absinthe and it is supposed to be the strongest stuff they can legally make. Absinthe is illegal to sell but legal to posess in the U.S. It's kind of a catch twenty two but you can order it without much fear of anybody prosectuing you.
As for my experience with it, I was not all that impressed. I had a friend bring me a bottle of the real deal back from Spain over the summer. The preperation is pretty cool and it tastes good but I didn't notice any abnormal effects except you seem to stay a little more clear headed even if you get a little drunk. The standard prep is to 1. pour a shot or three of it into a tall glass. Have some ice water on standby. 2. take a spoon of sugar and dip it in Absinthe leaving the Absinthe soaked sugar on the spoon. 3. Light the sugar on fire and as it carmalizes pour it into the Absinthe. 4. Typically, as you pour, the absinthe in the glass will also catch on fire. 5. Pour the ice cold water into the Absinthe to extinguish the flames and dilute the alcohol. 6. Drink up.
All in all it's cool for something a little different but don't expect anything mindblowing
