Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43% had more CBD than indicated, while 26% had less, and some had unexpected THC. “There’s a 75% chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.
The cannabidiol oil is derived from flowers of cannabis plants and is concentrated in its resin glands or trichomes. These glands contain oil that is rich in CBD which differs in quality and quantity between different strains of the cannabis plant. The active CBD available in the flower can be purified and concentrated using precise production techniques. When oil of high potency and concentration is derived from the glands then it can be used in lesser dosage. This lesser dosage saves money as CBD oil is an expensive product but produces the desired effect.

Not much, as far as humans are concerned—at least not yet. The vast majority of studies have been on animals, as of yet, and there are few high-quality studies on humans. Even the oil’s effect on pain—something that CBD oil is popularly used for—isn’t proven. “The studies available are small or not well designed,” says Dr. Devinsky. “There’s a lot of religion out there, but not a lot of data.”
So Herrera, who's experienced her own share of pain due to a shoulder injury followed by a bout of Lyme disease, went to a local herb shop and bought a vial of the oil, which, by some definitions, is legal in all states if it doesn't contain more than 0.3 percent THC – the psychoactive component of cannabis. She began putting seven to nine drops under her tongue first thing most mornings – and was startled by the results. "It's changed my pain level, my anxiety level and my stress level," says Herrera, who already practiced yoga, meditated regularly, ate a healthy diet and tried conventional medical treatments for pain and mobility. "It was shocking," she says, because she thought her patients' reports were due to the placebo effect. "Right now," she adds, "I feel pretty amazing."
Although it may be better to consume CBD alone than nothing at all, it may not offer you the same range of positive effects as full spectrum CBD oil. With full spectrum CBD, not only will you get adequate CBD, but you’ll also consume dozens of beneficial cannabinoids and terpenes. As a result, your body will receive more than enough vitamins, minerals, and nutrients.
