Cool, dark and dry. Control temperature, humidity and light, and you extend the fourth variable: time.

Why storage conditions matter
- Improper storage produces an off smell and an amber color. Both are signs the product has lost psychoactive potency, with much of the THC broken down into CBN.
- Degraded concentrate is not toxic on its own. Concentrate is considered unsafe when mold, bacteria or toxic chemicals such as pesticides are present.
- Rodent studies suggest CBN may have neuroprotective and antibacterial properties and act as an appetite stimulant.
The four environmental conditions
| Condition | Target |
|---|---|
| Temperature | Below 70°F (21°C) |
| Humidity | 59 to 63 percent |
| Light | Dark, sealed container. No UV exposure, no moisture getting in |
| Time | The variable you extend by controlling the other three |
What degradation looks like
As psychoactive cannabinoids degrade into non-intoxicating ones, concentrate turns amber and its smell changes, in extreme cases to something off-putting, like ammonia. Fresh concentrate is light in color. Concentrate degraded by UV and heat is visibly darker.
Dark, airtight container. Below 70°F (21°C). 59 to 63 percent humidity.
- Do not consume product that shows mold or bacterial growth.
- The same principles hold for storing CBD-A and CBD.
- Follow all testing and storage rules that apply in your jurisdiction.
