Sorry if this topic has already been dealt with - I couldn't find it mentioned below, but I have limited patience for slow scrolling.
Does this infamous concoction genuinely have any hallucinogenic qualities, or are its effects psychosomatic and caused by its fearsome reputation? Does it make you insane, blind, or both? There are now various brands doing the rounds in the UK, mostly originating in Czech Republic... are any of these particularly recommended? Is there a reliable pool of information on the web?
All information gladly received as I am shortly to enter some shady form of decadant poetry / absinthe-consumption death-match.
