From Chapter 2:
In the afternoon the gallant might attend what Dekker calls a "Tobacco-ordinary," by which may possibly have been meant a smoking-club, or, more probably, the gathering after dinner at one of the many ordinaries in the neighbourhood of St. Paul's Cathedral of "tobacconists," as smokers were then called, to discuss the merits of their respective pipes, and of the various kinds of tobacco—"whether your Cane or your Pudding be sweetest."

Of course he often bragged, like Julio in Day's "Law Trickes": "Tobacco? the best in Europe, 't cost me ten Crownes an ounce, by this vapour."

From Chapter 8:
All's well that ends well; but one cannot help wondering what kind of tobacco it was that the Birmingham tradesman used, a half pipeful of which had such a deadly effect—but perhaps the effect was due to the salt, not to the tobacco.
In the year after that which witnessed Coleridge's adventure, i.e. in 1796, a tobacco-box with a history was the subject of a legal decision. This box, made of common horn and small enough to be carried in the pocket, was bought for fourpence by an overseer of the poor in the time of Queen Anne, and was presented by him in 1713 to the Society of Past Overseers of the parish of St. Margaret, Westminster. In 1720 the Society, in memory of the donor, ornamented the lid with a silver rim; and at intervals thereafter additions were made to an extraordinary extent to the box and its casings. Hogarth engraved within the lid in 1746 a bust of the victor of Culloden. Gradually the horn box was enshrined within one case after another—usually silver lined with velvet—each case bearing inscribed plates commemorating persons or events. A Past Overseer who detained the box in 1793 had to give it back after three years of litigation. A case of octagon shape records the triumph of Justice, and Lord Chancellor Loughborough pronouncing his decree for the restitution of the box on March 5, 1796. In later days many and various additions have been made to the many coverings of the box, recording public events of interest.
