Effect of cigaratte smoking on the sense of smell

In Biology class we are starting with some new projects. The teacher made groups and each of them has to present a different topic. I’m working with Alexis Stankiewich and Bautista Buljevich with topic number 7: Effect of cigaratte smoking on the sense of smell. Today 2/8 we are doing reasearch on this topic so we can start preparing our presentation.
