Food and Drug Administration approved the CBD-based drug Epidiolex, used to treat severe epilepsy, especially Lennox-Gastaut syndrome and Dravet syndrome, two of the most debilitating forms of the disease in children.
U of A pharmacy researcher Raimar Loebenberg said he is eager to contribute to the nascent body of clinical data. He has started exploring the analgesic properties of CBD topical creams to see whether the hype is justified. Producers of the cream claim it relieves muscle soreness. Some reports even suggest it can be effective in combatting skin cancer, said Loebenberg. One big problem with unregulated CBD products, he said, is unreliable quality and inconsistent dosing. Some producers may also fail to recognize the pharmaceutical complexity of the marijuana plant, and the way in which its cannabinoids interact with the endocannabinoid receptors in our bodies.
It could prove that isolating any one cannabinoid for medical purposes is in some cases self-defeating. Medical researcher Jason Dyck has recently acquired the largest known database of medical cannabis users in the world, containing information on about 40, medical cannabis patients in Ontario, and has just begun searching for patterns. An expert on the medical properties of plants, Dyck agrees the brightest prospects for cannabis lie in more complex combinations of its compounds.
Other bioactive agents, such as terpenes, responsible for marijuana's flavour and odour, may play a significant part in targeting whatever ails us, he said. Method of ingestion can also make a difference in the efficacy of the drug, said Loebenberg. Oils, capsules and sublingual tinctures are popular, but not necessarily the most reliable way to deliver potency.
Powder or mist inhalers, similar to Ventolin dispensers used for asthma, allow for CBD delivery with precise dosing, relying on neither heat vaping nor combustion smoking. So far, however, the devices are unavailable in Canada. Looking ahead, Loebenberg added the potential benefits of medical cannabis have been neglected for far too long, and that it's high time science caught up with cannabis culture. They gave a very important medical plant away to criminals. That's why I'm shifting a lot of my research in this direction, because the opportunity is just too good.

The following is a summary of the research on several neurological conditions in which CBD has been investigated. One of the most highly studied uses for CBD is in seizure treatment for epilepsy patients.
In the first large-scale multi-center study was presented on patients with Dravet syndrome, Lennox-Gastaut syndrome and several other intractable pediatric epilepsies. Results showed a median reduction in seizures of Limitations of this study included a lack of control group, an open-label observational nature and a short follow up of only 12 weeks.
In an Israeli study of 74 patients were treated with an oil containing a Study limitations included a lack of control group, reliance on parental report for seizure activity a short duration of the study and lack of measurement of other drug levels. In May , a double-blind, placebo-controlled trial by Devinsky et al was published in the New England Journal of Medicine. In March , a randomized, double-blind, placebo-controlled trial was conducted at 24 clinical sites with participants in the United States, the Netherlands, and Poland.
This study reported a reduction in monthly drop seizures of Reported side effects were minor and similar to previously described studies. An ongoing open-label extension of this trial aims to understand the dose-response effect as well as the long-term efficacy of this therapy. This approval was specifically for the treatment of Lennox-Gastaut syndrome and Dravet syndrome, which are both severe forms of epilepsy that are often resistant to normal epilepsy medicine.
The preclinical evidence strongly supports CBD as a potential treatment for generalized anxiety disorder, panic disorder, social anxiety disorder, obsessive-compulsive disorder, and post-traumatic stress disorder PTSD. This has been limited to acute administration rather than long-term use. Few human studies have yet investigated chronic CBD dosing and more research is needed in this area.
A study using rats indicated that cannabidiol could disrupt the consolidation of specific and generalized fear memories. This study may help researchers understand the mechanism behind the effects in the endocannabinoid system, and may hold promise for sufferers of PTSD and other anxiety-related disorders. There is early evidence that cannabinoids have potential for treating autism or autism spectrum disorder ASD , a neurodevelopmental disorder that develops in infancy or childhood.
The main symptom of ASD is impaired social interaction. Early signs can include unresponsiveness to people, avoiding eye contact or failure to respond to their own names. Researchers have found a potential link between autism and the cannabinoid 2 CB 2 receptors in the brain. Pennsylvania and Minnesota are the only states as of July to have approved medical cannabis treatments for autism.
Research and evidence are still limited on this condition, with no large-scale clinical study results available and only single case study reports and animal research published to date. Schizophrenia is characterized by deficits in learning, memory, attention and executive functioning, and it can severely impact daily living.
