From Chapter 3:
Some of the apothecaries whose shops were in most repute for the quality of the tobacco kept, took pupils and taught them the "slights," as tricks with the pipe were called. These included exhaling the smoke in little globes, rings and so forth.

He comes up every term to learn to take tobacco and see new motions." Sogliardo was accustomed to hire a private room to practise in. The fashionable way was to expel the smoke through the nose. In a play by Field of 1618, a foolish nobleman is asked by some boon companions in a tavern: "Will your lordship take any tobacco?" when another sneers, "'Sheart! he cannot put it through his nose!" His lordship was apparently not well versed in the "slights."
