It is definitely not a modern phenomenon - think of the WW1 hampers of comforts from Harrods to send to the front, which contained hard drugs and the equipment to use them. Think of "Confessions of an Opium Eater" and the dependence of so many Victorian women on laudanum, that soother of pain and anguish. That was even given to babies who were teething and fractious. I wonder what that did to the ease with which they later became addicts!
Laudamun was a tincture of 90% alcohol and 10% opium. "It was first used by the ancient Greeks, and in the 19th century mostly used as painkiller, sleeping pill, or tranquilizer. It was cheaper then poppy oil and could be drank like you’d drink scotch. It took a while for the Victorian to figure out the negative side effect, only in 1919 the production and export of opium was prohibited, and in 1928 a law was passed that prohibited use."

Users included Lord Byron, Samuel Taylor Coleridge, Percy Bysshe Shelley, John Keats, Lewis Carroll, Charles Dickens, Edgar Allan Poe, all examples of creative "artistic" people, plus repressed housewives trapped in a cycle of useless inactivity in golden cages, plus the denizens of city rookeries with no hope of better lives. Nothing new there, then.
