Anxiety scores decreased in a large case series of 72 patients, with 57 patients (79.2%) reporting decreased scores within the first month after CBD treatment. 9
Unlike THC, CBD has no psychoactive properties and will not give you a “high”. There is no evidence it has any abuse or dependence potential and to date, there is no evidence that it is associated with any serious side effects, according to the World Health Organization.
Conclusion: CBD may help with depression but more trials are needed.
Conclusion: CBD is unlikely to be effective by itself for nausea and vomiting. The combination of THC and CBD does seem to be effective for nausea and vomiting.
Other trials of 300 mg of CBD in people with anxiety or depression showed that CBD appeared to preserve sleep architecture, meaning it was unlikely to have any negative effects on sleep quality. 10
Beneficial effects on anxiety after taking CBD were reported in an observational study where 21 patients out of 400 had anxiety. 8
We look at nine medical conditions where CBD may be, or, has already proven to be, beneficial.
Sleep can be disrupted for many reasons, including depression. Rodents seemed to adapt better to stressful conditions and exhibited less depressive-like behavior after taking CBD, according to a review in Journal of Chemical Neuroanatomy. “Surprisingly, CBD seems to act faster than conventional antidepressants,” wrote one of the authors of a new review, Sâmia Joca, a fellow at the Aarhus Institute of Advanced Studies in Denmark and an associate professor at the University of São Paulo in Brazil, in an email interview. Of course, it’s difficult to detect depression in animals, but the studies that Ms. Joca and her colleagues reviewed suggested that in models of chronic stress exposure, the mice and rats treated with CBD were more resilient.
A recent chart review of 72 psychiatric patients treated with CBD found that anxiety improved, but not sleep. “Over all, we did not find that it panned out as a useful treatment for sleep,” said Dr. Scott Shannon, assistant clinical professor of psychiatry at the University of Colorado, Denver and the lead author of the review in The Permanente Journal.
Cannabis containing 0.3 percent or less of THC is hemp. Although last year’s Farm Bill legalized hemp under federal law, it also preserved the Food and Drug Administration’s oversight of products derived from cannabis.
Tips for Better Sleep
But without clinical trials in humans, psychologists say CBD’s effect on depression is still a hypothesis, and not an evidence-based treatment.
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.
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.
Last year, the F.D.A. approved Epidiolex, a purified CBD extract, to treat rare seizure disorders in patients 2 years or older after three randomized, double-blind and placebo-controlled clinical trials with 516 patients that showed the drug, taken along with other medications, helped to reduce seizures. These types of studies are the gold standard in medicine, in which participants are divided by chance, and neither the subject nor the investigator knows which group is taking the placebo or the medication.

However, the effect of CBD on each addiction type was often very different. With opioid addiction, for example, CBD showed little effect in minimizing withdrawal symptoms in the absence of THC. By contrast, CBD on its own appeared effective in minimizing drug-seeking behaviors in users of cocaine, methamphetamine, and other psychostimulant drugs.

There are no guidelines for the appropriate use of CBD oil. CBD oil is usually delivered sublingually (under the tongue). Most oils are sold in 30-milliliter (mL) bottles with a dropper cap.
To use CBD oil, place one or more drops under the tongue and hold the dose there for 30 to 60 seconds without swallowing. Capsules and gummies are easier to dose, although they tend to be more costly. CBD sublingual sprays are available as well.
In addition, the stroke volume (the amount of blood remaining in the heart after a heartbeat) was significantly reduced, meaning that the heart was pumping more efficiently.
