The UNODC describes Cannabinol (CBN) on page 27 in their publication “Recommended Methods for the Identification and Analysis of Cannabis …” as non existent in fresh and carefully dried cannabis. If this cannabinoid is present in a given sample of cannabis, the UNODC states that the sample is degrading.
CBN is a degraded form of THC – as it does not occur naturally but is an artifact.
Evidence shows that THC appears to degrade at a higher rate in the first year after harvest, relative to subsequent years.
Since the recreational cannabis market is set to commence in 2017, cannabis inventory at the approved licensed producers in Canada far outweigh demand.
What is very disturbing about the Marijuana for Medical Purpose Regulations (MMPR) is that LP’s are only required to disclose the percentage of THC and CBD. Since they are stockpiling their product, licensed producers should be required to disclose CBN.
