“The widespread patient use of artisanal cannabis preparations has preceded quality validation of cannabis use for epilepsy. Neurologists and cannabinoid specialists are increasingly in a position to monitor and guide the use of herbal cannabis in epilepsy patients. We report the retrospective data on efficacy and adverse effects of artisanal cannabis in Patients with medically refractory epilepsy with mixed etiologies in Washington State, California, and Maine. Clinical considerations, including potential risks and benefits, challenges related to artisanal preparations, and cannabinoid dosing, are discussed.


Of 272 combined patients from Washington State and California, 37 (14%) found cannabis ineffective at reducing seizures, 29 (15%) experienced a 1-25% reduction in seizures, 60 (18%) experienced a 26-50% reduction in seizures, 45 (17%) experienced a 51-75% reduction in seizures, 75 (28%) experienced a 76-99% reduction in seizures, and 26 (10%) experienced a complete clinical response. Overall, adverse effects were mild and infrequent, and beneficial side effects such as increased alertness were reported. The majority of patients used cannabidiol (CBD)-enriched artisanal formulas, some with the addition of delta-9-tetrahydrocannabinol (THC) and tetrahydrocannabinolic acid (THCA). Four case reports are included that illustrate clinical responses at doses <0.1mg/kg/day, biphasic dose-response effects, the use of THCA for seizure prevention, the use of THC for seizure rescue, and the synergy of cannabinoids and terpenoids in artisanal preparations. This article is part of a Special Issue entitled “Cannabinoids and Epilepsy”.”

Long-term disease-modifying effect of the endocannabinoid agonist WIN55,212-2 in a rat model of audiogenic epilepsy.

Modulation of the endocannabinoid (eCB) transmission is a promising approach to treating epilepsy.

Animal models can be used to investigate this approach. Krushinsky-Molodkina (KM) rats have, genetically, audiogenic epilepsy. Moreover, in these animals, repeated induction of audiogenic seizures results in a progressive prolongation of the seizures, known as audiogenic kindling.

Administration of the single dose of WIN55,212-2 one hour before the 4th seizure delayed the kindling process by two weeks, without any acute effect on the audiogenic seizures.


This result suggests that short-term potentiation of the eCB system might modify the epileptogenic disease process in patients with a progressive course of epilepsy.”

“Cannabis is now apparently the cure for everything from cancer,  diarrhea, bipolar disorder and Multiple sclerosis, to an ailing economy and being a smart aleck teenager. The latest chronic illness to get the 4:20 treatment is epilepsy. British scientists from the University of Reading tested a compound in pot called cannabidivarin on rats and mice with six types of epilepsy, and found it “strongly suppressed seizures” without the unpleasant side effects of current anti-epilepsy drugs. With 1 percent of the world’s population suffering from the disease, the head of the research team, Ben Whalley, says there’s a pressing need for better treatments. “It’s a chronic condition with no cure and currently, in around one-third of cases, the currently available treatments do not work, cause serious side effects and increase fatalities,” he said.”

Compound in cannabis may help treat epilepsy, researchers say

“British researchers have determined that a little-studied chemical in the cannabis plant could lead to effective treatments for epilepsy, with few to no side effects.

The team at Britain’s University of Reading, working with GW Pharmaceuticals and Otsuka Pharmaceuticals, tested cannabidivarin, or CBDV, in rats and mice afflicted with six types of epilepsy and found it “strongly suppressed seizures” without causing the uncontrollable shaking and other side effects of existing anti-epilepsy drugs.

The casual use of marijuana — or cannabis — to control seizures dates back to ancient times. Its most prominent component, THC, is among those shown in animal studies to have strong anti-convulsant properties…”
