Electronic cigarette experiencing a phenomenal annual growth rate is aggressively eating into tobacco market. It’s not surprising that some analysts start to predict e-cigarette will eventually take over tobacco market within a decade. Regrettably, China market remains unknown to the e-cigarette world. It’s absurd given that the first e-cigarette was invented in China, and the world’s 95% of e-cigarettes are being produced in Shenzhen, China. Vape pen brands, China’s OEM manufacturers or even major international tobacco giants are all eyeing up this huge potential market. Who wouldn’t? China is the world’s largest producer and consumer of tobacco products after all.
