Lung Health Variables

Throughout our lives we are told that smoking is bad for us, and smoking marijuana is worse. We are told that if we smoke we will not be good athletes. This experiment was designed to test how extensively smoking tobacco, and smoking marijuana negatively affect a person’s lungs and how extensively exercise positively affects a person’s lungs.

At first there was no apparent way to test people’s lungs, after some Internet research there was found that there is a device called a spirometry that will test a person’s lung volume and lungpower. After acquiring a spirometry, test subjects took a survey that asked them about their experiences involving smoking tobacco, marijuana, and exercising. The data was then collected and graphed.


With all of the data shown it became very apparent that smoking was not beneficial weather it was tobacco or marijuana. Although they were both harmful, people who smoked marijuana seemed to have better lung health than those who smoke tobacco. Paramount to the negatives of both was the positives of both. The spirometry measures Peak Flow (Lung Power) and FEV1 (Lung Volume). Smoking Tobacco Was particularly harmful to the FEV1. Exercise was even more beneficial to the Peak Flow.

This is particularly interesting because of how much marijuana is said to be much worse for you than tobacco, this research suggests differently. Because of how strongly this experiment suggests that smoking is harmful, it is highly ill advisable. Although smoking is very harmful, so is inactivity, and it is also something that should be avoided.
