How to Safely Store Cannabis Products in the uk
Storing cannabis products properly is essential to maintaining their potency, freshness, and safety. Whether you’re a recreational user or using cannabis for medical purposes, understanding the best practices for storage can enhance the overall experience and ensure you’re consuming cannabis in its optimal form. In this blog post, we’ll provide tips and guidelines on how to safely store cannabis products at home to keep them effective, fresh, and safe.
1. Keep Cannabis in an Airtight Container
Cannabis products, especially flower, can degrade over time if exposed to air. Oxygen can cause cannabis to lose its potency, flavor, and aroma. To preserve its quality, store cannabis in airtight containers, such as:
- Glass jars with airtight lids: These are excellent for preserving the freshness and potency of your cannabis. Glass is non-porous, so it won’t interact with the product inside.
- Vacuum-sealed bags: These are another great option, especially for long-term storage, as they eliminate air exposure.

Avoid storing cannabis in plastic bags or containers, as these can cause the product to dry out and degrade more quickly.
2. Store in a Cool, Dark Place
Cannabis is sensitive to heat and light, both of which can degrade cannabinoids (such as THC and CBD) and terpenes (which give cannabis its aroma and flavor). Exposure to sunlight and fluctuating temperatures can significantly reduce the effectiveness and quality of your cannabis products. To avoid this:
- Store your cannabis in a cool, dark place (ideally between 15-21°C or 59-70°F).
- Consider keeping your cannabis in a drawer, cabinet, or closet where it’s shielded from light and temperature fluctuations.
- If you live in a particularly hot climate, you might want to store cannabis in a temperature-controlled room or a refrigerator (but only if you have a suitable container).
3. Avoid Storing Cannabis in the Refrigerator (for Long-Term Use)
While it may seem like a good idea to refrigerate your cannabis, the cold, moisture, and fluctuation in temperature can negatively affect the quality of your cannabis. It can cause mold to grow or introduce excess moisture, which can lead to the development of mold or mildew. If you need to store cannabis in the fridge for short periods, make sure it’s in an airtight and moisture-proof container.
4. Monitor Humidity Levels
Cannabis is particularly sensitive to humidity levels. If the humidity is too high, the product can develop mold or mildew. On the other hand, if the humidity is too low, cannabis can dry out and lose its potency. To maintain an optimal balance, aim for a humidity level of around 55-62%. You can use a humidity pack (such as Boveda or Integra Boost) to regulate moisture levels and ensure your cannabis stays fresh.
- Humidity packs: These packs help maintain the perfect level of moisture, preventing your cannabis from drying out or becoming too moist.
5. Separate Different Cannabis Products
If you have multiple cannabis products, such as flower, edibles, concentrates, or tinctures, it’s essential to store them separately. Different types of cannabis products have unique storage requirements, so keeping them in their own containers will help preserve their individual qualities.
- Flower: Store in airtight containers as mentioned above.
- Concentrates and oils: These are best stored in glass containers or medical-grade silicone to avoid degradation.
- Edibles: Many cannabis-infused edibles (such as chocolates or gummies) should be stored in their original packaging or in airtight containers. Always store them in a cool, dry place to maintain their freshness.
6. Label Your Containers
If you have multiple cannabis strains or products at home, consider labeling your containers with the strain name, THC/CBD content, and purchase date. This way, you’ll have an easier time tracking the freshness and potency of your products, and you’ll know exactly what you’re consuming. Labeling is particularly helpful when storing edibles or concentrates.
7. Keep Cannabis Products Away from Children and Pets
As with any product, safety is key when storing cannabis at home. Children and pets should never have access to cannabis products. Always store your cannabis in a childproof container and keep it in a locked or secure location. Some tips to prevent accidental ingestion include:
- Use childproof containers for edibles or products with high THC content.
- Store cannabis in high, secure places out of reach from curious children or pets.
- Be mindful of edible cannabis products, as they often look like regular candy or food, which can be appealing to children.
8. Avoid Storing Cannabis with Strong Smells
Cannabis can absorb odors from its environment. If you store it near strong-smelling items like cleaning products, perfumes, or food, it may pick up undesirable scents. To prevent this, store cannabis in a sealed, odor-proof container to protect its natural aroma.
9. Storing Cannabis Concentrates and Vapes
For cannabis concentrates and vape cartridges, make sure to store them upright in their original packaging or in airtight containers to avoid leaking or contamination. These products are often more sensitive to heat and light, so be sure to store them in cool, dark places, away from any direct sunlight or temperature fluctuations.
- Concentrates: Store in glass jars or silicone containers to avoid degradation and preserve potency.
- Vape cartridges: Keep these in a cool, dry place and ensure they are upright to avoid leakage.
10. Long-Term Storage of Cannabis
If you’re storing cannabis for long periods, consider using more specialized storage solutions:
- Mylar bags with oxygen absorbers: These are great for long-term storage, especially if you want to ensure the cannabis stays in peak condition for several months.
- Vacuum-sealed containers: Vacuum sealing your cannabis removes air and moisture, which can keep the product fresh for an extended period.
