...I've been reading up on this after hearing about someone drinking it and being disappointed that they did not experience hallucinogenic effects. Apparently what is marketed as absinthe today is not the same drink that lubricated the artsy denizens of Paris in the early 20th century. Even then, there was nothing inherent in any ingredient that would have caused hallucinations. More likely, unscrupulous bottlers but various poisons in the drink to save steps on the colorization process. These could have caused hallucinations. Even more likely, reports of the mystical, mind-opening nature of the drink were embellished by the bohemians who drank it. Regardless, I found these old French posters advertising the drink to be quite interesting and beautiful. So here they are.
