Absinthe was outlawed in a number of countries earlier in the last century. It was believed to drive drive people crazy and encourage violent criminal behaviour. It was also very popular--the ban was supported by vintners and other spirit makers.
It has come back into fashion over the last few years. I know you can buy it in France again, though getting absinthe considered "authentic" is another story.
And Barsoomcore, you did go for the "hair of the dog", can you get away with that at work?
