A new study reveals patients given a so-called "safer" opioid have a higher chance of prolonged use.

This, even though the drug has a low risk of addiction.

Research published in the BMJ says about 7% of patients had at least one refill between 90 and 180 days after surgery.

And according to UPI, those patients were likely to have been prescribed tramadol.

Tramadol is considered a schedule II drug, the highest classified drug with an accepted medical use.

It entered the market in 1994 and wasn't considered a controlled drug until 2014.

Still, the researchers think it's time for the Drug Enforcement Agency to start closely monitoring the use of tramadol to prevent its overuse.
