Ludlow’s writings crop up in a couple of places in pre-marijuana-prohibition 20th century America. The occultist Aleister Crowley found "The Hasheesh Eater" to be “tainted by admiration of de Quincey and the sentimentalists” but admired Ludlow’s “wonderful introspection” and printed significant excerpts from the book in his journal "The Equinox". Using the pseudonym Oliver Haddo, Crowley also wrote at length about his own cannabis experiences, comparing and contrasting them to those of Ludlow. He “was struck by the circumstance that , obviously ignorant of Vedantist and Yogic doctrines, yet approximately expressed them, though in a degraded and distorted form.”
