Zyn, a small sachet with nicotine and flavorings, has sparked concerns that it could lure teenagers into smoking.

Zyn, the new tobacco product launched by Philip Morris International, has stirred controversy as videos of young people using the sachets racked up millions of views on TikTok and other social media platforms. Concerns center on the potential for Zyn to become a new nicotine product that appeals to teens, similar to how Juul triggered a surge in e-smoking.
