It is just a random thought I had while smoking my cigarette. Did Newton smoke tobacco? Some sites claim that he "smoked immoderately", while others are of the opinion that he never touched a pipe and upon being asked why not, he replied:

“I am unwilling to make to myself any necessities."

I am also attaching an image which a website claims to be of his pipe.

Newton's pipe

I am willing to accept any views on this topic.
