Gullible – doctors can be so easily manipulated:

Emily, 22, got a prescription for Ritalin during her last year of college. She giggles as she recounts exaggerating her symptoms during 15-minute meetings with a “bottom-of-the-barrel” doctor her school provided. (The drugs can only be prescribed by seeing a doctor in person.)

The doctor become suspicious when she admitted that she wasn’t taking Ritalin every day, Emily says. But he didn’t press her on it.

Instead, he renewed her prescription, eventually increasing the dosage to 20 milligrams from the original 5.

“I wasn’t telling him I was taking it to stay up at night, because I know that’s not really the best thing to say,” Emily says. “I was just saying, ‘I only take it when I really need it because I don’t want to be dependent on it.’ Every doctor wants to hear that.”
