The basics
Cannabinol is a distinct cannabinoid with the formula C21H26O2. Storage research tracks changes in cannabinoids, including CBN, under specific conditions.
What the evidence means
A measured CBN level is a chemical result. It is not, by itself, a sleep score. A storage experiment does not establish that an older retail product will be more sedating for a person.
A useful question
Is CBN actually measured in the batch, and what human evidence supports any sleep claim?
Sources and further reading
Use the sources to check the scope of each claim. A chemical measurement, a laboratory experiment and a study in people answer different questions.
