Understanding Cannabis and Brain Health

Cannabis, often referred to colloquially as marijuana, is a complex plant that contains hundreds of chemical compounds, known as cannabinoids, with varying effects on the human body. Two of the most well-known cannabinoids found in cannabis are tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is the primary psychoactive compound responsible for the euphoric ‘high’ commonly associated with cannabis use, while CBD is non-psychoactive and has been studied for its potential therapeutic benefits.

Marijuana, the dried flowers and leaves of the cannabis plant, is the most commonly consumed form of cannabis. However, cannabis can also be consumed in various other forms, including oils, edibles, tinctures, and concentrates. Each form may have different potency levels and effects due to variations in cannabinoid concentrations and delivery methods.
