Human Factors; Procedure
Cleared to takeoff; I [initiated and the] First Officer set the power. At the 80 KT call I saw a helicopter to the right of the runway [drifting] toward my runway. As it began to cross my runway I called abort and aborted the takeoff.  The helicopter pilot said he was sorry. The Tower Controller said the helicopter was cleared to takeoff and stay west of our runway. However that pilot didn't catch the 'stay west' part. So; he flew east right across my take off path.Beware of helicopters.
I was Ground Control; Flight Data and CIC [Controller In Charge] in the Tower at the time of the occurrence. A helicopter on the FBO ramp; was requesting to depart east. I informed the Local Controller of the helo's request and continued with my duties of making ATIS. I looked up to see the helo departing to the east and the CRJ aborting his takeoff.I did not hear the clearance exchange between the Tower and the departing traffic therefore; I can't say for sure what I would recommend for phraseology; etc. However; I do think that having a standalone CIC may have helped. This would have been a person that could have been listening to the frequency and caught the helo departing across the runway.
A departing CRJ-200 flight crew rejected their takeoff just after reaching the high speed regime when a departing helicopter drifted over their runway.
