Hupyrian beetle snuff was a fine powder made of dried beetles that was a delicacy among Ferengi. It was inhaled through the nose and could often produce a fit of sneezing. It acted as a mild stimulant with some euphoric side effects. It also had a deleterious effect on the linings of the nose which was cumulative.
In 2373 Grand Nagus Zek invested a considerable amount of Ferengi wealth into a new strain of beetle that he believed would revolutionize the beetle snuff market. (DS9: "Rules of Acquisition", "Prophet Motive", "Ferengi Love Songs")
