All cannabis (including marijuana and hemp) is now considered botanically to be Cannabis sativa. Differences between strains are largely due to different combinations of cannabinoids and terpenes (and possibly other substances).
Dr. Ethan Russo believes that some challenging syndromes, such as migraine headaches and fibromyalgia, are actually due to an endocannabinoid deficiency. In China migraines and fibromyalgia might be addressed as imbalances in Qi (pronounced “chi”). Qi is the concept of vital energy. Is the endocannabinoid system the same as Qi? Do they at least overlap?
At the same time that the U.S. government maintained that cannabis was an illegal drug with no medical value the U.S. Department of Health and Human services took out a patent on “Cannabinoids as antioxidants and neuroprotectants.” This apparent hypocrisy is the result of scientists and politicians having very different agendas.
Spike Jonze has produced a two minute history of cannabis for MedMen. It puts things into perspective.
I ordered an ounce of “Heavy Lifter” CBD flower from Starseed Botanicals a few weeks ago and they were out. Instead of letting me know this, they “upgraded” me to their Lifter Private Reserve (PR). When I looked over the lab tests I saw that Lifter PR had 11% CBD – a little over half of the CBD content of the Heavy Lifter
A 2019 study has found that CBD’s effect may not be restricted to it’s effect on the endocannabinoid system. CBD also acts on receptors that bind the neurotransmitter serotonin (5-HT1A) that is involved in anxiety and on receptors that bind vanilloid (TRPV1) that is involved in pain.
Law enforcement has field tests for marijuana that can’t distinguish CBD hemp flower from marijuana. If you live in a place where marijuana is illegal and CBD flower is legal you should take care with your hemp flower.
THCA is a non-intoxicating cannabinoid found in high levels in the marijuana form of the cannabis plant. Smaller quantities are often also found in the hemp form of cannabis. In the U.S. hemp is defined as any cannabis containing over 0.3% delta-9 THC. The THCA content doesn’t count (according to most interpretations of the 2018 Farm Bill). In the E.U. hemp must have 0.2% delta 9 THC or less.
