And now, onto the thorny issue of legality. The simple answer to the question is yes – if it is extracted from hemp. The 2014 Farm Bill established guidelines for growing hemp in the U.S. legally. This so-called “industrial hemp” refers to both hemp and hemp products which come from cannabis plants with less than 0.3 percent THC and are grown by a state-licensed farmer.
“When purchasing a CBD product, keep in mind that a transparent company’s CBD milligram (mg) strength is reflective of the actual active CBD in that particular product,” states Farias. “If a bottle says 250 mg of CBD, then that product should contain 250 mg of actual active CBD. However, a lot of companies currently in the market will list the mg dosage of their CBD hemp oil without publishing the strength of their actual active CBD.”
Cannabidiol (CBD) is one of dozens of non-psychoactive cannabinoids found in the hemp plant. Cannabidiol, and all the other cannabinoids, were patented by the United States Government in 2003 as neuroprotectants and antioxidants (Patent No. 6,630,507). Cannabinoids are characterized by their ability to act on the cannabinoid receptors that are found throughout the body. CBD and other cannabinoids are naturally occurring compounds that display potent anti-inflammatory and pain-relieving properties. They can promote the body’s healthy regulation of the central nervous, immune, and endocannabinoid systems.
In order to account for the low CBD content of these hemp plants, manufacturers have to process large volumes of raw material at a time, with the idea of extracting just enough CBD so that they can label their product as a “CBD oil.” While this method is fine in theory, what ultimately ends up happening (unless the manufacturer’s extraction methods are state of the art), is that traces of chemicals cane end up being left over in the final product. These chemicals can potentially contain harsh solvents such as butane, hexane, and propylene glycol, which has been known to break down into carcinogenic (cancer-causing) compounds like formaldehyde and acetaldehyde.
In fact, numerous studies have looked at the relationship between CBD and pain, and the results are promising. Researchers have looked at various kinds of pain – from joint pain to cancer pain. One finding is that CBD increases levels of glutamate and serotonin – both neurotransmitters that play a role in pain regulation. And CBD’s anti-inflammatory properties help by tackling the root cause of much chronic pain.
