CBD
Redirected from "Cannabidiol"
Also known as: Cannabidiol
Cannabidiol (CBD) is one of many cannabinoids found in Cannabis sativa. Unlike delta-9-tetrahydrocannabinol (THC), CBD does not usually produce the characteristic cannabis "high," but it is biologically active and can cause adverse effects and drug interactions. CBD is not the same as cannabis, THC, hemp-seed oil, or a standardized prescription medicine merely because those products may share a plant source.
Commercial CBD is sold as oils, capsules, foods, cosmetics, and topical products. An isolate is intended to contain CBD alone, whereas broad- or full-spectrum extracts may contain other cannabinoids and plant compounds; terminology and legal limits vary by market. The route of administration changes how much reaches the circulation. A topical label, for example, does not establish that enough CBD enters deep muscle or joint tissue to produce a systemic effect.
CBD is marketed to athletes for pain, muscle soreness, sleep, and recovery, but controlled human research in exercise settings is sparse. A 2024 systematic review of CBD and athletic recovery found limited, inconsistent evidence and no basis for a general performance or post-exercise recommendation. Subjective relaxation or a laboratory mechanism is not proof that CBD repairs tissue, improves sleep quality, or restores performance. A purified prescription CBD medicine is approved for specific seizure disorders in some jurisdictions; its evidence, dose, quality control, and monitoring cannot be transferred to an over-the-counter wellness product.
CBD can cause drowsiness, diarrhea, reduced appetite, and mood or alertness changes. It can affect liver enzymes and alter the action or concentration of other medicines; combining it with alcohol or other sedating substances can increase impairment. The US Food and Drug Administration's CBD safety overview also highlights possible liver injury and substantial unknowns around sustained use. Pregnancy, breastfeeding, liver disease, use of medication, and persistent pain or sleep symptoms require qualified assessment rather than substituting CBD for established care.
Label accuracy is a central product issue. An oil may contain less or more CBD than stated, undeclared THC or other cannabinoids, pesticides, solvents, or heavy metals. A batch-specific certificate from an independent accredited laboratory is more informative than "THC-free" marketing, though it cannot remove every risk. Laws also vary by country.
For drug-tested athletes, the distinction is critical: the current World Anti-Doping Agency Prohibited List excepts CBD itself but prohibits other natural and synthetic cannabinoids in competition, including THC. Contaminated or full-spectrum CBD can therefore still lead to a positive test. Athletes remain responsible for what enters their body and should check the current rules rather than relying on the front label of a supplement.
