US bans Juul but young vapers are already switching to newer products

Analysis: Juul is only the fourth most popular e-cigarette with adolescents, who are opting for disposable alternatives

This week, the US effectively banned Juul after the Food and Drug Administration ordered the e-cigarette maker to remove its popular products from the marketplace.

Experts have hailed the move as significant. But they are also concerned that such efforts are failing to keep up with a fast-moving vaping industry - one where young people leap quickly from one product to another.
