Zusammenfassung:	A variable parameter smoking machine for smoking one or more cigarettes that allows adjustment of the puff flow, duration, and interval for the cigarettes being smoked. Cigarette holders are placed in fluid circuit parallel with dummy air-flow resistance valves, and either the holder or dummy load is placed in operative communication with a continuous vacuum source by a solenoid-operated valve associated with each holder and dummy load. A flow-adjustable valve is also associated with each holder and dummy load. Each holder-dummy-valve system is connected to a pressure manifold, which in turn is connected through a circuit having a flowmeter and flowmeter bypass line arranged in parallel to the continuous vacuum source.
