VAPING DANGER: A HIDDEN THREAT AMONG MALAYSIA’S YOUTH Over the past few years, there has been a rising trend of young adult vapers presenting to health clinics across Malaysia with signs and symptoms such as dizziness, vomiting, eye redness, abnormal behaviours and seizures. Publishing this case aims to raise awareness among primary care doctors regarding the latest trends in substance use among Malaysian young adults and school-aged teenagers. Without prior experience in managing addiction cases or a high index of suspicion for substance use, such cases are at risk of being misdiagnosed and mistreated, especially since many new psychoactive substances (NPSs) cannot be detected with standard urine drug test kits.
