19 Jul The effect of smoking cannabis and smoking cannabis and tobacco combined on forced vital capacity and forced expiratory volume in one second of 18-year-old males

Adolescents represent a considerable percentage of cannabis users, but the effect of smoking on their pulmonary function has not yet been investigated. Therefore, I decided to compare forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) of cannabis smokers with combined cannabis and tobacco smokers and control group of non-smokers, all participants being 18-year-old males. In previous studies, several mechanisms were proposed to explain inconsistent higher values of FVC and FEV1 in long-term cannabis smokers while smoking tobacco was repeatedly found to decrease both parameters. However, results of this study showed higher FEV1 in the group of cannabis smokers while differences in FVC were statistically insignificant, presumably due to lower exposure to substances.
