cocaine    音标拼音: [kok'en]
n. 古柯碱

古柯硷

cocaine
n 1: a narcotic (alkaloid) extracted from coca leaves; used as a
surface anesthetic or taken for pleasure; can become
powerfully addictive [synonym: {cocaine}, {cocain}]

Cocaine \Co"ca*ine\, n. (Chem.)
A powerful narcotic alkaloid, {C17H21NO4}, obtained from the
leaves of coca. It is a bitter, white, crystalline substance,
and is remarkable for producing local insensibility to pain.
It is classified as addictive and is not available in the U.
S. without a prescription, but is nevertheless one of the
most widespread illegal drugs of abuse. It is used in several
forms, including small pellets of free base, called {crack}.
Most of the cacaine illegally used in the U.S. is imported.
[1913 Webster PJC]
