Human Factors
On approach on the ILS for 18R at 1;500 feet we passed a drone hovering about 50-100 feet off the left side of the aircraft. We did not have to deviate to avoid it; but it was close by. It was black and white with four propellers. It did not move over as we went by. It just hovered in the same spot. We notified ATC tower controller. Upon landing the controller asked us more in depth questions about the drone. Being on localizer and glide slope was key here because a deviation to the left may have hit the drone. Suggestions: Not sure what to do to stop this action; except for strict enforcement of the law when these operators are caught. Had I been left of course a bit a half dot; this could have been worse.
Air carrier flight crew on an established ILS approach noticed they flew past a UAS on the left side of their aircraft. Crew notified ATC.
