“Nabilone (marketed as Cesamet) is a synthetic form of delta-9-tetrahydrocannabinol (Δ⁹-THC), the primary psychoactive component of cannabis (marijuana). Although structurally distinct from THC, nabilone mimics THC’s structure and pharmacological activity through weak partial agonist activity at Cannabinoid-1 (CB1R) and Cannabinoid-2 (CB2R) receptors, however it is considered to be twice as active as Δ⁹-THC. Nabilone is approved by the FDA for the treatment of nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments.” https://www.drugbank.ca/drugs/DB00486
