Two months ago, Paul Lara saw a letter from his doctor to his insurance company. He recalls looking at the bottom of the page, next to the doctor's signature, "It says: Does this patient have cancer? He marked yes."
Only one problem: Paul Lara has never had cancer.
After decades as a commercial fisherman in Texas, Lara was badly injured on the job. In 2013, his doctor prescribed a high dose of an opioid called Subsys for Lara's back and neck pain. The fentanyl-based spray can be up to 100 times stronger than morphine.
