A Mixed Methods Pilot Study on the Short-Term Physiological Effects of Vaping and Attitudes Regarding Its Use and Health Effects in Samples of Young Adults.

Vaping is a fairly new and legal way young people are inhaling substances into their lungs. Very little is currently known about the immediate physiological impact or the psychosocial reasons surrounding vape use. This study used a mixed methods approach to (a) understand the short-term physiological implications of vape use compared with people who do not vape and (b) investigate the reasons people choose to vape compared with those who choose not to vape. Twenty-four people participated in the study: 12 self-identified as nonvapers, and 12 self-identified as people who vape. All participants were between 18 and 24 years old. Qualitative analysis suggested people vape because they think it is cool, think it is less risky than smoking, and enjoy the social aspects of vaping. People who choose not to vape are concerned about the unknown health implications, think it is a waste of resources, and are apathetic toward it. Quantitative results revealed statistically significant increases in heart rate and decreases in the percentage of blood oxygenation after 20 minutes of vape use. Blood pressure, respiratory rate, and blood sugar scores did not significantly change after 20 minutes of vape use. Differences in the frequencies of men and women across the two groups were found. Significant differences found for systolic blood pressure, respiratory rate, and pulmonary function test became nonsignificant after controlling for gender. Both long- and short-term effects of vaping need to be further evaluated. The psychosocial reasons why certain people vape whereas others in the same peer group do not also need to be better understood.
