Cannabinol results from the degradation of THC. There is little of it in the fresh plant, but decarboxylation often raises the amount of CBN in the plant as an effect. CBN is only mildly psychoactive and has a higher affinity for the CB2 receptor than the CB1 receptor, linking CBN to the body’s immune system. In hemp oil, CBN is present in levels of 0.2% or lower.
Tetrahydrocannabinol is the most abundant cannabinoid in most medical and recreational marijuana strains. However, in hemp THC is a minor constituent and appears only in trace amounts under 0.3% by dry weight, as required by the U.S. government for hemp products. THC mimics the action of anandamide, a neurotransmitter naturally produced in the human body, and binds to CB1 receptors in the endocannabinoid system found mostly in the brain. The extremely low levels of THC in hemp make hemp oil non-psychoactive and safe for all ages to use.
The aforementioned entourage effect is the main reason behind the efficacy of whole plant extracts. There are over 100 ‘identified’ compounds in the cannabis plant. While most of these compounds have their own therapeutic benefit, they combine synergistically to provide a far better performance than any single compound, including CBD. Here are a couple of examples of conditions that benefit from the entourage effect:
