The Justice Department announced Tuesday multiple large cigarette companies will be required to provide signs at retail stores warning of the health issues associated with smoking starting in July 2023.

The move comes as the Justice Department has worked for over 20 years to hold tobacco companies accountable for not being transparent about the risks. Smoking causes about 30% of all cancer deaths in the U.S.

"Cigarette companies misled the public for decades about the health risks of smoking and were ordered by a federal court to implement a series of corrective measures," said Principal Deputy Assistant Attorney General Brian Boynton, head of the Justice Department's Civil Division, said in a press release.

"All of these measures have been implemented, except one—the display of corrective statements in retail stores that sell cigarettes. Today's order requiring implementation of that remaining remedy is a major achievement that will educate American consumers and save lives," Boynton added.

The new rule was court-ordered from a 1999 lawsuit against defendants Altria, Philip Morris USA Inc., R.J. Reynolds Tobacco Company, and four cigarette brands owned by ITG Brands.

The companies are ordered by the court to display "eye-catching" signs for two years.

The warnings will include statements like, "Smoking cigarettes causes numerous diseases and on average 1,200 American deaths every day," and "The nicotine in cigarettes is highly addictive and that cigarettes have been designed to create and sustain addiction."

"So-called light, low-tar and natural cigarettes are just as harmful as regular cigarettes" and "Secondhand smoke causes disease and death in people who do not smoke," will also be part of the campaign, according to the release.
