From Chapter 15:
After the suppression of the Jacobite uprising of 1745, the English Government made war on Scottish nationality, and among other measures the wearing of the highland dress was forbidden by Parliament. On this occasion the following paragraph appeared in the newspapers of the time: "We hear that the dapper wooden Highlanders, who guard so heroically the doors of snuff-shops, intend to petition the Legislature, in order that they may be excused from complying with the Act of Parliament with regard to their change of dress: alledging that they have ever been faithful subjects to his Majesty, having constantly supplied his Guards with a pinch out of their Mulls when they marched by them, and so far from engaging in any Rebellion, that they have never entertained a rebellious thought; whence they humbly hope that they shall not be put to the expense of buying new cloaths." This is not a very humorous production, but at least it bears witness to the common occurrence in 1746 of the highlander's figure at the shops of snuff and tobacco-sellers.

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 4:
Some of the Puritan colonists in America took a strong line on the subject. Under the famous "Blue Laws" of 1650 it was ordered by the General Court of Connecticut that no one under twenty-one was to smoke—"nor any other that hath not already accustomed himself to the use thereof." And no smoker could enjoy his pipe unless he obtained a doctor's certificate that tobacco would be "usefull for him, and allso that he hath received a lycense from the Courte for the same." But the unhappy smoker having passed the doctor and obtained his licence was still harassed by restrictions, for it was ordered that no man within the colony, after the publication of the order, should take any tobacco publicly "in the streett, highwayes, or any barn-yardes, or uppon training dayes, in any open places, under the penalty of six-pence for each offence against this order." The ingenuities of petty tyranny are ineffable. It is said that these "Blue Laws" are not authentic; but if they are not literally true, they are certainly well invented, for most of them can be paralleled and illustrated by laws and regulations of undoubted authenticity.

From Chapter 3:
Penalties for "offences" of this fanciful kind were not common in England; but in Puritan New England they were abundant. In the early days of the American Colonies the use of the "creature called Tobacko" was by no means encouraged. In Connecticut a man was permitted by the law to smoke once if he went on a journey of ten miles, but not more than once a day and by no means in another man's house. It could hardly have been difficult to evade so absurd a regulation as this.
