Thebaine

A minor constituent of opium, thebaine or paramorphine (C19H21NO3) is chemically similar to both morphine and codeine, but produces stimulatory rather than depressant effects. Thebaine is not used therapeutically, but is converted into a variety of compounds including codeine, hydrocodone, hydromorphone, oxycodone, oxymorphone, nalbuphine, naloxone, naltrexone, buprenorphine and etorphine. It is controlled in Schedule II of the Controlled Substances Act as well as under international law.
