My project explores the long-term effects of aerosolized propylene glycol and vegetable glycerin, two of the main non-nicotine ingredients in e-cigarettes, by looking at mutations in Drosophila Melanogaster, also known as fruit flies. I found a statistically significant decrease in size, number of offspring, and mutations in wing structure, as well as changes in behavior. The finding of my experiment is important in the real world because it is highly probable that exposure to aerosolized VG and PG is dangerous and a cause for major concern. My experiment also supports the idea that this aerosol can not only have effects within a single generation, but also in future generations.
