In the TV series Bridgerton, Queen Charlotte is seen sniffing a brown, powdered substance up her nose in several scenes. The substance is called snuff, which is a form of pulverized or finely chopped tobacco that is ingested by breathing through the nose. Snuff was a popular way to use tobacco in Regency England, as it was considered improper to smoke pipes or cigars in public. The real Queen Charlottes snuff habit earned her the nickname "Snuffy Charlotte". On-set, the powder that Rosheuvel snorts during filming is a dyed sugar, which is harmless.
