The dismissal and pending investigation of Carmen Puliafito came following a report in the Los Angeles Times detailing a pattern of illegal drug use on the USC campus.

While the details in Puliafito's case are pretty pretty singular, the former dean of the USC Keck School of Medicine is not the only medical professional to use drugs illegally.

People in the health care field are no more or less likely to experience drug addiction than the rest of us, estimated to be between 8%-13% of the US population. But that doesn't mean the circumstances are the same for health care workers as it is for everyone else. For example, they're likely to have access to addictive substances,  and due to their training, can be better at concealing their drug use.

But according to Carrie Kappel, the Associate Director of the Health Care Professionals Program at the Hazelden Betty Ford Foundation, the most unique obstacle for people in the medical field-- shame.

"Often health care providers with a substance use disorder are extremely hard on themselves," said Kappel in an interview with Take Two host A Martinez. "Harder than other people are."
