Sometimes we run across an article on another website that’s simply too good not to share.
PBS has an article that we’d love for you to read. You can access the entire article here.
Don’t have the time to read the whole thing? We got you. Here’s a few highlights from the article.
On the history of cannabis…
Cannabis, which has been cultivated by humans for at least 12,000 years, is “one of the oldest plants on record as having been used for human benefit,” said Shelley Durocher, a UConn research grower who manages the hemp greenhouse for the class. It’s a fascinating plant that occupies a unique space in the natural world, Durocher said, one that has helped shape the modern existence of Western countries like the U.S.
As hemp, its fiber made the sails that carried European colonists across much of the known world. It was so fundamental to America’s foundations that its image was printed on money. George Washington was notoriously bad at growing hemp, though.
On “What is cannabis?”…
Cannabis has many names, strains and varieties, including hemp and marijuana. But these days, they’re all considered one species: Cannabis sativa.
“Marijuana” is any cannabis plant with abundant amounts — technically, more than 0.3 percent — of the mind-altering drug THC. ….“Hemp,” by contrast, cannot legally contain more than 0.3 percent THC.
On hemp “accidentally” becoming marijuana…
Thanks to the “miracle” of reproduction, a hemp crop can start off making only CBD and then unwittingly turn into a THC-laden field of marijuana.
Let’s just say that again because it is a bit mind-blowing. A hemp crop — that is federally legal and only makes CBD — can become marijunana. Studies have found that if two certifiable hemp plants hook up, most of their offspring will be able to make THC. In fact, some of these seedlings will ONLY make THC.
On the importance of proper CBD extraction…
To collect CBD or THC from hemp, farmers harvest the plants and send them to an extractor, who collects the drugs and preps them for sale. The issue is that extracting CBD or THC is essentially the same process. If your supplier does it incorrectly, your CBD bottle might carry an illegal dose of THC.
On how CBD works within the body…
Akin to dopamine and serotonin, endocannabinoids can operate like neurotransmitters — the chemical messengers that activate or switch off our nerves. That, in turn, sparks or dampens the electric pulses that create our thoughts, behaviors and movements.
Our nerves receive those chemical messages through neurotransmitter receptors — think of them like radio antennas. Cannabinoids have two known receptors called CB1 and CB2.
This is where the mental effects of THC and CBD differ. THC makes us high because it has a strong affinity for the CB1 receptor, but CBD is the opposite. CBD does not typically interact with the CB1 receptor…at least not directly. Research shows CBD can elevate the body’s self-made endocannabinoids, and scientists are also hunting for a “hidden” brain receptor for the cannabis extract.
On the legality of CBD…
Yes, purchasing CBD is federally legal as long as it doesn’t contain more than 0.3 percent THC, but some state laws have put restrictions on buyers. For example, Virginians can only buy and possess CBD if they have a prescription.
