THC (tetrahydrocannabinol), the primary psychoactive compound in cannabis, can degrade or evaporate over time, but this process depends on several factors such as storage conditions, exposure to light, temperature, and air. Proper storage is critical to preserving THC potency. Over time, THC can degrade into other compounds like CBN (cannabinol), which has different effects. While evaporation is not the primary mechanism of THC loss, improper storage can lead to significant degradation.

Key Points Explained:

1. THC Degradation vs. Evaporation

   • THC does not evaporate in the same way as water or alcohol. Instead, it primarily degrades due to environmental factors.
   • Degradation occurs when THC is exposed to heat, light, or oxygen, converting it into other cannabinoids like CBN, which is less psychoactive.
   • Evaporation is minimal unless THC is in a liquid form (e.g., in vape cartridges or oils) and exposed to high temperatures.

2. Factors Affecting THC Degradation

   • Temperature: High temperatures accelerate THC degradation. Storing cannabis in a cool, stable environment is essential.
   • Light: UV light breaks down THC molecules. Opaque, airtight containers can mitigate this.
   • Oxygen: Exposure to air oxidizes THC, reducing its potency. Vacuum-sealed containers are ideal for long-term storage.
   • Humidity: Excess moisture can lead to mold, while too little can dry out the plant material, making THC more susceptible to degradation.

3. Storage Recommendations to Preserve THC

   • Use airtight, opaque containers to minimize exposure to air and light.
   • Store in a cool, dark place, ideally between 60-70°F (15-21°C).
   • Avoid frequent opening of the container to reduce oxygen exposure.
   • For long-term storage, consider vacuum-sealing or using humidity control packs.

4. THC Degradation Over Time

   • Studies show that THC levels can decrease by 10-20% within a year, even under optimal storage conditions.
   • After two years, significant degradation may occur, with THC converting into CBN or other cannabinoids.
   • The rate of degradation depends on the form of cannabis (flower, oil, edibles) and storage practices.

5. Practical Implications for Consumers

   • For those purchasing cannabis products, check expiration dates and storage recommendations on packaging.
   • Avoid purchasing products that have been stored improperly (e.g., in direct sunlight or high temperatures).
   • For long-term storage, consider freezing cannabis in airtight containers, though this may affect texture and flavor.

By understanding these factors, consumers can make informed decisions about purchasing and storing cannabis products to ensure maximum potency and quality.

Summary Table:

Factor	Impact on THC	Storage Solution
Temperature	High temperatures accelerate THC degradation.	Store in a cool, stable environment (60-70°F / 15-21°C).
Light	UV light breaks down THC molecules.	Use opaque, airtight containers.
Oxygen	Exposure to air oxidizes THC, reducing potency.	Vacuum-seal containers or limit oxygen exposure.
Humidity	Excess moisture causes mold; too little dries out plant material.	Use humidity control packs for balanced moisture levels.
Time	THC levels decrease by 10-20% annually, even with proper storage.	For long-term storage, vacuum-seal and freeze in airtight containers.
