  • China and USA have witnessed the highest focus from the top players in the domain. China is the biggest tobacco market globally. The increasing awareness of e-cigarettes as a substitute for tobacco products makes China the most prominent market, due to the high number of smokers in the region. Although, the adoption of vapes in the region is considerably low, the region shows enormous potential for growth in coming years.
  • In USA, the growing popularity of e-cigarettes specially among the younger generations is expected to create the market for the domain.
  • Europe is also picking pace with US and China, due to the increasing adoption of e-cigarettes as a substitute for traditional smoking products.
  • Japan and Korea have also been witnessing a growing attention of investors and manufacturers due to the popularity of heat-not burn products and other tobacco alternatives, not containing nicotine, among adolescents in the region. The legalization of only nicotine-free products in Japan has created a demand in the region that is propelling the e-cigarette market.
  • Interestingly, Canada has emerged as a major market for e-cigarettes, even though it hasn’t got much any attention in innovation and R&D. The legalization of sales and purchase of vape product (even those containing nicotine) in the region could be a major reason for the growing potential e-cigarette market in Canada.
