There is no standardized dosage of CBD. Some retailers may have enough knowledge to make a recommendation for first-timers. There are also online resources – like this dosage calculator.
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.
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.

The current federal prohibition of marijuana, in other words, does not align with the public’s view – though state-based legalization shows that society is moving on without the blessing of politicians on Capitol Hill. U.S. recreational marijuana retail sales may reach US$8.7 billion in 2021, up from $6.7 billion in 2016.
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.
If you are searching for CBD products, here are a few things to look for as you shop:
There's often confusion surrounding hemp oil and CBD oil, so let's clear one thing up first: Hemp oil is a term used by different people in different ways. Sometimes, it's used as a synonym for CBD oil, but in other cases, it's used to mean hemp seed oil, which is a different product altogether. Here are the three main distinctions between CBD oil and hemp seed oil.
One perk of hemp seed oil is that it's completely cleared by the Food and Drug Administration (FDA), and legal to buy or sell pretty much anywhere. With CBD oil, the laws are a bit trickier and vary from one state to the next. As a rule of thumb, CBD oils are legal if they contain less than 0.3% THC content. THC is the chemical compound that gives marijuana its psychoactive effects; in other words, it's the part that gets you high, which is why it's limited in all but a handful of states.

As you shop around for the best CBD oil, you'll find some CBD oils that also contain hemp seed oil for added benefits. The editors at Remedy Review, an independent CBD site, pulled together a list of CBD oils that contain hemp oil. These products come from top brands that have undergone an extensive review process that takes into account customer reviews, price, lab testing, hemp source, and more.
So, long story short: If you're looking for the most pronounced health benefits, you're better off purchasing true CBD oil as opposed to hemp (seed) oil, where CBD is minimal or non-existent and therefore cannot offer the same effects.
To begin with, be clear about whether you're actually looking for hemp seed oil, or if you want actual CBD. Make sure you thoroughly read product labels to ensure you're getting what you want. In particular, look for references to "CBD," "cannabidiol," or "full-spectrum hemp extract" on the ingredients list; if none are listed, then what you're looking at is probably hemp oil, and you shouldn't expect to receive CBD oil benefits from it. It's advisable to always spend time perusing the ingredient lists, as many hemp seed oils are misleadingly marketed to look like they are CBD products.
However, a double-blind study found healthy volunteers administered CBD had little to no change in their emotional reaction to unpleasant images or words, compared to the placebo group. “If it’s a calming drug, it should change their responses to the stimuli,” said Harriet de Wit, co-author of the study and a professor in the University of Chicago’s department of psychiatry and behavioral neuroscience. “But it didn’t.”
“If you take pure CBD, it’s pretty safe,” said Marcel Bonn-Miller, an adjunct assistant professor at the University of Pennsylvania’s Perelman School of Medicine. Side effects in the Epidiolex trial included diarrhea, sleepiness, fatigue, weakness, rash, decreased appetite and elevated liver enzymes. Also, the safe amount to consume in a day, or at all during pregnancy, is still not known.

For students with generalized social anxiety, a four-minute talk, with minimal time to prepare, can be debilitating. Yet a small experiment in the journal Neuropsychopharmacology found that CBD seemed to reduce nervousness and cognitive impairment in patients with social anxiety in a simulated public speaking task.
This year, 1,090 people have contacted poison control centers about CBD, according to the American Association of Poison Control Centers. Over a third are estimated to have received medical attention, and 46 were admitted into a critical care unit, possibly because of exposure to other products, or drug interactions. In addition, concern over 318 animals poured into the American Society for the Prevention of Cruelty to Animals’ Animal Poison Control Center.
