Bir\u00e7ok ara\u015ft\u0131rmac\u0131 da kokaini izole ederek dil \u00fczerindeki etkisini izah ettiler. 1884 y\u0131l\u0131nda kokainin
\nuyu\u015fturucu etkisi a\u00e7\u0131kland\u0131. Nihayet 1902 y\u0131l\u0131nda Almanya\u2019da uyu\u015fturucu olarak sentez edildi.
\nEtkileri: Kokain, sinirleri tesirsiz hale getirir ve uyguland\u0131\u011f\u0131 b\u00f6lgede uyu\u015fturma yapar. D\u00fc\u015f\u00fck dozlarla
