CBD
Cannabidiol
CBD is the second most abundant cannabinoid in cannabis and the most researched non-psychoactive compound. Derived from both hemp and marijuana plants, it works through a remarkable multi-target mechanism — modulating the endocannabinoid system, serotonin receptors (5-HT1A), TRPV1/TRPA1 channels, GABA pathways, PPARγ nuclear receptors, and the FAAH enzyme — rather than directly binding CB1 receptors.
In Simple Terms
CBD is the 'medicine' part of cannabis — it calms you down without getting you high. It's great for anxiety, pain, inflammation, and seizures (it's even FDA-approved for epilepsy). Think of it as the relaxing, healing side of the plant.
Profile
HybridWhat It Does
CBD inhibits FAAH (raising anandamide levels), acts as a strong 5-HT1A agonist (primary anti-anxiety mechanism, confirmed by a 2025 Biochemical Pharmacology review), desensitizes TRPV1/TRPA1 pain channels, acts as a negative allosteric modulator at CB1 (reducing THC's potency), antagonizes GPR55, and activates PPARγ for anti-inflammatory gene expression. A 2026 Nature study confirmed promising evidence for CBD in social anxiety, PTSD, and substance use disorders.

Interesting Facts
- •Epidiolex is the first FDA-approved cannabis-derived medicine — 2025 RCTs confirm it significantly reduces drop seizures in Lennox-Gastaut syndrome.
- •A 2025 study (Miao et al.) found CBD reverses decreased 5-HT1A gene expression via miR-16/miR-135 — a novel antidepressant mechanism.
- •CBD is in active clinical trials (NCT06672666) for anxiety and sleep, and Wayne State is testing CBD + CBT for generalized anxiety (2025).
- •A 2025 study confirmed CBD promotes apoptosis in liver, lung, gastric, and breast cancer cells via PPARγ activation.
- •CBD has a biphasic effect — low doses are stimulating, high doses are sedating.
