A new Purdue University exhibit is shining a spotlight on the positive side of the psychedelic drugs that got a bad reputation in the 1960s.
The exhibit running through Aug. 13 at the campus' Special Collections Research Center is the creation of Purdue pharmacology professor David E. Nichols, who's studied how psychoactive drugs can alter human consciousness.
He says the "Unlocking the Doors of Perception" exhibit focuses on legitimate research into the role those drugs can play in medicine and healing.
Nichols hopes to make Purdue a repository for important documents on psychoactive drugs.
The exhibit includes books autographed by Albert Hofman, the Swiss chemist who discovered the hallucinogenic drug LSD that helped fuel the psychedelic culture of the 1960s.
