	   Tobacco use is the #1 leading cause of  preventable deaths in the United States. Approximately 90% of adult smokers  reported smoking prior to the age of 18. Recently, Electronic Nicotine Delivery  Systems, ENDS (also known as electronic cigarettes or e-cigarettes) have  surpassed conventional cigarettes among adolescents. ENDS are considered to be  safe by the general public, however there have been no studies to determine  their long-term effects and whether they lead to diabetes, insulin resistance  or increase the rate at which cancer cells divide. The use of our mouse  electronic cigarette delivery system will allow us to deliver nicotine from  leading brands of electronic cigarettes into mice. We will determine if these  mice develop diabetes, fat depositions in their liver or, in mouse models of  breast cancer, if there is an increase in the rate of cell division and tumor  growth. Our mouse electronic cigarette delivery system will allow us and other  investigators to study other potential negative effects of ENDS, including  their effects on lung function and potential to induce a variety of cancers. We  will report our results in high quality, peer-reviewed journals and scientific  conferences such as TRDRP conference, the annual meeting of Society for  Neuroscience, the annual Drug Abuse Research Symposium at Charles R. Drew  University, and the translational nicotine research group symposium at UCLA. Of  paramount importance in the study community where smoking is abundant and where  there are high tobacco-related health disparities, researchers will bring  awareness about our study and outcomes to residents, community and faith-based  organizations. Our study will help policy makers determine whether electronic  cigarettes should be regulated as conventional cigarettes are currently  regulated. As our study is looking at electronic cigarette vapors, it will also  inform policy makers on the safety of second-hand electronic cigarette vapor  and whether electronic cigarettes should be banned from public use.  	   |
