Having inhaled them, you initiate the process of change in the lung tissue right away.

At first, your organism handles the situation successfully and manages to make up for the harm inflicted. However, being constantly exposed to the smoke results in normal cells being damaged to a great degree. As time goes by, these severely impaired cells start functioning abnormally thus leading to cancer.
