Abstract :
Rapidly increasing in popularity, e-cigarettes have proved to be detrimental to human health. Appealing most to youth aged 12-17, e-cigarettes have been the cause of thousands of cases of lung-related illnesses around the world. Adequately addressing this situation requires a complete understanding of the effects of e-cigarettes. This study examines how secondhand and thirdhand exposure to e-cigarette vapor affects youth and adult populations via the model organism Drosophila melanogaster. This experimental study analyzed groups of 6-10 flies that were exposed to e-cigarette vapor once a day for 8 consecutive days. The experiment analyzed the activity and behavior of the flies and showed that both secondhand and thirdhand exposure to e-cig vapor affects both youth and adult populations negatively through the assessments of geotaxis and olfactory perception. Data from the flies exposed to secondhand and thirdhand vapor were compared to data from flies not exposed to vapor. The flies exhibited both a lower average climb height and reduced ability to smell fruit placed in the environment. Additionally, it was observed that youth were affected more severely than adults, and that thirdhand exposure was almost as harmful as secondhand exposure. The different types of exposure presented to populations in different stages of life prove to have a visible effect on the perceptionary strength of the flies, which may translate to effects experienced by humans undergoing the same types of exposure.
