Heroin, also known as diacetylmorphine and diamorphine among other names, [1] is a morphinan opioid substance synthesized from the dried latex of the opium poppy; it is mainly used as a recreational drug for its euphoric effects.

Heroin is a morphinane alkaloid that is morphine bearing two acetyl substituents on the O-3 and O-6 positions. As with other opioids, heroin is used as both an analgesic and a recreational drug. Frequent and regular administration is associated with tolerance and physical dependence, which may develop into addiction.

2020年10月27日 · Heroin is a very effective pro-drug of morphine (and/or 6-MAM). It's amazing, in a twisted sort of way, that heroin, the scourge of mankind (at least until fentanyl came along) is a quintessential example of the power of pro-drugs.

2017年6月12日 · In 1874, chemist C. R. Alder Wright boiled morphine with a compound called acetic anhydride, simply to see what would happen. Acetic anhydride is a fairly reactive molecule. Think of it as two...

2020年1月16日 · Heroin, not oxycodone or hydrocodone, is by far the most dangerous opiate on the street. But technically, it isn't dangerous at all. And it's not necessarily a "street" drug because It can be legal. Confused? Read on, because here's a bunch of stuff you might not know about heroin. Heroin is a pro-drug of morphine.

It follows that heroin users do not take a single drug but four (heroin, 6-MAM, morphine, and M6G), each with its distinctive rewarding profile, which might help to explain why heroin is still the most abused opioid world-wide.

Heroin, or diamorphine, is the diacetyl derivative of morphine. It is rapidly converted in the body into 6-acetylmorphine (monoacetylmorphine, MAM) and then to morphine. Heroin is a potent analgesic, five to ten times more potent morphine in this regard.

2021年3月24日 · Heroin molecule The simpler molecule is morphine and the more complex molecule is heroin, which, as we mentioned earlier, is a derivative of morphine. The -OCOCH 3 groups that replace the -OH groups in morphine are shown in red.

2023年11月22日 · Heroin’s chemical formula is C 21 H 23 NO 5. The drug is sometimes called a natural drug because it derives from poppy sap. Chemists consider it a semi-synthetic drug, as the morphine from plants must be manipulated and altered to make heroin.[3]

Heroin is a crude preparation of diamorphine. It is a semisynthetic product obtained by acetylation of morphine, which occurs as a natural product in opium: the dried latex of certain poppy species (e.g. Papaver somniferum L.). Diamorphine is a narcotic …
