Cannabis Is Our Friend
Cannabis (also known as marijuana) is a family of flowering plants that can be found in three types: sativa, indica, and ruderalis. Cannabis is widely used as a recreational drug, behind only alcohol, caffeine and tobacco in its usage. It typically consumed as dried flower buds (marijuana), as a resin While the three varieties of cannabis (sativa, indica, and ruderalis) may look very similar, pharmacologically they have very different properties. Cannabis sativa is often reported to cause a “spacey” or heady feeling, while Cannabis indica causes more of a “body high”. Cannabis ruderalis, by contrast, is less well used due to its low Tetrahydrocannabinol levels.
Tetrahydrocannabinol (or THC) is one of the principle psychoactive components in Cannabis. It a chemical that is believed to be a plant defensive mechanism against herbivores. THC is a cannabinoid, a type of chemical that attaches to the cannabinoid receptors in the body, and it is this pathway that many scientists are exploring for future neuroprotective therapies for Parkinson’s disease.
A second type of cannabinoid is Cannabidiol (or CBD). CBD is considered to have a wider scope for potential medical applications. This is largely due to clinical reports suggesting reduced side effects compared to THC, in particular a lack of psychoactivity.
