Texas Attorney General Ken Paxton said Tuesday he is launching an investigation into Walmart's opioid sales to determine if the retail giant improperly filled prescriptions. 

Paxton issued a civic investigative demand to Walmart for possible violations of the Texas Deceptive Trade Practices Act, according to a news release from his office. 

The CID is related to the promotion, sale, dispensing and distribution of prescription opioids

"I have fought for Texans who have been tragically impacted by the illegal marketing and sale of opioids, which have caused addiction and the untimely deaths of thousands of people each year," Paxton said in a release. "I am committed to holding pharmacies accountable if they played a role in this devastating epidemic."

The investigation will center on Walmart's compliance with submitting documents related to opioid orders dating back to January 2006 to the Drug Enforcement Administration and state agencies. 

In a statement to Fox News, Walmart said it has "never manufactured, marketed or promoted opioids, and pharmacists aren’t doctors and don’t write opioid prescriptions."

"We are confident in our record helping fight the opioid crisis, and we are proud of our pharmacists, who help patients understand the risks about opioid prescriptions, and have refused to fill hundreds of thousands of opioid prescriptions they thought could be problematic," the statement said. "As a result of Walmart’s refusal to fill opioid prescriptions, many health regulators (including the Texas Medical Board), medical groups, doctors and patients say that Walmart is going too far in refusing to fill opioid prescriptions, and even say we are improperly interfering in the doctor-patient relationship. Walmart and our pharmacists are torn between the demands on pharmacists imposed by opioids plaintiffs on one side and health agencies and regulators on the other, and patients are caught in the middle."

The federal government sued Walmart in 2020 over its role in fueling the nation's opioid crisis.

The Justice Department’s lawsuit claimed that Walmart sought to boost profits by understaffing its pharmacies and pressuring employees to fill prescriptions quickly. That made it difficult for pharmacists to reject invalid prescriptions, enabling widespread drug abuse nationwide, the suit alleges
