The smoking prevalence among Korean adult men has reached to 38.1% in 2017, which was the lowest in Korea's history. JUUL will be sold in Korea. This study has discussed: what JUUL was; how people use JUUL; what knowledge we have had about JUUL so far; what kind of marketing tactics has been employed; and how we prepare the introduction of JUUL in Korea. JUUL is a new electronic-cigarettes (e-cigs) shaped like a USB flash drive and is divided into two parts, device and pod. A pod contains nicotine liquid and flavors, such as Mango and Mint. JUUL contains more nicotine than many other e-cigs. JUUL uses nicotine salt which can increase the rate and amount of nicotine delivered into the blood. Since its introduction in 2015, JUUL has been the top-selling e-cig brand in the US. Due to JUUL, e-cig use among the US high school students rose by 78%, and more than 3.6 million middle and high school students used e-cigs. The recent evidence showed that nicotine in JUUL pod was much higher than other e-cigs. US FDA has taken some actions to address this crisis. JUUL will be treated as same as other tobacco products in Korea. The government must closely monitor JUUL's marketing activities, particularly, its flavor marketing. Parents and teachers should be educated about JUUL and can recognize that it is a tobacco product. This study calls the government, experts and civil societies to take urgent actions to protect our youth from JUUL.
