Because CBD oil products are mostly unregulated, there’s no guarantee that any given product contains a safe or effective level of CBD. In fact, a study published in the Journal of the American Medical Association in 2017 found that nearly 70 percent of all CBD products sold online are incorrectly labeled, and could cause serious harm to consumers. Some CBD oils may also contain incorrectly labeled amounts of THC and other compounds.
CBD derived from marijuana is a different story, and the law varies from state to state. But as long as you’re using CBD oil that contains less than 0.3 percent THC, you have nothing to be concerned about anywhere in the United States. On the other hand, if you want to take your CBD on a trip outside the country, definitely look into local laws to avoid getting into awkward situations while you’re away.
CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
Martin Lee, co-founder of Project CBD, told Leafly that hemp fiber and seed contain no usable amounts of cannabinoids. “Cannabidiol can’t be pressed or extracted from hempseed,” he writes. “CBD can be extracted from the flower, leaves, and, only to a very minor extent, from the stalk of the hemp plant. Hemp oil start-ups lack credibility when they say their CBD comes from hempseed and stalk.”
These are one of the most popular (and effective) choices for arthritis and other forms of localized pain and inflammation. Since the skin acts as an excellent semi-permeable membrane that “let’s the good stuff and keeps the bad stuff out,” rubbing CBD-infused creams into the affected area has proved to be quite effective in terms of both pain and inflammation reduction.
Seizure disorder (epilepsy). A specific cannabidiol product (Epidiolex, GW Pharmaceuticals) has been shown to reduce seizures in adults and children with various conditions that are linked with seizures. This product is a prescription drug for treating seizures caused by Dravet syndrome or Lennox-Gastaut syndrome. It has also been shown to reduce seizures in people with tuberous sclerosis complex, Sturge-Weber syndrome, febrile infection-related epilepsy syndrome (FIRES), and specific genetic disorders that cause epileptic encephalopathy. But it's not approved for treating these other types of seizures.
Working with farms in Northern Europe, we carefully tested and reviewed 3,000 cultivars to find the one that would thrive and produce the optimal ratio of cannabinoids necessary for our products. The oil sourced from these plants are high in CBD and low in THC, the cannabinoid that gets users high, making our extracted hemp oil products legal to purchase in the U.S.
Though reviews are mixed, the majority of reviewers have reported positive experiences, mainly in regard to sleeplessness and stress. Other positive reviewers have cited assistance with muscle tension and pain. One reviewer stated that following prolonged use, the need for anti-inflammatory medication was eliminated. Surprisingly, the majority of negative reviews cite an unfavorable taste more often than decreased effects. Other negative amazon reviews site problems with shipping, and disappointment that the product is not a full spectrum hemp oil containing CBD.
This review paper on the safety and side effects of cannabidiol by the NCBI, for example, suggests that controlled cannabidiol administration is safe and non-toxic in humans and animals. It also does not induce changes in food intake, nor does it affect physiological parameters like heart rate, body temperature or blood pressure. Also, according to this review paper, “high doses up to 1,500 mg/day of CBD are reportedly well tolerated in humans.”

CBD oil has gained the most traction among the general public for its ability to treat psychiatric conditions like anxiety and addiction. The roots of CBD oil in psychological treatment originated from its surprising effectiveness at helping children with epilepsy, and it’s becoming increasingly popular as a way to help ameliorate symptoms in children with autism spectrum disorder as well.
Customer Service: It’s difficult to find contact information on Calm by Wellness’s website, and their email address is listed incorrectly in two places (we tried sending them an email but it was not delivered). We were, however, able to get a response through Facebook, and the company does offer free shipping and a generous 30-day return policy on all orders.
The unflavored oil is derived from organic hemp seed oil. It is considered both vegan and gluten-free, and does not have any artificial sweeteners or preservatives. The oil contains 0.3% THC, meaning those who face the possibility of drug tests may want to avoid taking it, but this relatively small amount produces little, if any, psychoactive effect. The price per mg is $0.11, making the Spruce Lab Grade CBD Oil less expensive than average.
Best CBD on Amazon. Currently, Amazon states they do not allow the sale of CBD products on their platform, as it is listed as a prohibited product. However, there are plenty hemp derived CBD oils on Amazon to choose from, many show casing their ability to relieve symptoms of pain, anxiety, sleep and depression. The health benefits of cannabis derived CBD oils tend to surpass those of hemp derived CBD oils, as the oils are derived from different parts of the hemp plant. Even so, the derived CBD is virtually the same and provides an array of benefits.
