medical doctors

Why is it that all of the doctors in Chicago, IL are paranoid (like they've been smoking way too much bud) to sign applications stating patents have xyz medical conditions? Their excuses are "I don't know how much to prescribe"or "I can get in trouble"... uhhhh they do not prescribe ANYTHING...
