What makes CBD so appealing is that it’s non-intoxicating, so it won’t get you high, though it “is technically psychoactive, because it can influence things like anxiety,” Jikomes said. Although much of the marketing blitz around CBD centers on the fact that you can take it without getting stoned, there isn’t much research looking at the effects of CBD when used in isolation, with a couple of exceptions. One is the use of CBD to treat seizures: CBD is the active ingredient in the only cannabis product that the Food and Drug Administration has signed off on — a drug called Epidiolex, which is approved for treating two rare forms of epilepsy. Animal models and a few human studies suggest that CBD can help with anxiety, but those are the only conditions with much research on CBD in isolation.

While there are more unknowns than knowns at this point, Grant says he doesn’t discount all the anecdotal CBD reports. “You hear somebody say, ‘Hey, I gave this to myself and my kid and we feel a lot better,’ and we should never dismiss that kind of information,” he says. He points out that many modern medicines were discovered when researchers followed up on exactly this sort of human trial-and-error evidence. “But we still need to do the studies that confirm whether all the good things are true, and how much to give, and how to give it,” he says. “These are all questions that need to be answered.”
CBD concentrates typically contain the strongest dosage of CBD compared to any other CBD products. It can contain up to 10 times the average CBD products. Concentrates are also convenient in that it only takes a few seconds to consume. Overall, CBD concentrates seem to be most popular among customers who are extremely busy, yet seek high potency CBD.
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
Scientific studies support ashwagandha’s ability not only to relieve stress, but also to protect brain cells against the deleterious effects of our modern lifestyles. For example, in validated models of anxiety and depression, ashwagandha has been demonstrated to be as effective as some tranquilizers and antidepressant drugs. Specifically, oral administration of ashwagandha for five days showed anxiety-relieving effects similar to those achieved by the anti-anxiety drug lorazepam (Ativan®), and antidepressant effects similar to those of the prescription antidepressant drug imipramine (Tofranil®).
In the United States, non-FDA approved CBD products are classified as Schedule I drugs under the Controlled Substances Act. This means that production, distribution, and possession of non-FDA approved CBD products is illegal under federal law. In addition, in 2016 the Drug Enforcement Administration added "marijuana extracts" to the list of Schedule I drugs, which it defined as "an extract containing one or more cannabinoids that has been derived from any plant of the genus Cannabis, other than the separated resin (whether crude or purified) obtained from the plant." Previously, CBD had simply been considered "marijuana", which is a Schedule I drug.
