Struggling with stress, insomnia, migraines, or skin problems? Many claim a few drops of CBD oil under the tongue can make symptoms vanish. But does it truly deliver?
Imagine waking up refreshed after weeks of fatigue or finally sleeping through the night despite stress—CBD oil is often hailed as a natural remedy for these issues, as well as mood swings, joint pain, migraines, and even serious conditions like cancer, Parkinson's, and rheumatism. Online testimonials abound, and drugstores stock it widely. But what's in this hemp-derived oil, and how does it actually work?

Cannabis researcher Arno Hazekamp explains: “CBD stands for cannabidiol, extracted from the flower buds and leaves of the hemp plant. Hemp is legally cultivated for its fibers and is often confused with marijuana.” Both belong to the cannabis family, but hemp contains little to no THC—the psychoactive compound in marijuana—while being rich in CBD. Available in pharmacies since 2007, CBD is promoted for its relaxing, pain-relieving effects and potential to boost energy. Unlike THC, CBD is non-psychoactive, non-addictive, and legal, as it doesn't fall under the Opium Act.
Weed or THC oil requires a prescription for severe illnesses. CBD interacts with the body's endocannabinoid system—a key part of our nervous system. Plant cannabinoids in the oil mimic our own, binding to the same receptors. This is the basis for claims that it reduces pain, inflammation, improves digestion, and promotes relaxation.
CBD oil gained massive popularity after a 2013 CNN documentary on Charlotte Figi, a 5-year-old with severe epilepsy who experienced hundreds of seizures weekly. Her parents tried CBD oil as a last resort, and she improved dramatically.
Hazekamp confirms: “Studies show long-term benefits for certain epilepsies, helping about 25% of patients.” But is CBD a proven medicine for all claimed benefits? “The market has outpaced research and regulation,” he notes. “Millions use it worldwide, but its status as medicine or supplement remains unclear for most conditions. Epilepsy shows promise, but evidence for stress, rheumatism, or migraines is preliminary. Rigorous clinical trials take years.”
Many online sellers make unverified claims, which the Nutrition Center warns against: “No proven health benefits allow such statements.” Sellers often sidestep by suggesting you 'Google it.' Notably, the WHO deems pure CBD safe.
Hazekamp cautions about product quality amid rapid popularity. Extracting CBD is straightforward but unregulated, with many labs—often abroad—popping up unchecked. EU and UN discussions on oversight are ongoing; the Nutrition Center views it as a supplement awaiting stricter rules.
The CBD market lacks transparency: pesticide residues, lab purity, and exact CBD/THC levels vary. Hemp naturally contains trace THC (capped at 0.05% to stay legal). Hazekamp's 2017 analysis of 46 oils found some with no CBD—just olive oil—or inaccurate dosing. “It's like Russian roulette,” he says. “Labels are unreliable, and quality seals absent.”
Does he advise against it? “No. CBD is a popular herbal remedy that helps some, like vitamin C does for others. It's non-addictive, plant-based, and hard to overdose on—if it doesn't help, it likely won't harm. Don't expect miracles.”
For trials, buy from pharmacies or shops, not online: “Retailers prioritize quality for reputation and offer support.” If you feel benefits in two weeks, it may work for you; otherwise, it probably won't.
Made from hemp leaves and flowers with 1.7% cannabidiol, this tea is said to support immunity and promote restful sleep.
These candies mask CBD oil's taste, with 2.5 mg cannabidiol per drop in 18 flavors.
For irritated, dry skin, this ointment's CBD aims to aid recovery and calm inflammation.
Skin absorption of CBD from soap is questionable, but it ensures a clean result regardless.
Taking CBD oil abroad? Hazekamp warns: Even with ≤0.05% THC, customs tests could flag it, leading to smuggling charges—as happened to travelers in Croatia and Russia.
In 2017, Radar surveyed 6,000 users: 40% for joint pain, 37% sleep issues, 34% chronic pain, 17% nerve pain, 10% psychological complaints, 8% skin/tingling issues, 7% blood pressure. Half felt 'some' benefit; 30% none; 17% strong relief. A few reported worsening.
