"Did we say it is illegal to manufacture, or buy, or import absinthe? We meant, it was illegal. Because there is a new absinthe being marketed, made in the United States, called Lucid, and, unlike Absente, it contains thujone. As it turns out, the US laws had a little loophole of their own: Drinks were only illegal of they contained greater than 10mg of thujone per liter. And, as it turns out, most pre-ban absinthe had less than that. Lucid is based on pre-ban recipes -- it was designed by chemist Ted Breaux, a New Orleans-born fellow with a talent for reverse engineering absinthe recipes from old bottles of the stuff."
