FDA proposes caps on nicotine in cigarettes

The FDA proposes a 334-page plan to reduce nicotine levels in cigarettes, aiming to make them less addictive. This could help 13 million smokers quit and prevent 40 million young people from starting. Anti-tobacco groups support the move, but the proposal faces uncertainty under the new administration and potential legal challenges from tobacco companies. A nine-month public comment period is underway before any action is taken.
