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.

In its last few days of power, the Biden administration is expected to officially propose a limit on nicotine in cigarettes.

The rule proposes a maximum nicotine level of 0.7 milligrams (mg) per gram of tobacco -- a significant decrease from current levels, which can range anywhere from 6 mg to 28 mg per gram. The limit would apply to cigarettes, pipe tobacco, and cigars, but not to e-cigarettes, nicotine pouches, or other products.
