Absinthe is regulated by the Food and Drug Administration and, until recently, was completely banned in the U.S. and most of Europe. The reason for this is that absinthe contains thujone, a toxic chemical found in several edible plants including tarragon, sage, and wormwood.
When drinking absinthe, it is traditionally prepared following French ritual, in which cubed sugar is slowly dissolved into the absinthe by pouring cold water over the sugar. Absinthe is flammable liquor, and it can be used in flaming cocktails. An alternate Bohemian (Czech) ritual involves fire, but does not actually light the absinthe on fire. Instead of slowly dissolving the sugar with cold water, it is doused in absinthe and lit on fire.
