In 2007 the first legally available absinthe has been approved for sale in the US. These brands must pass TTB testing, which is performed by the Gas Chromatography-Mass Spectrometry method [59] and has a margin of error of 10ppm thujone [60]. Thus brands that are under the limit 'officially' don't contain thujone even if in actuality they do. Two brands currently available are Lucid and Kübler, with more to come.
