Good question and completely subjective. No two people will answer this the same. If you don’t store pot properly, the terpenes (smell) and buzz degrade, but never really go away. However, it’s said that cannabis plants have a one-year shelf life.
Canopy Growth explained that the THC, a cannabinoid that provides some of the health benefits of marijuana as well as the “buzz,” can degrade over time if the flower is not stored properly.
“Cannabis is best stored in an air-tight container and left in the dark, because light degrades the THC, so it’s generally best to store it in the dark,” Greenblatt said.
Walsh said that even with proper storage of the dried cannabis, the chemicals in the flower, called cannabinoids, break down and change over time.
