The things you learn when researching a novel never cease to amaze!!
In 1624, Maffeo Barbarini (1568-1644) aka Pope Urban VIII (1623-1644) issued a papal bull that ordered a worldwide ban on the smoking and sniffing of tobacco on pain of excommunication.
For health reasons?
Because he believed it led to sneezing and that sneezing too closely resembled sexual ecstasy.
Though I think Mikhail I Fyodorovich Romanov aka Tsar Michael of Russia (1596-1645) had a much more frightening way to enforce the ban on smoking that he invoked in 1634…
…A first offence meant a whipping, a slit nose and an exile to Siberia.
And those caught a second time faced execution.
