Purple Haze is a expression used to describe a specific brightly purple strain of cannabis. It was initially used to describe a type of LSD sold on purple blotter paper.

Purple Haze is actually a glorified term that was adapted from the Jimi Hendrix song, which most believe was created about the "brand" of super potent LSD created by Owsley Stanley.  Stanley called this batch of LSD "Monterey Purple" in anticipation of the pending Monterey Pop Festival at which Hendrix reportedly consumed the drug prior to going onstage. One reader recalls that according to a Rolling Stone Magazine article about the Monterey Pop Festival (published circa late 1980's), much of the festival audience was also high on Monterey Purple acid. The same article reported that Owsley had his people stationed at the entry gates holding huge jars filled with the purple tabs, inviting festival-goers to take handfuls. In a High Times Magazine article by Bruce Eisner from January 1977, Eisner reports to have actually interviewed Tim Scully, one of the men involved in creating the LSD. According to Scully, Augustus Owsley Stanley III, began to manufacture LSD in Los Angeles in 1965. It was legal then. Owsley's LSD came in 270 microgram tablets of purple (Purple Haze) and white (White Lightning). LSD became illegal in 1966 and Owsley was arrested in December of 1967.
