"If you are trying to be a little healthier to reduce the amount of nicotine that you're using, this is a real effective method," said Trevor Fukuda, who took up e-cigarettes four years ago.

"It happens in classrooms, in bathrooms, it is an epidemic," said San Francisco City Attorney Dennis Herrera, who's taking on the Federal Drug Administration for failing to conduct a pre-market review of these products.

Here's what Health and Human Services tell ABC7 -- tobacco use by adolescents has declined substantially in the last 40 years.

On Tuesday, Supervisor Shamann Walton introduced legislation that would essentially ban these products in San Francisco until the FDA acts. Assuming that it passes, the ban will go into effect 30 days later. That also means that these products could not be ordered online and mailed to a San Francisco address.

"With that said, we'll be working hard to move as fast as possible," said Walton.
Su Wai works at the California Tobacco Center on Polk Streets. Vaping has helped her quit smoking cigarettes -- now she says a ban would force her to quit altogether.
"That would help me to really quit if it's not available anymore. That would help me cut off, no going back to cigarettes," said Wai.
