From Chapter 3:
Another tract which may be classed with Venner's "Treatise" was the "Nepenthes or the Vertues of tobacco," by Dr. William Barclay, which was published at Edinburgh in 1614. This is sometimes referred to and quoted, as by Fairholt, as if it were a whole-hearted defence of tobacco-taking. But Barclay enlarges mainly on the medicinal virtues of the herb. "If Tabacco," he says, "were used physically and with discretion there were no medicament in the worlde comparable to it"; and again: "In Tabacco there is nothing which is not medicine, the root, the stalke, the leaves, the seeds, the smoake, the ashes." The doctor gives sundry directions for administering tobacco—"to be used in infusion, in decoction, in substance, in smoke, in salt." But Barclay clearly does not sympathize with its indiscriminate use for pleasure. "As concerning the smoke," he says, "it may be taken more frequently, and for the said effects, but always fasting, and with emptie stomack, not as the English abusers do, which make a smoke-boxe of their skull, more fit to be carried under his arme that selleth at Paris dunoir a noircir to blacke mens shooes then to carie the braine of him that can not walke, can not ryde except the Tabacco Pype be in his mouth." He goes on to say that he was once in company with an English merchant in Normandy—"betweene Rowen and New-haven"—who was a merry fellow, but was constantly wanting a coal to kindle his tobacco. "The Frenchman wondered and I laughed at his intemperancie."

From Chapter 5:
The French traveller, Sorbière, who visited London in 1663, declared that the English were naturally lazy and spent half their time in taking tobacco. They smoked after meals, he observed, and conversed for a long time. "There is scarce a day passes," he wrote, "but a Tradesman goes to the Ale-house or Tavern to smoke with some of his Friends, and therefore Public Houses are numerous here, and Business goes on but slowly in the Shops"; but, curiously enough, he makes no mention of coffee-houses. A little later they were too common and too much frequented to be overlooked. An English writer on thrift in 1676 said that it was customary for a "mechanic tradesman" to go to the coffee-house or ale-house in the morning to drink his morning's draught, and there he would spend twopence and consume an hour in smoking and talking, spending several hours of the evening in similar fashion.
