From Chapter 2:
The properly accomplished gallant not only professed to be curiously learned in pipes and tobacco, but his knowledge of prices and their fluctuations, of the apothecaries' and other shops where the herb was sold, and of the latest and most fashionable ways of inhaling and exhaling the smoke, was, like Mr. Weller's knowledge of London, "extensive and peculiar." It was knowledge of this kind that gained for a gallant reputation and respect by no means to be acquired by mere scholarship and learning.

From Chapter 6:
The local authorities in our eastern counties seem to have had some curious ideas of their own as to where tobacco should or should not be smoked. In a previous chapter we have seen that at Norwich, ale-house keepers were fined for permitting smoking in their houses. At Methwold, Suffolk, the folk improved upon this. The court-books of the manor of Methwold contain the following entry made at a court held on October 4, 1695: "We agree that any person that is taken smoakeinge tobacco in the street shall forfitt one shillinge for every time so taken, and itt shall be lawfull for the petty constabbles to distrane for the same for to be putt to the uses abovesaid [i.e. "to the use of the town"]. Wee present Nicholas Baker for smoakeinge in the street, and doe amerce him 1s." The same rule is repeated at courts held in the years 1696 and 1699, but no other fine is mentioned at any subsequent courts. The good folk at Methwold may have been adepts at petty tyranny, but such an absurd regulation must soon have become a dead letter. While we are in the eastern counties we may note that in 1694 there died at Ely an apothecary named Henry Crofts, who owned, among some other unusual items in his inventory, casks of brandy and tobacco, which shows that even at that date, when regular tobacconists' shops for the sale of tobacco had long been common, the old business connexion between apothecaries and tobacco still occasionally existed.

From Chapter 10:
The flight of fancy in the last sentence has hardly yet been fulfilled; but I saw, many years ago, a distinguished man of letters, the late Mr. Francis Turner Palgrave, of "Golden Treasury" fame, who was an inveterate smoker, sitting on one of the cane benches by the door of the Athenæum Club, smoking a short clay pipe.

Thackeray does not appear to have realized that tobacco was not invading England for the first, but for the second time, nor did he foresee that the ladies, to whom he addressed his impassioned defence of smoking, would not only submit to the conqueror but would themselves be found among his joyous devotees.

From Chapter 7:
There is no mention of Parson Trulliber's pipe, but that pig-breeder and lover can hardly have been a non-smoker. Both the other clerical characters who appear in the book, the Roman Catholic priest who makes an equivocal appearance in the eighth chapter of the third book, and Parson Barnabas, who thinks that his own sermons are at least equal to Tillotson's, smoke their pipes. The other smokers in "Joseph Andrews" are the surgeon and the exciseman who, early in the story, are found sitting in the inn kitchen with Parson Barnabas, "smoking their pipes over some syderand"—the mysterious "cup" being a mixture of cider and something spirituous—and Joseph's father, old Gaffer Andrews, who appears at the end of the story, and complains bitterly that he wants his pipe, not having had a whiff that morning.
