Let's delve into the intriguing world of weed potency and its expiration to dispel any doubts and enhance your cannabis enjoyment.




How Does Cannabis Age?


As cannabis ages, its potency can change over time, impacting its overall quality and effects. Understanding how cannabis ages and the factors that influence its potency is essential for both recreational and medicinal users.

During the flowering cycle of the cannabis plant, a cannabinoid acid known as cannabigerolic acid (CBGA) is produced. CBGA is an important compound that is used to create other major cannabinoids such as cannabidiolic acid (CBDA), tetrahydrocannabinolic acid (THCA), and cannabichromenic acid (CBCA). Decarboxylation, or heating, converts inactive compounds in trichomes into primary cannabinoids like THC, CBD, and CBG.

Several factors affect the aging process of cannabis, including exposure to light, air, heat, and humidity. Over time, cannabinoids like THC and CBD can degrade, leading to a decrease in potency. This degradation process can result in a milder high and reduced therapeutic benefits.

When you purchase cannabis buds from a licensed retailer, you will receive nugs that contain some primary cannabinoids but mostly inactive cannabinoid acids. Heat, light, and moisture cause chemical reactions in cannabinoids and terpenes. If cannabis buds were left in a mason jar indefinitely, the THCA would convert to THC and eventually degrade into cannabinol (CBN) due to light and high temperatures.

The United Nations Office on Drugs and Crime published a study that measured the THC concentration of buds stored at room temperature for four years.

Proper storage is crucial to preserving the potency of cannabis. Storing weed in a cool, dark, and airtight container can slow down the degradation process. Additionally, keeping the humidity levels controlled helps prevent mold growth and maintain the quality of the buds.

It's important to note that some strains may age differently than others. Sativa strains, for example, may be more susceptible to potency loss compared to indica strains.

Cannabis plant material lost THC concentration at the following rates on average:

  • THC loss of 16% after one year
  • THC loss of 26% after two years
  • THC loss of 34% after three years
  • THC loss of 41% after four years


Does Weed Go Bad, Stale or Expire?


When it comes to weed potency, many people wonder if cannabis can go bad, stale, or expire over time. The answer is yes, weed can indeed degrade and lose its potency over time if not stored properly.
