The expansion of the e-cigarette industry has been largely facilitated by multifaceted marketing strategies that integrate traditional advertising with digital media. This chapter critically examines the industry’s use of social media platforms, influencer marketing, and user-generated content to promote e-cigarette products, particularly among adolescents and young adults. Key marketing tactics include strategic packaging design, a diverse range of appealing e-liquid flavors, and misleading health claims. The industry also employs in-store promotions, direct marketing, discount incentives, loyalty programs, and event sponsorships to enhance visibility and foster consumer loyalty. Despite claims of targeting adult smokers, marketing practices continue to appeal to youth, posing significant public health risks. The chapter underscores the urgent need for comprehensive regulatory frameworks and targeted educational interventions to mitigate these risks. Understanding the scope and impact of these marketing strategies is essential for policymakers and public health professionals in developing effective responses to safeguard vulnerable populations from the harms of e-cigarette use.
