Morphine is a pain medication of the opiate family that is found naturally in opium, a dark brown resin in poppies (Papaver somniferum).

Approximately 12 percent of opium is made up of the analgesic alkaloid morphine, which is processed chemically to produce heroin and other synthetic opioids for medicinal use and for the illegal drug trade.
The latex also contains the closely related opiates codeine and thebaine, and non-analgesic alkaloids such as papaverine and noscapine.
Opioid

Opioids are substances that act on opioid receptors to produce morphine-like effects.
Opioids include opiates, an older term that refers to such drugs derived from opium, including morphine itself.
Codeine
4 linksCodeine is an opiate and prodrug of morphine used to treat pain, coughing, and diarrhea.
Thebaine
2 linksThebaine (paramorphine), also known as codeine methyl enol ether, is an opiate alkaloid, its name coming from the Greek Θῆβαι, Thēbai (Thebes), an ancient city in Upper Egypt.
A minor constituent of opium, thebaine is chemically similar to both morphine and codeine, but has stimulatory rather than depressant effects.

Opium contains a class of naturally occurring alkaloids known as opiates, that include morphine, codeine, thebaine, oripavine, papaverine and noscapine.
Opioid receptor

Opioid receptors are a group of inhibitory G protein-coupled receptors with opioids as ligands.
By the mid-1960s, it had become apparent from pharmacologic studies that opiate drugs were likely to exert their actions at specific receptor sites, and that there were likely to be multiple such sites.
Social attachment was demonstrated to be mediated by the opioid system through experiments administering morphine and naltrexone, an opioid agonist and antagonist, to juvenile guinea pigs.
Dipropanoylmorphine
1 linksDipropanoylmorphine (Dipropionylmorphine in U.S. English) is an opiate derivative, the 3,6-dipropanoyl ester of morphine.
Diacetyldihydromorphine
0 linksDiacetyldihydromorphine (also known as Paralaudin, dihydroheroin, acetylmorphinol) is a potent opiate derivative developed in Germany in 1928 which is rarely used in some countries for the treatment of severe pain such as that caused by terminal cancer, as another form of diacetylmorphine (also commonly known as Heroin).
Diacetyldihydromorphine is quickly metabolized by plasma esterase enzymes into dihydromorphine, in the same way that diamorphine is metabolized into morphine.
