unless the photo was taken in Europe (I didn't read the whole thread) there isn't any narcotics in commercialized absinth, in North America at least. You won't get a buzz, but I heard the "drunk effect" is a bit weirder than being drunk on, say, beers. Like getting drunk on wine feels different than getting drunk on beers.
edit: And pretty much all absinth has a concentration of 70% of alcool... at least that's how it was when I was in Edmonton.......... you need to mix it with water and other juices if you want to drink it. Alone it tastes like crap.
