Cannabicitran (CBTC) is a phytocannabinoid first isolated in 1974 as a trace component of Cannabis sativa,[1][2][3][4] Structurally related compounds can be found in some other plants.[5][6] It is not psychoactive, but was found to reduce intraocular pressure in tests on rabbits,[7] which may reflect agonist activity at the NAGly receptor (formally GPR18) that is known to be a target of many structurally related cannabinoids.[8]
