For His Son
A father, anxious for his son's financial well being, develops a special soda pop called Dopokoke which is laced with cocaine. Dopokoke is advertised as relief "for that tired feeling." The drink is a success, but the son becomes addicted to it, much to his father's regret. Loosely based on the allegations that the Coca-Cola company and other soft drink manufacturers laced their soda with dope.
