Codeine: Heterocyclic compound, a naturally occurring alkaloid found in opium, used in medicine as a cough suppressant and analgesic drug. It exerts its effects by acting on the central nervous system (brain and spinal cord). Chemically it is methylmorphine, the methyl ether of morphine, an alkaloid of the phenanthrene type; its action is weaker than that of morphine, and it is less likely to lead to drug addiction.

可待因:杂环化合物,鸦片中天然存在的一种生物碱。制药工业上由吗啡经甲基化制得。作用弱于吗啡,所以较不会成瘾。可口服或皮下注射,用以止痛及镇静。由于可以止咳,所以是咳嗽糖浆常见的成分。

It is a heterocyclic compound, containing a pyridine ring; its chemical formula is C10H14N. Nicotine is the chief addictive ingredient (see drug addiction)in cigarettes and cigars and in snuff. It has a unique biphasic effect: Inhaled in short puffs it is a stimulant, but when inhaled slowly and deeply it can be a tranquilizer. In larger doses, nicotine is a highly toxic poison, used as an insecticide, fumigant, and vermifuge.

尼古丁为杂环化合物,含啶环,化学式为C10H14N,是纸烟、雪茄和鼻烟中的主要上瘾成分。尼古丁有独特的二相作用,小量吸入时为兴奋剂,但缓慢且深深吸入后则为安定剂。大剂量的尼古丁有剧毒,用作杀虫剂、熏蒸剂和驱虫药。
