J. Hector St John de Crevecoeur, Letters from an American Farmer. UK: Davies and Davis, 1782—
A singular custom prevails here [on Nantucket Island] among the women, at which I was greatly surprised, and am really at a loss to account for the original cause that has introduced in this primitive society so remarkable a fashion, or so extraordinary a want. They have adopted these many years the Asiastic custom of taking a dose of opium every morning; and so deeply rooted is it, that they would be at a loss how to live without this indulgence; they would rather be derprived of any necessary than forego their favorite luxury. This is much more prevailing among the women than the men…though the sheriff…has for many years submitted to this custom. He takes three grains of it every day after breakfast, without the effects of which, he often told me, he was not able to transact any business.
