About to start my first Yom Kippur fast, with snuff to assist and strengthen me, as is permitted.
"In spite of some objections, snuff-taking was permitted at any time—Sabbaths, holy days, fast-days, and Yom Kippur ("Leḳeṭ ha-Ḳemaḥ," p. 51b, Amsterdam, 1707). Jacob Ḥaziz (1620-74) quotes a responsum of Isaiah Pinto permitting the use of snuff on Sabbaths, even though it cures catarrh; for everybody, even healthy people, snuff, and it can not therefore be considered a drug ("Halakot Ḳeṭannot," No. 101)."
A good and meaningful fast for my fellow Jewish snuff-takers.
