Whole plant extracts also contain THC, although usually not in a large enough amount to have any psychological effects. When administered together, CBD, THC, trace cannabinoids as well as terpenes, produce what is known as an entourage effect. This synergistic relationship between cannabinoids, fatty acids and terpenes has been shown to increase the healing properties of each.
Unlike THC, which primarily binds to CB-1 receptors located in the brain, CBD works in the body by manipulating receptors throughout organ tissues, the immune system, the pain response system, the hormonal system, and other whole-body regulatory systems. Basically, since its receptors have been found to exist in virtually every cell and tissue type in the body, CBD is believed to work on every aspect of human health and behavior – from the subcellular level to the whole-body leve and beyond.
Now that CBD has become so popular, growers are creating strains of the cannabis plant that are optimized for producing high amounts of this particular cannabinoid. There are tons of new strains on the market that feature a high CBD-to-THC ratio. This makes it even easier for the processing facilities to remove the CBD and turn it into an oil extract.
Is CBD Legal? Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Check your state's laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.
