CBD derived from hemp contains no more than 0.3% THC and is legal federally but still illegal under some state laws. Cannabis-derived CBD products, on the other hand, are illegal federally but legal under some state laws.
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.
What is CBD?
Conclusion: Topical CBD may help relieve inflammation and excessive sebum production associated with acne but more trials are needed.
Conclusion: CBD shows promise for improving the quality of life in people with Parkinson’s disease but larger trials are needed.
Unfortunately, few human trials investigating the use of CBD as a single agent to relieve pain exist, with most trials using a combination of CBD and THC to relieve pain. Notably, Health Canada has approved a combination medication that contains both THC and CBD in a 1:1 ratio for the relief of central nerve-related pain in multiple sclerosis, and cancer pain that is unresponsive to optimized opioid therapy.
Since CBD has been studied and seen as a new drug, it is illegal to include it in food or dietary supplements or products marketed as therapeutic products. Cannabidiol is only to be included in cosmetic products, and THC contained in CBD products should be less than 0.3%  .
Since 2001, the US government has been aware of the antioxidant properties in the treatment of neurodegenerative diseases like Parkinson’s disease, Alzheimer’s disease, dementia, and HIV because these diseases are caused in part due to free radicals and when the body’s cellular system breaks apart.
Is CBD Legal?
Hence, though CBD and THC share almost the exact formula, they have a difference in the molecular structure that gives every compound unique medicinal properties. CBD has a hydroxyl group while THC has a cyclic ring that gets you high, while CBD, on the other hand, does not. Hence, CBD can moderate the effects of THC  by alleviating anxiety and stress, giving you clarity and not high.
Most skin products meant to heal skin conditions like psoriasis and eczema have anti-inflammatory properties, and so does CBD. Thanks to the powerful antioxidant properties in CBD oil, it helps fasten the skin’s healing time  .
It does this without further increasing the probability of addiction, or inducing any side effects, or getting the patient high. CBD will act as a natural non-addictive, non-psychoactive solution for overcoming opioid withdrawal and reduce any chance of relapse.
Dr. Smita Das, chair of the American Psychiatric Association’s Council on Addiction Psychiatry’s cannabis work group, does not recommend CBD for anxiety, PTSD, sleep or depression. With patients turning to these to unproven products, she is worried that they may delay seeking appropriate mental health care: “I’m dually concerned with how exposure to CBD products can lead somebody into continuing to cannabis products.”
More than 60 percent of CBD users were taking it for anxiety, according to a survey of 5,000 people. Does it help?

Does CBD help sleep and depression?
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.”
Many soldiers return home haunted by war and PTSD and often avoid certain activities, places or people associated with their traumatic events. The Department of Veterans Affairs is funding its first study on CBD, pairing it with psychotherapy.
Cannabidiol and THC are just two of the plant’s more than 100 cannabinoids. THC is psychoactive, and CBD may or may not be, which is a matter of debate. THC can increase anxiety; it is not clear what effect CBD is having, if any, in reducing it. THC can lead to addiction and cravings; CBD is being studied to help those in recovery.
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.
