Thujone is most famous for being a chemical in the drink absinthe and many modern producers list their supposed thujone levels on the bottle. At one time it was estimated absinthe contained up to 260–350 mg/L thujone,[7] but this has been shown false through testing. A 2005 study recreated three 1899 high-wormwood recipes and tested them with Gas Chromatography Mass-Spectrometry (GC-MS), the highest contained 4.3 mg/L thujone. A 1930s Pernod Tarragona was also tested and contained 1.8 mg/L thujone.[8] These results match earlier findings showing a vintage 1900s bottle contained 6 mg/L.[9] GC-MS testing is important in this capacity, because gas chromatography alone may record an inaccurately high reading of thujone because of other chemicals present that interfere and add to the apparent measured amount.[10] Through these tests it has become evident absinthe contains very little thujone.
Despite these American studies, many companies still play up the myth that traditional absinthe contains a large amount of thujone and that it will produce some sort of psychedelic effect on the drinker.
Although it contains thujone, anyone binging on absinthe would die of alcohol poisoning long before the thujone would cause any major, i.e. life-threatening, effects.[11]
