Several weeks after a hysterectomy last spring, Bo Roth was suffering from exhaustion and pain that kept her on the couch much of the day. The 58-year-old Seattle speech coach didn’t want to take opioid pain-killers, but Tylenol wasn’t helping enough. Roth was intrigued when women in her online chat group enthused about a cannabis-derived oil called cannabidiol (CBD) that they said relieved pain without making them high. So Roth, who hadn’t smoked weed since college but lived in a state where cannabis was legal, walked into a dispensary and bought a CBD tincture.
The furry subjects, 277 Wistar rats, were given a dose of CBD immediately after receiving a small electric shock. The CBD-treated subjects were found to spend less time frozen in fear when reintroduced to the context of the fearful event. This means the CBD disrupted consolidation (or more simply put: memory strengthening) of their specific and long-term fear memory.
Hemp oil does have a number of uses and is often marketed as a cooking oil or a product that is good for moisturizing the skin. It is also used in the production of certain soaps, shampoos, and foods. It is also a basic ingredient for bio-fuel and even a more sustainable form of plastic. Hemp has been cultivated and used for roughly 10,000 years, and it definitely has useful purposes. However, a lack of cannabinoids, namely CBD, means that it has little therapeutic value.
