Mickey Finn (drugs)
In slang, a Mickey Finn (or simply Mickey) is a drink laced with a drug (especially chloral hydrate) given to someone without their knowledge in order to incapacitate them. Serving someone a Mickey is most commonly referred to as slipping one a mickey, sometimes spelled "slipping one a mickie".
History of term 
Michael "Mickey" Finn 
The Mickey Finn is most likely named for the manager and bartender of a Chicago establishment, the Lone Star Saloon and Palm Garden Restaurant, which operated from 1896 to 1903 in the city's South Loop neighborhood on South State Street. In December 1903, several Chicago newspapers document that a Michael "Mickey" Finn managed the Lone Star Saloon and was accused of using knockout drops to incapacitate and rob some of his customers. Moreover, the first known written example (according to the Oxford English Dictionary) of the use of the term Mickey Finn is in 1915, twelve years after his trial, lending credence to this theory of the origination of the phrase.
The first popular account of Mickey Finn was given by Herbert Asbury in his 1940 book Gem of the Prairie: An Informal History of the Chicago Underworld. His cited sources are Chicago newspapers and the 1903 court testimony of Lone Star prostitute "Gold Tooth" Mary Thornton. Before his days as a saloon proprietor, Mickey Finn was known as a pickpocket and thief who often preyed on drunken bar patrons. The act of serving a Mickey Finn Special was a coordinated robbery orchestrated by Finn. First, Finn or one of his employees, which included "house girls", would slip a drug (chloral hydrate) in the unsuspecting patron's drink. The incapacitated patron would be escorted or carried into a back room by one of Finn's associates who would then rob the victim and dump him in an alley. Upon awaking the next morning in a nearby alley, the victim would remember little or nothing of what had happened. Finn's saloon was ordered closed on December 16, 1903.
In 1918, Mickey Finn was apparently arrested again, this time for running an illegal bar in South Chicago.
Chicago restaurant poisonings 
On June 22, 1918, four people were arrested and over one hundred waiters taken into custody over the apparent widespread practice of poisoning by waiters in Chicago. Guests who tipped poorly were given "Mickey Finn powder" in their food or drinks. Chemical analysis showed that it contained antimony and potassium tartrate. Antimony is known to cause headaches, dizziness, depression, and vomiting and can be lethal in large quantities. W. Stuart Wood and his wife were arrested for manufacturing the powder, and two bartenders were arrested for selling the powder at the bar at the waiters' union headquarters. Wood sold packets of the powder for 20 cents  and referred to it as "Mickey Finn Powder" in a letter to union bartender John Millian. A follow-up article mentions the pursuit of a man named Jean Crones who was believed to be responsible for poisoning over 100 people at a Chicago University Club banquet at which three people died.
Tracing usage of the phrase "Mickey Finn" 
The Oxford English Dictionary gives a chronology of the term, starting in 1915. The 1915 citation is from a photograph of a saloon in the December 26 edition of the Los Angeles Examiner. In the photograph is a sign that reads "Try a Michael Finn cocktail". The first listed reference as a knock-out drop in the OED, "Wish I had a drink and a Mike Finn for him", is from a March 11, 1924 article in the New York Evening Journal. A description of a Mickey Finn is given in the January 18, 1927 issue of the Bismarck Tribune, "a Mickey Finn is an up-to-date variant on the knock-out drops of pre-war days". In the September 3, 1927 issue of the Chicago Daily Tribune, the phrase appears in an article on the use of ethylene for artificial ripening of fruit, "Applied to a human, ethylene is an anaesthetic as the old-time Mickey Finn in a lumber-jack saloon". The phrase also appears in the January 13, 1928, issue of Variety, "Mickeyfinning isn't describable, but it's easily worked, leaving its victims miserable. The work is accomplished mainly by bartenders... Mickeyfinning has been behind some of the nite club liquor trouble, with the victims so sore they don't care what their revenge might bring".

- The saloon's exact location is usually said to be the on west side of South State Street, just north of Congress Parkway. The entire west side of South State Street, between Congress and Van Buren, is now occupied by Chicago Public Library's Central Library (also known as the Harold Washington Library at 400 South State Street). The December 16–17, 1903, Chicago Daily Tribune articles give the address as 527 State Street (Corner of State and Harmon Court), however, which is now the 1100 block of South State Street. The 500 block of South State Street now is between Congress Street and Harrison Street, which may be the reason for the confusion of the saloon's location. For the 1903 Chicago street names and numbering refer to "New map of Chicago showing street car lines in colors and street numbers in even hundreds", Chicago : Rufus Blanchard, 1897.
- The area on State Street centered between Van Buren Street (to the North) to Harrison Street (to the South) was known as "Whiskey Row" from the late 1880s to the early 1910s. Just south of Harrison Street was a block known as "Hell's Half Mile". The area of State Street, south of Harrison was also known as "Satan's Mile".

The work was done in two little rooms adjoining the palm garden in back of the saloon".
