The use of electronic cigarettes, commonly referred to as e-cigarettes or vapes, has increased exponentially in recent years despite the lack of research into potentially negative physiological effects. The rise in e-cigarette use is likely due to the overwhelming evidence regarding the addictive properties of nicotine and the damage caused by traditional tobacco cigarettes. Most e-cigarettes, however, still contain nicotine and are associated with a rise in nicotine-related intoxications (Belkoniene et al., 2019). There are nicotine-free e-cigarette options, which are gaining popularity, but it is unknown if they carry similar or other negative physiological effects. Studies involving e-cigarettes containing nicotine show that inhalation increases whole-body metabolic rate, yet studies including nicotine-free e-cigarettes are currently lacking (Olfert et al., 2018). This project intended to investigate any differences in maximal metabolic rate (MMR) following an acute exposure period to water with dissolved e-cigarette vapors; with the hypothesis that both nicotine and nicotine-free vapor will increase MMR. The Louisiana crayfish, Procambrus clarkii, was the organism studied due to availability and their low maintenance requirement. E-cigarette vapor did not have a statistically significant effect on MMR between treatment groups or with the control group.
