U.S. prosecutors in Virginia are probing whether Facebook-parent Meta’s social media platforms facilitated and profited from the illegal sale of drugs, the Wall Street Journal reported on Saturday, citing documents and people familiar with the matter.

The prosecutors sent subpoenas last year and have been asking questions as part of a criminal grand jury probe, the report said, adding that they have also been requesting records related to drug content or illicit sale of drugs via Meta’s platforms.

The Food and Drug Administration has also been helping with the investigation, the newspaper added. It noted that investigations do not always lead to charges of wrongdoing.
