This requires making some distinctions. Though heroin, processed from poppies, and amphetamines, which are chemically synthesized, are equally important as local drugs of choice, they have very different origins and production processes. There are also differences between the groups that use them.
這中間又有所區隔：由罌粟提煉的海洛因和化學合成的安非他命，雖同樣列名台灣毒品的兩大主力，但其實兩者生產方式不一樣、產地不同，吸食族群也頗有差異，可以說是兵分南北兩路，向台灣夾擊。
