Hemp, marijuana and CBD are all related, but they differ in significant ways. Here’s what you need to know about their legality, effects and potential health benefits.
Another big difference among hemp, marijuana and CBD is how the law treats them.
Both hemp and marijuana belong to the same species, Cannabis sativa, and the two plants look somewhat similar. However, substantial variation can exist within a species. After all, great Danes and chihuahuas are both dogs, but they have obvious differences.
While 67% of U.S. adults support marijuana legalization, public knowledge about cannabis is low. A third of Americans think hemp and marijuana are the same thing, according to the National Institutes of Health, and many people still search Google to find out whether cannabidiol – a cannabis derivative known as CBD – will get them high, as marijuana does.
Though 15 states have now legalized recreational marijuana, it remains illegal federally in the United States. Technically, those in possession of marijuana in a legal weed state can still be punished under federal law, and traveling across state borders with cannabis is prohibited.
CBD can also block some of the intoxicating effects of THC. By binding to cannabinoid receptors, it will keep THC from activating those receptors. This translates to a less intense psychoactive effect, which is why products with a mix of CBD and THC are great for first-time consumers.

What’s the difference between CBD and THC?
With the passing of the Farm Bill in December 2018, industrial hemp became a legal agricultural commodity in all 50 states. While the DEA still considers CBD to be a Schedule I controlled substance, it clarified in a memo that trace amounts of CBD found in hemp stalks or seeds were legal.
This does not mean that CBD, by itself, cannot offer an effect. High doses of CBD often produce a profoundly relaxing experience. Like stepping out of a hot tub, your body may feel tingly and relaxed, and your brain may be clear.
A high-CBD strain would also be a great choice for someone needing to medicate throughout the day to control pain, inflammation, anxiety, or other chronic conditions.
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 has been touted for a wide variety of health issues, but the strongest scientific evidence is for its effectiveness in treating some of the cruelest childhood epilepsy syndromes, such as Dravet syndrome and Lennox-Gastaut syndrome (LGS), which typically don’t respond to antiseizure medications. In numerous studies, CBD was able to reduce the number of seizures, and, in some cases, it was able to stop them altogether. Videos of the effects of CBD on these children and their seizures are readily available on the Internet for viewing, and they are quite striking. Recently the FDA approved the first ever cannabis-derived medicine for these conditions, Epidiolex, which contains CBD.
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.
The evidence for cannabidiol health benefits
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.
Cannabidiol (CBD) has been recently covered in the media, and you may have even seen it as an add-in booster to your post-workout smoothie or morning coffee. What exactly is CBD? Why is it suddenly so popular?
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."
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.
