The experts on Coca and Cocaine during the 1800's spanned the globe. Germany had Karl Koller, E. Merck, Sigmund Freud, Louis Lewin, France had, Angelo Mariani, Britain had Dr Robert Christison, William Martindale and Richard Spruce(33 ).

In 1890 some began to have concerned over public health and safety and the use of Cocaine. Also the legal supply of Cocaine increased roughly 700 percent from 1890 to 1902(34).

Coca-Cola stopped using Cocaine as an ingredient in 1903(35 ).

Ernest Shackleton took 'Forced March' brand of cocaine tablets to Antarctica in 1909, as did Captain Scott a year later (36 ).

A medical Journal of the time said about Cocaine and blacks, "The planters therefore hold out every encouragement to the negro hands to put in a big day's work. The negroes found that the drug enabled them to work longer and make more money, and so they took to it." And it concluded "[Cocaine] use has grown steadily. On many of the Yazoo plantations this year the negroes refused to work unless they could be assured that there was some place in the neighborhood that they could get cocaine, and one big planter is reported to keep the drug in regular stock among the plantation supplies and to issue regular rations of cocaine just as he was accustomed in the past to issue rations of whiskey."(37 ).

Medical journals started to report on a "Negro cocaine menace,", newspapers across the south ran stories like 1899 the Chattanooga Times story that said Cocaine users are "the lowest, most criminal and depraved portion of any city's population". Georgia's Colonel J. W. Watson wrote in a northern publication in 1903,"I have given the cocaine question considerable study," and continued, "and I am satisfied that many of the horrible crimes committed in the southern States by the colored people can be traced directly to the cocaine habit.". An 1901 Atlanta Constitution article said "Use of the drug among negroes is growing to an alarming extent," and also said "It is stated that quite a number of the soft drinks dispensed at soda fountains contain cocaine, and that these drinks serve to unconsciously cultivate the habit."(38 ).

An official from Pennsylvania's State Pharmacy Board said "most of the attacks upon the white women of the South are the direct result of a cocaine-crazed Negro brain."(39 ).
