“Juuling,” a type of discreet e-cigarette smoking, is reportedly gaining popularity with teens—and high schools have taken notice. Juul devices resemble thumb drives, making them hard to spot for those not in the know (like parents, teachers, and administrators). Because of this, high schools are issuing informational warnings about the devices as they see more students use them in class, bathrooms, and more. Starter kits only cost $49.99 with many available on the resale market for users-under-21, lowering the barrier to entry. (Boston Globe)
