Historical & Cultural Background
Ancient Origins
Nicotine use dates back over 2,000 years. Indigenous peoples of the Americas used tobacco in:

It was not recreational addiction—it was symbolic and controlled.

This layered history explains why nicotine carries both ritual value and health controversy.
