“My first sensations under the new drug were similar to those induced by a strong dose of Cannabis indica. There was the same protraction of the time-sense, by which mere minutes were stretched out into ages; and the same spatial expansion, by which my laboratory walls appeared to recede to an immense distance, and my own body, as well as the familiar objects about me, extended themselves to prodigious height and length. The legs of my chair were tall as the famed sequoias. My hand and arm, reaching up to make sure that the graph was correctly adjusted on my forehead over the pineal gland, seemed to scale a gulf like that of some profound canyon. A carboy loomed like a giant monument.

“I gazed on a medley of strange-angled forms that might have materialized from a geometrician's nightmare.”

Clark Ashton Smith, 1933
