall off.

How to Freeze Cannabis

If you plan on freezing your buds, make sure you handle them with care to avoid breaking apart the trichomes. When you’re ready to use your buds, remove them from the freezer and give them some time to thaw.

The thawing process allows you to work better with the material without ruining the preserved trichomes, cannabinoids, and terpenes.

Also, consider the moisture content. Freezing can cause excess moisture to form ice crystals. Drying the weed appropriately can overcome this issue.

Vacuum sealing your weed can get rid of your moisture problems. Vacuum sealing your dried weed can keep it fresh (without ice formation) for several months.

However, vacuum sealing can overly compress your buds if you’re not careful. Some growers choose to use carbon dioxide or nitrogen to remove the excess air through the injection of the container. The excess air exits through a separate hole and the holes are sealed afterward.

Some growers choose to store weed in small containers (about a week’s worth) for personal use. When storing small quantities, choose small containers and store the rest in a separate larger container to leave it undisturbed.

Can You Freeze Cannabis Edibles?

Now, what about freezing other cannabis products apart from flower buds? Should you do it?

If you plan on making a big batch of edibles or cannabutter, refrigeration is critical. However, some edibles like gummies and candies can stay in an outside container without going bad.

Freezing your baked goods (brownies, cookies, etc.), cannabutter, or infused oil can keep them fresher for longer without losing too much potency. Freezing your edibles can extend their shelf life up to six months or more, in some cases.

Keeping them cool in the refrigerator before freezing can help the transition. When you’re ready to use them, take them out and allow them to thaw to room temperature.

Conclusion on Can You Freeze Cannabis?

Whether you bought or grew your weed, preserving its potency, aroma, and flavor is top of mind. The best cannabis storage practices for bud do not involve freezing it. Consider every aspect of the cannabis’ storage environment and look for a cool, airtight place with minimal light.
