药品虽属商品范畴,但不同于一般商品。一般商品可以有“正品”、“副品”,“一级品”、“二级品”之分,但药品只有“有效”与“无效”之别。这是因为药品涉及到人民的身体健康、生命,是不能有丝毫马虎的。 Although drugs are in the category of commodities, they are different from general commodities. General merchandise can be divided into “genuine”, “substandard”, “primary product” and “secondary product”, but drugs are only “effective” and “invalid”. This is because medicines involve the health and life of the people and cannot be sloppy.
