Hemp, on the other hand, is harnessed as seed, oil and fibre to produce a wide range of products. It is cultivated to produce a low concentration of the psychoactive cannabinoid THC – as well as higher levels of the non-psychoactive cannabinoid CBD.
Billy had flown with his mother to Canada to buy the CBD oil – which helps to keep his daily epileptic seizures at bay. But his oil was confiscated because it was made from cannabis flowers and leaves, and so was classed as illegal in the UK, pushing childhood epilepsy and CBD oil into the spotlight.
Cannabis is classified as hemp if it has a maximum level of 0.2% THC. Billy’s CBD oil, confiscated at Heathrow, was made from cannabis with a higher level than 0.2% of THC – so it was classed as cannabis, which is why it was confiscated.

In Billy Caldwell’s case, the home secretary, Sajid Javid, made the decision to grant Billy access to imported CBD oil. This fresh approach to reconsider the classification of cannabis has been seminal, and mirrors wider sentiment in other countries. In the US, for example, medical cannabis programmes have been initiated in 30 states. Hence, medical tourism to Canada – where cannabis is legal for medicinal purposes – and the US to gain access to CBD oil.
So far, so confusing, but part of the problem is that terms like cannabis and hemp are often used interchangeably – which masks the nuances and complexities of the cannabis plant.

When people talk about hemp oil, they're referring to oil extracted from the seeds of the hemp plant. There are no cannabinoids—CBD or THC—in hemp oil. This ingredient is packed with healthy fats and often appears in beauty products for its moisturizing benefits.
This is a confusing one for many people. "A lot of brands don't do a good job of clearly instructing their consumer on the dosing," says Chris Roth, CEO and co-founder of Highline Wellness. When thinking about dosing, also consider whether your CBD is full-spectrum or isolate: Full-spectrum could include other cannabinoids like cannabidivarin or cannabigerol (this is important, since "there's something called the 'entourage effect' when all together, they're more effective than any one of them alone," Roth explains), while isolate is 100% CBD. "Some people might only need 10 milligrams of full-spectrum CBD, but with isolate, even taking 80 or 100 milligrams might not have the same effect," he says.
Still, is CBD worth trying for pain management?
It really depends on what your goal is and why you're taking CBD in the first place.
The biggest differences between tinctures, edibles, and vape pens are speed of delivery and how long the effects last. Vape relief is faster but wears off faster too—usually in about two hours, says Dr. Chin. "Say you wake up in the morning and pulled your back out, you might want to take CBD through a vape pen, which delivers in 10 minutes."
You've probably heard the terms cannabis, marijuana, and hemp all tossed around in relation to CBD. The plant Cannabis sativa has two primary species, hemp and marijuana. Both contain CBD, but there's a much higher percentage in hemp, which also has very low (less than 0.3%) levels of THC compared to marijuana.
CBD is readily obtainable in most parts of the United States, though its exact legal status is in flux. All 50 states have laws legalizing CBD with varying degrees of restriction, and while the federal government still considers CBD in the same class as marijuana, it doesn’t habitually enforce against it. In December 2015, the FDA eased the regulatory requirements to allow researchers to conduct CBD trials. Currently, many people obtain CBD online without a medical cannabis license. The government’s position on CBD is confusing, and depends in part on whether the CBD comes from hemp or marijuana. The legality of CBD is expected to change, as there is currently bipartisan consensus in Congress to make the hemp crop legal which would, for all intents and purposes, make CBD difficult to prohibit.
Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does. A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements. So, you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. In addition, the product may contain other (unknown) elements. We also don’t know the most effective therapeutic dose of CBD for any particular medical condition.
Is cannabidiol legal?
CBD is commonly used to address anxiety, and for patients who suffer through the misery of insomnia, studies suggest that CBD may help with both falling asleep and staying asleep.
CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis. Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat. More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control.
CBD stands for cannabidiol. It is the second most prevalent of the active ingredients of cannabis (marijuana). While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, which is a cousin of the marijuana plant. While CBD is a component of marijuana (one of hundreds), by itself it does not cause a "high." According to a report from the World Health Organization, "In humans, CBD exhibits no effects indicative of any abuse or dependence potential…. To date, there is no evidence of public health related problems associated with the use of pure CBD."
