Narrative:

On a regularly scheduled flight from st louis, mo, to houston, tx, a cabin attendant informed the cockpit that a passenger had repeatedly left his seat while the fasten seat belt sign was on to use the lavatory and was snorting a substance in his seat that appeared to be an illegal substance, presumably cocaine. The passenger's behavior was erratic but not completely disorderly. The captain instructed me (flight engineer) to contact company management for a coordinated response to the passenger activity. The cabin attendant brought an unused package of the suspect substance to the cockpit as evidence. Company advised us (the crew) to call for police to meet the plane in houston. We did. Police met the passenger as he deplaned and later arrested him for parole violation. We did not learn what he as snorting or if the packets of substance were illegal. The whole series of events transpired without much disruption to the safety of flight. The cockpit crew, cabin crew and company were informed of all events and decisions. The nature of the problem was dealt with without flight disruption. All in all, the situation was uncomfortable and added to the workload of the crew, but despite the possibility of illegal drugs and a passenger under their influence, no safety infractions occurred.
