Parker Laboratories, Inc. , doing business as Gilmar Laboratories, Inc. of Newark , N.J. Filed a trademark application on Aug.18, 1967, for both "POT" and "LSD", words to be used a names for colognes. The trademarks were granted in 1968.
Curiously enough, a rival company also applied for the "LSD" name in 1967, they were granted the trademark as well.
All three of these fragrances have been discontinued since the 1960s. I have no evidence that they were sold beyond 1968. They did not have narcotic ingredients inside, they were just colognes made by companies capitalizing on the popular drugs of the period. Today, they are considered extremely rare collectibles of the psychedelic era.
