As a popular actor in the 1860s, Booth continued to travel extensively to perform in the North and South, and as far west as New Orleans. According to his sister Asia, Booth confided to her that he also used his position to smuggle the anti-malarial drug quinine, which was crucial to the lives of residents of the Gulf coast, to the South during his travels there, since it was in short supply due to the Northern blockade.[65]
