CBD (or cannabidiol) is the chemical in cannabis that is considered to have the widest scope of medical applications. It is not psychoactive so it does not result in a high however it has been shown to have anti-inflammatory, anti-anxiety, and pain-relieving effects, in addition to providing relief to various conditions involving the nervous system. CBD-heavy strains of cannabis have been used to treat conditions relating to spasms and/or seizures.
THC (or tetrahydracannabinol) is the psychoactive chemical in cannabis – in other words it is the chemical that creates the high. THC can also act as a pain reliever, and can have other effects including relaxation, alteration of visual, auditory, and olfactory senses, fatigue, and appetite stimulation. THC can be hallucinogenic and may negatively impact memory, however CBD can lessen these effects.
The human body naturally produces certain substances called endocannabinoids that play a part in a wide variety of functions including memory, appetite, energy, stress response, immune function, the nervous system, pain sensory, and sleep. The cannabis plant naturally produces a set of chemicals called cannabinoids that mimic the effects of the substances our bodies create. To date over 80 cannabinoids have been identified in cannabis, and the most commonly known are THC and CBD. Though each cannabinoid creates a specific reaction in people it’s speculated that they work best in combination with each other creating an “Entourage Effect”.
Hemp is an industrial material that is refined from the cannabis plant. It can be created from any variety of the plant, but in practice is almost exclusively made from cannabis with little to no THC content. Hemp is incredibly versatile and can be used in a wide variety of applications including paper, cloth, bio-fuel, and plastic.
Indica is a type of cannabis plant. It is typically a shorter plant than sativa with darker green leaves. Indica tends to be heavier in CBD, and the high is more relaxing.
