Does Weed Lose Potency When It Dries? [View all]

Does Weed Lose Potency When It Dries?

While there’s no set expiration date, the potency of your weed can drop significantly after a few years.

It’s a slow fade influenced by several key factors:

Leaving your bud out in the open or in a plastic bag invites light and air to do their worst.

The cultivation process can majorly affect the potency of your cannabis. Excessive light bleaches potency, humidity can bring upon mold, and oxygen can slowly erode and degrade THC. Plants nurtured in conditions not optimized for the plant can make for weak THC levels.

Older studies highlight that weed’s THC content decreases over time:

First year: THC reduces around 16%
Second year: THC reduces around 26%
Third year: Around a 34% reduction in THC
Fourth year: THC potency reduces by around 41%.
