Ultimately, however, we are all different and it comes down to the individual user and their needs. If drug testing is a concern, you’re encouraged to seek out CBD isolate products (or terpsolates) instead of Full Spectrum.
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.
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:
