I recently aquired some Absinthe from England; it came via US mail in a package marked "herbal extracts." It was french and a clone of the classic Pernod recipe called Edward, it was awsome (stillis since I got two bottles), but I really think the buzz came from it being soooo tasty and going down smoothe and fast and being 72% alcohol! Not the wormwood. There are claims at Oxygene.com (good absinthe site) about those affects but even those tasters say that the thujone affects are subtle and gone after 25 minutes. All I know was that after a couple I was pretty tipsy - giddy would be a better term - likely from rapid alcohol ingestion.
If anyone tries this, it's a great drink, don't waste money on the fancy drippers, just add about a teaspoon of sugar, a couple ice cubes, and ice water - oula, le fee vert - the green fairy.
by the way - avoid any absinthe from Checoslovakia, it's way expensive and not the real thing, more like mouthwash, I fell victim to one bottle that I now use in airlocks - my wife hates the smell but I kinda like it, a mediciny sanitary smell like it's doin it's job (not like the French variety which is exquisite)
