activity of science on tobacco consumption and cancer with images​

Answer 1

Answer:

Spit tobacco, also known as chewing tobacco and snuff, are forms of tobacco that are put between the cheek and gum. Chewing tobacco can be in the form of leaf tobacco (which is packaged in pouches), or plug tobacco (which are packaged in "brick" form). Snuff is a powdered form of tobacco, usually sold in cans. The nicotine is released from the tobacco as the user "chews."

Although chewing tobacco and snuff are considered smokeless tobacco products, harmful chemicals including nicotine are ingested. More than 28 cancer-causing chemicals have been found in smokeless tobacco.

Chewing tobacco and snuff can cause cancer in the cheek, gums, and lips. Just as with a pipe, cancer often occurs where the tobacco is held in the mouth. Cancer caused by smokeless tobacco often begins as leukoplakia, with a whitish patch that develops inside the mouth or throat. Or the cancer may erythroplakia. With this condition, a red, raised patch develops inside the mouth. It's also linked to esophageal and pancreatic cancers
