While many people are aware of THC and classify it as the main active ingredient in cannabis, cannabis contains over 100 cannabinoids as well as other terpenes and flavonoids. The range of compounds create a complex chemical profile capable of producing both therapeutic and psychoactive reactions in the human body. ## **THC: Primary Active Ingredient of Cannabis** Tetrahydrocannabinol (THC) is undoubtedly the most commonly identified active ingredient cannabis contains. THC interacts with primarily CB1 receptors in the brain, producing the characteristic “high” associated with cannabis use. Although classified as psychoactive, THC has therapeutic effects to offer as well, including pain relief, anti-nausea, and appetite stimulation. The active ingredient quantities in cannabis products vary widely—certain strains only contain 5% THC while others contain above 30%, allowing people to choose their level of intoxication and relative effect. ## **CBD: Non-Intoxicating Active Ingredient Cannabis Contains** Cannabidiol (CBD) is another important active ingredient of cannabis—especially in hemp varieties. Whereas THC can provide therapeutic potential with psychoactivity, CBD can provide therapeutic potential without impairment of cognition or motor functionality. More emerging research is suggesting that CBD has anti-inflammatory, anti-anxiety, and anti-seizure properties. The ratio of THC to CBD is very important for the effect profile of any cannabis product, demonstrating precisely why the active ingredient matters for recreational users and medical patients alike. ## **Terpenes: Not Officially An Active Ingredient** Terpenes are not technically considered active ingredient cannabis compounds, but they deserve some mention. Terpenes are responsible for the unique odors associated with certain cannabis varieties, and they might influence the qualitative experience of both recreational and medicinal use as they too have a very distinct way of influencing the effect of cannabis. ## **Variability between Cannabis Strains** Different varieties of cannabis possess specific proportions and amounts of active ingredients. Historically, “[indica](/shop/options/types-indica/)” varieties contained higher relative amounts of CBD compared to “sativa” varieties, though hybridization methods have intermingled the difference more and more. What remains important is understanding the active ingredient in cannabis products so one can predict the potential effect. ## **A New Scientific Paradigm** As researchers and scientists continue to investigate cannabis compounds and their physiological interactions in humans, we are learning more and more about cannabis as a complex whole. This increasingly sophisticated understanding will eventually lead us to produce more relevant therapeutics, as well as more predictable consumer experiences, with cannabis and its active ingredients.
