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.
Note that CBD oil is different from hemp oil – which comes from pressing cannabis seeds, and may not contain CBD – and hempseed oil, which is a source of essential fatty acids and contains no CBD. It’s a nutritional supplement, more like fish oil than CBD oil.
“Pure” CBD, also called “CBD isolate,” is called that because all other cannabinoids have been removed. So have terpenes and flavonoids, which give marijuana its strong aroma and earthy flavor.
One would assume, then, that hemp-derived CBD should be federally legal in every state because the THC levels don’t surpass 0.3%. But CBD occupies a legal gray area. Several states, such as Nebraska and Idaho, still essentially regulate CBD oil as a Schedule 1 substance akin to marijuana.
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.
CBD or cannabidiol oil is derived from the cannabis sativa (hemp) plant. Instead of using the seeds, CBD is extracted from the flowers, leaves, stems, and stalks of matured hemp plants. CBD oil can be extracted through several methods, including carbon dioxide, ethanol, and even olive oil. The extraction method can play a part in the quality of CBD oil.
Hemp oil should always use hemp seed oil as the active ingredient, while CBD oil should list cannabidiol, full spectrum CBD, broad spectrum CBD, hemp (not hempseed), or phytocannabinoid-rich CBD as its primary ingredient.
What is Hemp Oil?
Why does it matter? The entourage effect is the belief that the different compounds of the cannabis plant work better when they’re used together compared to being used individually. The terpenes help the cannabinoids achieve their best effects; the cannabinoids help other cannabinoids – everything works together harmoniously.
You can take CBD oil topically, or you can ingest it or take it under the tongue. When choosing a CBD oil, do not be swayed to select purely on cost, as this is one industry where you get what you pay for.
We put together a guide to help you learn about the similarities and differences between the two hemp derivatives, how to figure out what you need, and where to get the right product.
Cannabidiol (CBD) oils are low tetrahydrocannabinol products derived from Cannabis sativa that have become very popular over the past few years. Patients report relief for a variety of conditions, particularly pain, without the intoxicating adverse effects of medical marijuana. In June 2018, the first CBD-based drug, Epidiolex, was approved by the US Food and Drug Administration for treatment of rare, severe epilepsy, further putting the spotlight on CBD and hemp oils. There is a growing body of preclinical and clinical evidence to support use of CBD oils for many conditions, suggesting its potential role as another option for treating challenging chronic pain or opioid addiction. Care must be taken when directing patients toward CBD products because there is little regulation, and studies have found inaccurate labeling of CBD and tetrahydrocannabinol quantities. This article provides an overview of the scientific work on cannabinoids, CBD, and hemp oil and the distinction between marijuana, hemp, and the different components of CBD and hemp oil products. We summarize the current legal status of CBD and hemp oils in the United States and provide a guide to identifying higher-quality products so that clinicians can advise their patients on the safest and most evidence-based formulations. This review is based on a PubMed search using the terms CBD, cannabidiol, hemp oil, and medical marijuana. Articles were screened for relevance, and those with the most up-to-date information were selected for inclusion.
