"The drug produces several other conditions that make the ‘fiend’ a peculiarly dangerous criminal. One of these conditions is a temporary immunity to shock, a resistance to the knock down effects of fatal wounds… seems to be produced in the cocaine-sniffing n***o. … Once the n***o has formed the habit, he is irreclaimable. The only method to keep him from taking the drug is by imprisoning him. … For the thousands of n***oes who have not yet acquired the habit, but who will do so eventually if present conditions continue, the outlook is scarcely more hopeful."
