Arguably the anthem of the drugs and rock era was The Jefferson Airplane’s “White Rabbit”: Lyrics include:

“One pill makes you larger and one pill makes you small/And the ones that mother gives you don’t do anything at all/Go ask Alice, when she’s ten feet tall/When the men on the chess board get up and tell you where to go/You just had some kind of mushroom and your mind is moving low” (Szatmary, 1987, p. 122)

The song ends with an entreaty to “FEED YOUR HEAD, FEED YOUR HEAD.” https://www.youtube.com/watch?v=XR8LFNUr3vw
