A high concentration of thujone in alcohol has negative effects on attention performance. It slowed down reaction time, and subjects concentrated their attention in the central field of vision. Medium doses did not produce an effect noticeably different from plain alcohol. The high dose of thujone in this study was larger than what one can get from current beyond-EU-regulation "high thujone" absinthe before becoming too drunk to notice, and while the effects of even this high dose were statistically significant in a double blind test, the test subjects themselves could still not reliably identify which samples were the ones containing thujone. The deleterious effects of absinthe as well as its hallucingenic properties are a persistent myth often repeated in modern books and scientific journals with no evidence for either.
psst...Thujone (C10H16O) is the "secret ingredient", the active chemical in wormwood, most notably the Artemisia absinthium. Anybody who enjoys even vaguely hallucinogenic experiences from drinking absinthe (regardless of how much wormwood is in it) is in fact experiencing "the placebo effect" and is someone that we in England would call, "a cheap night out"
