addition to providing critical information at an important time in the emergence of these products, the study has supported the efforts to understand the e-cigarette industry by regulatory agencies such as the FDA. Given that most of the knowledge of “puff topography”, or the volume of cloud, duration of the inhale, and the concentration of drug in the cloud, is promulgated by users, this research has contributed to the scientific foundation for electronic e-cigarette usage. Recently, the research group was asked to provide presentations and our list of publications to the U.S. Food and Drug Administration and to U.S. Department of the Navy, which is evaluating whether 5 This resource was prepared by the author(s) using Federal funds provided by the U.S. Department of Justice.

So, while the impact on the criminal justice system is evolving, significant implications exist in other forums. Design Methods and Results The following aims and experiments were identified within the proposal. Within each, specific experimental goals and results are described. In addition to pursuing these aims, we also monitor the current state of e-cigarette usage, messaging in the media, and legislation and regulation. Goal: The goal was to identify information and resources to assist ongoing research to understand the forensic impact and implications of e-cigarettes. Information gleaned in the process of this study will assist decision-making regarding criminal justice and public education. • Modifications and adulterations to electronic cigarettes and e-liquids, including illicit drug delivery, are described and promulgated by experienced users through videos, social media, and user blogs. • All fifty states have developed policy in at least one of these five areas: sales to minors, defining e-cigarettes as tobacco products, bans on use in public, taxes, or other regulations. • Media has reported deaths due to e-liquid consumption. • Over the course of the 2+ year project, drug forum conversations evolved rapidly to discuss modifications and adulterations to e-cigarettes and e-liquids. o Recent conversations have included drugs such as Kratom (mitragynine), synthetic cannabinoids, synthetic opioids, and blue lotus (apomorphine and nuciferine) o Natural products in addition to illicit substances continue in the threads. o New e-cigarettes models emerged for the specific use of waxes, dabs, and dry natural products. o Modifications to the atomizers, mostly with regards to coil configurations, escalated as e-cigs became more technologically advanced. o Users continued to advocate regularly, despite prohibitions to public vaping, that the ease of transporting illicit substances and vaping illicit substances in public was a bonus for adopting the method. • After the FDA banned the sale of products, websites had to stand-up a screening process to make sure that people were >18 years old. We monitored the complexity of this and have been challenged by more reputable websites who have questioned the identity of the purchaser. Since the credit card had the university address, the vendor was unable to “confirm” identity and age of the purchaser. Vendors with questionable e-liquid products have had no problem with the disconnect between the address of the credit card and our identity. While there is no way to know without further investigation, the difference between the two types of vendors has been observed. • An evaluation of historical patents was performed to create a timeline of e-cigarettes and their mechanisms for operation, particularly as their construction evolves. Aim 1 Develop reliable, validated analytical methods to support the efficient and thorough analysis of e-cigarette devices, device components, and aerosol for pharmaceuticals in adulterated, unadulterated, and self-prepared formulations. 6 This resource was prepared by the author(s) using Federal funds provided by the U.S. Department of Justice.
