Logistic regression and Relative risk (RR)

In some statistical applications (eg. SAS) RR is an option in logistic
regression. This is rarely used in Scientific literature where some authors
even report odds ratios (OR) as RR. This is seen even in recent papers in
the New England Journal of Medicine.

Is there any interpretation difficulties when logistic regression models
report RR in stead of OR and why is this option seldom used.

Another question: can logistic regression models give the answer in RR in
"STATA"?
