Levonantradol (CP 50,556-1) is a synthetic cannabinoid analog of dronabinol (Marinol) developed by Pfizer in the 1980s. It is around 30x more potent than THC, and exhibits antiemetic and analgesic effects via activation of CB1 and CB2 cannabinoid receptors.[1] Levonantradol is not currently used in medicine as dronabinol or nabilone are felt to be more useful for most conditions, however it is widely used in research into the potential therapeutic applications of cannabinoids.[2][3][4]
