Medical teams are studying former NFL and NHL players at risk for CTE – a degenerative disease caused by repetitive concussions – to see if there is benefit to athletes at high risk. Initial findings report that players participating in the study are experiencing fewer concussion complication symptoms. They will not know the true effect until the player dies. Unfortunately, there is no test for CTE. The brain can only be examined post-mortem and this is only when a diagnosis can be made.

The active ingredient CBD, extracted from the Hemp Plant, is a cousin to the Marijuana plant. It does not cause a person to experience intoxication. Intoxication comes from THC, a different component of the plant. There is some THC in CBD oil so it will show up in a urine or blood test, but only a trace amount. This is for an important reason. CBD cannot be absorbed and used by the body without THC. Think of it like milk. Vitamin D is added to milk so that the body can absorb the calcium.

Sports and CBD Research

Research and anecdotal CBD oil users are indicating that it is showing anti-inflammatory benefits as well as antioxidant properties. This is important because when the brain suffers an injury, inflammation occurs, blood flow to those areas is decreased, and brain cells die.

Our body naturally produces endocannabinoids, a molecule like the Cannabis molecule. This system plays a very important role in balancing our body. As with anything in life there needs to be balance or homeostasis. When the ECS is not in homeostasis we experience pain, and illness. Research indicates that CBD helps balance the Endocannabinoid system, which is involved in our body’s process of pain, mood, memory, sleep, stress, metabolism, immune function, and reproductive system.

The NHL Alumni group is an advocate for CBD oil. They claim that our hockey heroes of yesterday are struggling with depression, anxiety and headaches caused by physical demands on their body during their career. The most common treatment for concussion symptoms are prescribed opioids. The problem with opioids is that they are highly addictive. Some former players asked can CBD help with concussion symptoms and are turning to CBD as an alternative treatment. The anecdotal evidence is encouraging. CTV ran a story referencing neurosurgeon and concussion expert Dr. Charles Tator and his thoughts on how CBD can help manage concussion symptoms


Currently, scientists are looking at CBD use during recovery to see if it assists with the healing process as a neuroprotectant. Other findings indicate that it is effective at managing the most common concussion symptoms such as, pain management for headaches or migraines, sleep disorders, anxiety, and depression. Other areas where CBD is being studied:

First, we must know how our bodies work to understand how CBD oil can be a benefit. A newly discovered system within our body called the Endocannabinoid System (ECS), works with our immune system, nervous system, and our body’s organs. The ECS has receptors that are found all over our body including the

Cannabidiol (CBD) has been generating increasing interest in medicine due to its therapeutic properties and an apparent lack of negative side effects. Research has suggested that high dosages of CBD can be taken acutely and chronically with little to no risk. This review focuses on the neuroprotective effects of a CBD, with an emphasis on its implications for recovering from a mild traumatic brain injury (TBI) or concussion. CBD has been shown to influence the endocannabinoid system, both by affecting cannabinoid receptors and other receptors involved in the endocannabinoid system such as vanilloid receptor 1, adenosine receptors, and 5-hydroxytryptamine via cannabinoid receptor-independent mechanisms. Concussions can result in many physiological consequences, potentially resulting in post-concussion syndrome. While impairments in cerebrovascular and cardiovascular physiology following concussion have been shown, there is unfortunately still no single treatment available to enhance recovery. CBD has been shown to influence the blood brain barrier, brain-derived neurotrophic factors, cognitive capacity, the cerebrovasculature, cardiovascular physiology, and neurogenesis, all of which have been shown to be altered by concussion. CBD can therefore potentially provide treatment to enhance neuroprotection by reducing inflammation, regulating cerebral blood flow, enhancing neurogenesis, and protecting the brain against reactive oxygen species. Double-blind randomized controlled trials are still required to validate the use of CBD as medication following mild TBIs, such as concussion.
