The Biden administration released a proposal Wednesday to dramatically reduce nicotine levels in cigarettes, a move that anti-smoking advocates believe would save millions of lives even as it threatens the powerful tobacco industry.

Officials proposed limiting the amount of nicotine to make cigarettes less addictive, but it's unclear if the incoming administration will offer support.

On Wednesday the Food and Drug Administration published a proposed rule that would slash the amount of nicotine allowed in cigarettes and certain finished tobacco products.
