7-Up first arrived in 1929 with the less-catchy name of “Bib Label Lithiated Lemon-Lime Soda.” A mouthful, but note the third word; the drink contained the mood enhancer lithium until it was federally banned from beer and soft drinks in 1948. Coincidentally, the drink appeared just weeks before the The Great Depression began in the US, when most people needed all the mood lightener they could get.
Heroin was developed by drug giant Bayer in 1895 as a painkiller and cough suppressant, promoted as safer than morphine, and was even recommended for children. The name derives from “heroisch,” German for “heroic,” but the company quit selling the syrup 15 years later when its addictive properties had become obvious.
From 1886 until 1903, Coca-Cola did indeed contain real cocaine, and the “Cola” part is from the kola nut, the extract of which supplied caffeine in the first recipe. The original drink was produced as a type of faux wine in response to a short-lived 1886 alcohol ban in Atlanta, where the company is still headquartered.
