The Food and Drug Administration put Juul Labs Inc., on notice Monday for allegedly advertising their products as “much safer than cigarettes” to kids in a school presentation.

The FDA is investigating House Oversight Committee testimony from two teens that they saw a Juul representative give a presentation in school saying not only that the products are “totally safe,” but also that each student “should mention JUUL to his [nicotine-addicted] friend … because that’s a safer alternative than smoking cigarettes, and it would be better for the kid to use.”
