Analysis of Pernicious Weed!

The pipe, with solemn interposing puff,
Makes half a sentence at a time enough;
The dozing sages drop the drowsy strain,
Then pause and puff, and speak, and pause again.
Such often, like the tube they so admire,
Important triflers! have more smoke than fire.
Pernicious weed! whose scent the fair annoys,
Unfriendly to society's chief joys,
Thy worst effect is banishing for hours
The sex whose presence civilizes ours.
