One of the CIA’s “New Ghetto Drugs for ’98” collection, Brainscratch is a cheap hallucinogen that comes in the form of a liquid taken by dropping it into the eyes.
The result of taking Brainscratch is terrifying hallucinations. Test subjects reported loss of identity and feelings of total dislocation from human world, and its effects can last anywhere from ten years to the rest of the life of the user. Pretty good value for the cost of only two American dollars per hit.
