The Food and Drug Administration is proposing regulations on the fast growing e-cigarette industry.
Federal health officials want to ban sales to minors and require warning labels.
New products would also need to be approved.
The regulations would not prohibit television ads, flavored products or set product standards.
But the agency could propose more restrictions in the future.
Members of the tobacco industry and public will have 75 days to comment on the proposal before the FDA determines if the rules will go into effect.
However, some believe the final decision could be made in court.
"I think anything sold to public should be researched before it's sold to the public. They should know what's good, what's bad about it and they should put it out there," said one New Yorker.
"I don't think they should sell it to minors, I guess they should do more research and see but it's definitely better than smoke," said another New Yorker.
Nearly $2 billion worth of e-cigarettes were sold last year.
