Excuse me, but nope. It was banned in the beginning of the 19th century as a result of a moral panic because it was a rather cheaply available drink in France at the time. For the tujone in it to have any effect, you'd have to consume so much that you'd get alcohol poisoning first. And modern double-distilled absinthe, sold in liquor stores everywhere, is "real absinthe" - or even better, because the version poor Frenchmen drank was made for cheap and without much care for quality. But the problems it caused were just shitty alcohol problems, anyway.
Wikipedia will tell you all this and more in the span of a few pages. I can link you several studies about absinthe toxicity wich conclude it is about zero.
Absinthe has often been portrayed as a dangerously addictive psychoactive drug and hallucinogen.[8] The chemical compound thujone, although present in the spirit in only trace amounts, was blamed for its alleged harmful effects. By 1915, absinthe had been banned in the United States and in much of Europe, including France, the Netherlands, Belgium, Switzerland and Austria-Hungary. Although absinthe was vilified, it has not been demonstrated to be any more dangerous than ordinary spirits. Recent studies have shown that absinthe's psychoactive properties (apart from that of the alcohol) have been exaggerated.
Tl;dr: absinthe was hip and edgy drink, so edgy it got banned. Actually not edgy at all.
E: ninja'd. Actually, the array of effects it was claimed to cause in the 19th century was so broad that they were bound to hit a few times, especially since a lot of them are very similar to the effects of, you know, ethanol. But whatever, I may be wrong. Anyway, the consumption of one small glass of absinthe, real or not, will not cause you to flip your shit.
