The use of e-cigarettes and vape pens has grown in popularity especially among the high school and college aged population. This is a cause for concern because due to its relative novelty not much is known about the long-term impact of vaping. Cannabidiol (CBD) is a compound derived from hemp that is being used in vape pens. Although the oral intake of CBD has been researched, there is still much to be learned about the impact CBD has when vaped. Thus, the purpose of this pilot study is to gather data on cardiovascular, respiratory, and mental health of participants who vape CBD but do not smoke traditional cigarettes. Participants were asked to fill out surveys on their anxiety, depression, past medical history, and alcohol use. Each participant then performed a VO2max test and spirometry test to measure cardiorespiratory function. Data was compared to reference values based on age and gender. Our participants showed very poor cardiorespiratory health and elevated levels of reported anxiety and depression. We speculate that there may be a relationship between vaping CBD and reduced cardiorespiratory function; however, more data needs to be collected to confirm this assumption.
