ELI5: How did the acceptance and promotion of drug and alcohol use (e.g., Marijuana, Percocet, codeine, Xanax, Hennessy, Molly) become so common in pop culture, notably the music industry?

It always has been, pretty much. Different eras had different addictions, of course, and alcohol is the most common in older times.

Removing the alcohol, since that's legal, you still get references to drug use as early as the 1930s, with artists like Herb Morland and Cab Calloway. In the 70s, there was a growth of hard drug references in songs, like "Lucy in the Sky with Diamonds" (LSD).
