This short, silent comedy is a bit of classic weirdness from 1916. Apparently it's quite well known, even considered a cult classic. But I hadn't heard of it before, so perhaps it'll be new to you too. Wikipedia offers this description:
In this unusually broad comedy for [Douglas] Fairbanks, the acrobatic leading man plays "Coke Ennyday," a cocaine-shooting detective parody of Sherlock Holmes, given to injecting himself from a bandolier of syringes worn across his chest, and liberally helping himself to the contents of a hatbox-sized round container of white powder labeled "COCAINE" on his desk.
Fairbanks's character otherwise lampoons Sherlock Holmes with checkered detective hat, clothes and even car, along with the aforementioned propensity for injecting cocaine whenever he feels momentarily down, then laughing with delight. A device used for observing visitors, which is referred to in the title cards as his "scientific periscope", bears a close resemblance to a modern closed-circuit television. What is apparently a clock face has "EATS, DRINKS, SLEEPS, and DOPE" instead of numbers.
The film displays a lighthearted and comic attitude toward Coke Ennyday's use of cocaine and laudanum, while he catches a gang of drug smugglers, he does so after consuming most of their opium. One of the actresses appearing, Alma Rubens, later became addicted to morphine and died young.
