Full Spectrum vs. Broad Spectrum
Full-spectrum CBD contains several components of the cannabis plant, including trace amounts of tetrahydrocannabinol (THC). Federally legal full-spectrum products will always have less than 0.3 percent THC. In states where cannabis is fully legal, you may also be able to find full-spectrum products with higher THC levels.
Broad-spectrum CBD. This type of CBD does not contain THC. It does contain other components of the cannabis plant, though, so it won’t be 100 percent CBD. Consider it the middle child of the three CBD choices.
Cannabinoids
Cannabinoids are compounds found in the cannabis plant or synthetic compounds that can interact with the endocannabinoid system. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC), the primary intoxicating compound in cannabis.
Terpenes.
Terpenes are naturally occurring chemical compounds found in plants and some animals. They’re responsible for the aromas, flavors, and even colors associated with various types of vegetation. In terms of cannabis, terpenes are what make certain strains smell or taste different from others.
