The memory and attention impairments that are associated with the use of cannabis are one potential concern.
There are different types of CBD oil to choose from and it is unclear which CBD products might be helpful in the treatment of ADHD. These types vary depending on what they contain. CBD oil isolate contains only CBD. Broad-spectrum products contain CBD as well as other cannabinoids, but not THC. Full-spectrum products, on the other hand, contain CBD, THC, and other cannabinoids.
CBD, on the other hand, is the second most abundant cannabinoid found in the cannabis plant. Although it will not cause the high that TCH will, it does have an effect on the brain and is associated with some mental health benefits, including potential benefits for people who have ADHD.
Potential Side Effects

In an article published in the New England Journal of Medicine, Dr. Nora Volkow, director of the National Institute on Drug Abuse (NIDA), points out many of the potential negative side effects of marijuana use. Among these are impaired attention and memory, problems that can be long-term and become worse with chronic cannabis use.
The FDA warns that consumers should be wary of such claims. “This is especially concerning when companies are peddling unproven CBD products for use in vulnerable populations like infants and children,” explained FDA Acting Commissioner Ned Sharpless, M.D.
While CBD oil does not have psychoactive properties, it may also contain small amounts of THC, which could potentially exacerbate some ADHD symptoms.
“Overall, current evidence indicates CBD has considerable potential as a treatment for multiple anxiety disorders,” Dr. Blessing concludes, “with need for further study of chronic and therapeutic effects in relevant clinical populations.”
Though CBD — full name cannabidiol — is extracted from marijuana or hemp, it doesn’t contain THC, the chemical in marijuana that has psychoactive effects, so it doesn’t make you feel high.
As for effectiveness, the WHO noted that several clinical trials had shown effectiveness for epilepsy, adding: “There is also preliminary evidence that CBD may be a useful treatment for a number of other medical conditions.”
Is CBD safe?
A group of Israeli researchers have been exploring the use of CBD to reduce problem behaviors in children on the autism spectrum. A feasibility study involving 60 children found substantial improvement in behavioral outbreaks, anxiety and communication problems, as well as stress levels reported by parents.
In the US, research has been given a boost by changing guidelines and laws. In 2015 the DEA eased some of the regulatory requirements that have made CBD, as a Schedule 1 substance, difficult to study. “Because CBD contains less than 1 percent THC and has shown some potential medicinal value, there is great interest in studying it for medical applications,” the DEA said in announcing the change.
The researchers, led by Dr. Adi Aran, director of the pediatric neurology unit at Shaare Tzedek Medical Center, went on to do a double-blind, randomized, placebo-controlled trial with 150 participants with autism. In this trial, just completed but not yet analyzed, patients were treated CBD for three months.
“We’ll continue to support rigorous scientific research on the potential medical uses of marijuana-derived products and work with product developers who are interested in bringing patients safe and effective, high quality products,” the FDA pledged. “But, at the same time, we are prepared to take action when we see the illegal marketing of CBD-containing products with serious, unproven medical claims.”
