Lesson 4

Preparation

Smoking

The people of pre-Columbian America were
the first users of tobacco.

They cultivated the plant and smoked it in pipes
for medicinal and ceremonial purposes.

However, too much of a good thing is bad.
Studies have shown that non-smokers live

longer than smokers do.

They have clearer lungs and are less vulnerable
to lung cancer.
