Thebaine (paramorphine) is an opiate alkaloid. A minor constituent of opium, thebaine is chemically similar to both morphine and codeine, but has stimulatory rather than depressant effects, causing strychnine-like convulsions at higher doses.[3] Thebaine is not used therapeutically, but can be converted industrially into a variety of compounds including oxycodone, oxymorphone, nalbuphine, naloxone, naltrexone, buprenorphine and etorphine.
It is controlled under international law, is listed as a Class A drug under the Misuse of Drugs Act 1971 in the United Kingdom and is controlled as a Schedule II of the Controlled Substances Act in America.
