NEW ORLEANS. Louis J. Dufilho, Jr. opened the first licensed pharmacy in the US in 1816 in New Orleans. In 1950, the site became The New Orleans Pharmacy Museum. Not only does that site have a place in the history of US pharmacies, but it also has a place in the history of New Orleans Voodoo and Hoodoo in the US. A recent news story reported on the link between that pharmacy and New Orleans Voudoo and Hoodoo in the US.
