Hupyrian beetle snuff
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 2151, Ulis offered his cousin Krem his beetle snuff collection in exchange for his freedom. Krem declined, noting that it made him sneeze. ()

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. ()

During Zek's captivity in the mirror universe in 2375, he introduced Regent  to beetle snuff, which he took a liking to. ()
