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.
Since the UK, for example, had never officially banned absinthe, they began importing the spirit again in the â90s. Meanwhile, in the US, there had been an official ban. So from 2004-2007, Absinthe brands KÃ¼bler and Lucid Absinthe SupÃ©rieure worked with their lawyers to make absinthe effectively legalized in the US. In short, absinthe was never dangerous â no more than chugging vodka or shooting Fireball.
