After a year of traveling throughout the country, Facebook CEO Mark Zuckerberg saw the opioid crisis up close, and he claims that the scope of it shocked him. Yet he seems oblivious to the fact that Facebook is riddled with illegal ads marketing the addictive opioid pain relievers.

Sellers in the United States and overseas are using Facebook pages and videos in their effort to peddle drugs that require a prescription by U.S. law, CNBC reported.

Zuckerberg said he became aware of the scale of the opioid crisis during his 2017 travels across the country.

It’s been one month since President Donald Trump declared the opioid addiction crisis a national emergency. But Facebook users are still able to search for drugs like Oxycodone, Hydrocodone, and Percocets just by typing in the name of their drug of choice, followed by “for sell” rather than “for sale,” according to CNBC.

A conservative like Dennis Michael Lynch is targeted repeatedly, but pages and posts selling illegal drugs are able to operate on Facebook for months at a time.

“Zuckerburg and his apostles at Facebook have been so busy curbing the opinions of conservatives that they have failed to realize what is really happening in the U.S.,” Lynch observed.

CNBC said they conducted a simple search and easily found posts offering drugs for sale. They notified Facebook of the posts and the company said it would remove them. Twelve hours after that, many of the posts were still visible.

In a statement from Facebook to CNBC, it is suggested that Facebook currently relies on users to police the site for illegal drugs sales, instead of designating employees to this task.

“Anyone can report content to us if they think it violates our standards,” Facebook said in a statement to CNBC. “People can flag pages, profiles, individual content, and/or comments to us for review.”
