As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air finally reaches and enters the alveoli air sacs.When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.

As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.

I believe this is a good question. Cause there are many people who are experiencing this. I believe that you would want to go slowly with the topic and not too fast cause you might get the person mad. Start off slow and try to understand why they smoke and why they chose to go with the group of people. Many people smoke due to stress, problems, etc. It makes them better knowing they can have drugs in their system. Although thats not the answer. Try to seek help for your friend or try to understand him and show him how you care and how his choices are affecting you
