Where does kick the habit originate?

"Kick the habit" originally referred to quitting the habit of smoking opium, which was widespread in the 19th century, especially in China. The term "kick" refers to the physical symptoms of withdrawal from opium, including muscle spasms and convulsions. The phrase "kick the habit" likely arose as a way to describe the effort and struggle required to overcome opium addiction. Over time, the phrase became more generalized and is now used to refer to breaking any negative or unwanted habit.
