Maryland’s attorney general charged on Thursday that opioid maker Insys Therapeutics and local healthcare providers gave a powerful opioid to patients who didn’t need it, and exacerbated the opioid epidemic in the state.

Maryland wants Insys to pay the state more than $20 million it made in revenue from its alleged conduct. Maryland is the latest state to target an opioid maker for deceiving consumers or hiding the abuse potential of opioids.
