Often marketed as a "safer alternative," e-cigarettes (vaping) carry significant hidden health risks. This video dives into cutting-edge research revealing the impact of vaping on cardiovascular health and sleep quality. We break down the alarming findings from a systematic review, including the heightened dangers faced by "dual users" (those who use both conventional and e-cigarettes). We also examine Varenicline's efficacy in aiding vaping cessation and its common side effects. Finally, we highlight the surprisingly high smoking prevalence among health science students in low- and middle-income countries (LMICs), discussing the socio-cultural factors and mental health challenges driving this trend, and outlining essential policy recommendations to safeguard our future healthcare leaders.
