One can drink expired beer without fear of health problems. However, beer is not as flavorful beyond the expiration date. Most beer is not meant to age, so there is no benefit to drinking it beyond its expiration or "best before" date.
Hop-forward styles such as India pale ales tend to lose their flavors the fastest, after about 3 to 6 months, since the compounds responsible for hop flavor and aroma are very volatile.
