CBD, or cannabidiol, is the second most abundant cannabinoid in the cannabis plant and the most prevalent in hemp. Unlike THC, CBD does not produce psychoactive effects or a "high," making it appealing to people seeking the therapeutic benefits of cannabis without intoxication. CBD has gained massive popularity in recent years, with products ranging from oils and capsules to topicals and edibles now available in most countries worldwide.
What Is CBD?
CBD (cannabidiol) is a naturally occurring compound found in the resinous flower of cannabis. It was first discovered in 1940 by American chemist Roger Adams but its structure was not fully elucidated until 1963 by Raphael Mechoulam. CBD is one of over 100 phytocannabinoids identified in the cannabis plant and typically accounts for up to 40% of the plant's extract.
Unlike THC, CBD does not bind strongly to CB1 receptors in the brain, which is why it does not produce intoxicating effects. Instead, CBD interacts with multiple receptor systems in the body, including serotonin receptors (5-HT1A), vanilloid receptors (TRPV1), and GPR55 receptors, which helps explain its wide range of potential therapeutic effects.
How CBD Works in the Body
CBD works through multiple mechanisms of action in the body. It modulates the endocannabinoid system by inhibiting the enzyme FAAH (fatty acid amide hydrolase), which breaks down anandamide — the body's natural "bliss molecule." By slowing anandamide breakdown, CBD effectively increases endocannabinoid levels in the body.
CBD also interacts with serotonin receptors, which may explain its reported anti-anxiety and antidepressant effects. Its interaction with TRPV1 receptors contributes to its pain-modulating and anti-inflammatory properties. This multi-target pharmacology is why CBD has shown promise across such a diverse range of conditions.
Benefits of CBD
Research has identified numerous potential therapeutic applications for CBD:
Types of CBD Products
The CBD market offers products in several categories:
1. CBD oils and tinctures: Liquid extracts taken sublingually for rapid absorption 2. CBD capsules and softgels: Pre-measured doses for consistent daily supplementation 3. CBD edibles: Gummies, chocolates, and beverages infused with CBD 4. CBD topicals: Creams, balms, and patches applied directly to the skin for localized relief 5. CBD vape products: Inhalable CBD for fast-acting effects
Products are further categorized by spectrum: full-spectrum (contains all plant compounds including trace THC), broad-spectrum (THC removed), and CBD isolate (pure CBD only).
CBD Dosing Guidelines
There is no universal CBD dose, as optimal amounts vary by individual, condition, and product type. General guidelines suggest starting with 10–25 mg per day and gradually increasing until desired effects are achieved. Most clinical studies have used doses ranging from 25 mg to 1,500 mg per day depending on the condition being treated.
Factors that influence optimal dosing include body weight, individual metabolism, the severity of the condition, and the product's bioavailability. Sublingual oils typically have higher bioavailability (13–35%) compared to oral products like capsules (6–15%).
Side Effects of CBD
CBD is generally well-tolerated, but possible side effects include drowsiness, dry mouth, reduced appetite, diarrhea, and fatigue. CBD can also interact with certain medications by inhibiting cytochrome P450 enzymes in the liver, similar to grapefruit juice. Always consult a healthcare provider before using CBD, especially if taking prescription medications.
