The founder of the Hare Krishna movement, A. C. Bhaktivedanta Swami Prabhupada (1896-1977) was a snuff-taker:
"Regarding taking snuff, I myself take it sometimes at night because I am working at night on my books, and sometimes I become dizzy. But it is not for you to take. You should not imitate this, neither you work like me at night.
" (letter, LA, 9 January 1974).
"We arrived in Toronto at 6:30 P.M. (June 16 1976) and had our most disagreeable encounter with customs officials yet. I accompanied Srila Prabhupada, who carried his soft, red vinyl hand bag, while Pusta Krsna Maharaja remained behind to bring the luggage through. On the other side of a glass wall next to the customs counter a large number of devotees, many from the Indian community, expectantly gathered. As soon they saw Srila Prabhupada they cheered, “Jaya Prabhupada! Haribol!” There were two customs officers. One of them, tall, with an unpleasant demeanor and a slight sneer on his face, asked Prabhupada to open his bag. Then, slowly, with exaggerated attention, he searched every single item. Before leaving Bombay I had sealed several new tins of snuff with hot wax. Prabhupada uses it to gain relief from high blood pressure. The official insisted on breaking each seal to check inside"
"Prabhupada was being given tobacco snuff on a daily basis. I know this also because Manihar brought some back and used to snort it regularly. He even let us try it and told us it was ok because Prabhupada used it. He also reminded us not to talk about it. (When our class was initiated we even bought him a snuff container as part of our Guru dakshina.). It is not only addicting but also not known to people in general that Prabhupada was regularly given tobacco snuff. The fact that it is never talked about makes me suspicious. If it was for his health than why hide it.
My guess would be that he had picked up the habit at the Scottish Church College in Calcutta where he was educated. Scottish Presbyterian teachers (and pupils) would surely not have been averse to a pinch every so often, while Vaishnava Hindus would have been horrified. I would also guess that Hare Krishna is the only example of a religious movement founded by a snuff-taker.
