JW Booth and Quinine

[wpbinzel]

“I have only an arm to give; my brains are worth twenty men, my money worth a hundred. I have free pass everywhere. My profession, my name, is my passport. My knowledge of drugs is valuable, my beloved precious money—oh, never beloved till now!—is the means, one of the means, by which I serve the South.” … “All right,” he said lightly, “I am he [“Doctor Booth”], if to be a doctor means a dealer in quinine.”
-- Asia Booth Clarke, quoting John Wilkes Booth. Memoir. Ed. Terry Alford. Jackson: University of Mississippi Press, 1996, pp. 82-3.

In that bit of dialogue and what follows, John Wilkes Booth boasts of smuggling quinine (and possibly other drugs) to the Confederacy. Has there been research (or even a past discussion that I am unable to locate) about whether Booth actually engaged in smuggling quinine south? If so, is there any conclusion as to whether he engaged with others? The opportunity to do so on his own seems rather limited. According to Mr. Loux, between 1861-1865, Booth made four trips to Louisville (Dec. 1861, June 1862, Oct. 1862, Jan. 1864) ; one trip to Nashville (Feb. 1864); one trip to New Orleans (Mar 1864) ; and two trips to Bryantown, MD (Nov 1864 and Dec 1864). I have drawn no conclusions, and am curious if others have and why.
