Heroin is synthesized from what drug?

Explanation:
Heroin is a diacetylated form of morphine, synthesized from morphine by acetylation. The addition of two acetyl groups makes the molecule more lipophilic, so it crosses the blood-brain barrier much more quickly than morphine, producing a faster and more intense onset of effects. In the brain, heroin is rapidly deacetylated to 6-monoacetylmorphine and then morphine, which drives its pharmacologic actions. The other substances listed are unrelated to heroin synthesis: diazepam is a benzodiazepine, ecgonine is a component associated with cocaine chemistry, and chlorpromazine is an antipsychotic.
