While most people assume CBD doesn’t contain THC, there are still trace amounts found in CBD oil that is made using the entire hemp plant. This is known as full-spectrum CBD and can be sold legally as long as it contains less than 0.3% THC. While this minuscule amount typically isn’t enough for people to feel any psychoactive effects, it can still show up in a person’s system.
Basically, cannabis is an umbrella term that includes both hemp and marijuana plants. Cannabis sativa is actually the scientific name of the cannabis plant (Cannabis = genus; sativa = species), and hemp and marijuana are just two different “varieties” of it (i.e. you could refer to both marijuana and hemp plants as “cannabis” plants, but you would not, for instance, refer to a “marijuana” plant as a “hemp” plant). Hopefully that’s not too confusing.
The reason so many people are interested in cannabis products that don’t make them high, proponents say, is that CBD helps with everything from pain and nausea to rheumatoid arthritis, cancer, Crohn’s disease, and dementia. CBD is anti-inflammatory, anti-anxiety, antibacterial, immunosuppressive, and more, says Joseph Cohen, D.O., a cannabis doctor in Boulder, CO.
The first step to finding your correct CBD dosage is getting as much information as you can about the product you’re using. What is the concentration of CBD? Are there third-party lab tests that can confirm that? The CBD industry is still mainly a grassroots therapeutic movement, and as such, largely unregulated. Concentration and purity levels can differ greatly depending on the manufacturing process.
That's not to say CBD-infused creams definitely won't reduce your acute pain or muscle soreness. That's because pretty much all of these creams on the market right now have other scientifically-proven analgesic compounds, like menthol, camphor, and capsaicin which are also found in other, non-CBD topical pain relievers. "Any cream with a heating or cooling sensation desensitizes the nerves to pain by distracting them with stimuli on top," Dr. Colberg explains. Plus you're often massaging the area as you apply, which improves circulation and reduces muscle spasms, he adds.
The wide range of benefits contained in full-spectrum CBD extracts means some CBD merchants have either ceased to sell, or scale down the promotion of CBD isolate, in comparison to the whole-plant extract variety. Companies and individuals who extract CBD themselves are realising that cannabis has more to offer medicinally than just CBD or THC, and that there is little to no reason to not include all that this "super-plant" has to offer in the extraction process.
The extract known as CBD oil sold in the U.S. falls into one of two categories. Crystalline isolate exclusively contains CBD, as other cannabinoids have been removed; full spectrum oil, on the other hand, retains THC and other cannabinoids, and is only sold in states where marijuana use has been legalized. CBD oil can be consumed several different ways, including ingested capsules and food products, vaporizing, tinctures, and topical creams. The soporific effects of CBD oil are linked to its concentration; low-concentration oils will produce minimal effects, while high-concentration oils will produce strong effects.
