State officials hailed the report as evidence that state police are aggressively combatting drug dealers who often drive through the state.
"It is impressive," said Capt. Greg Shipley, a state police spokesman.
Some civil libertarians questioned whether the state has sacrificed rights for results.
"Efficiency in seizure of drugs or any other contraband is not necessarily (compatible) with the Constitution," said Susan Goering, executive director of the Maryland chapter of the American Civil Liberties Union.
The ACLU has charged that state police have stopped without cause a disproportionate number of black motorists.
"We happen to have data and statistics to show that they have been," Goering said.
Shipley, however, countered that the state police always have adhered to the Constitution.
"We believe the people of Maryland have given us a mandate for stopping the flow of drugs coming into our state and we will continue to do that," he said.
Shipley praised the skill and tenacity of state troopers who have detected drugs during routine traffic stops. He also acknowledged that Maryland has a number of busy thoroughfares that carry the drug trade up and down the East Coast.
"We are right in the middle of a pipeline... We have said this repeatedly about all of our interdiction efforts," he said.
Shipley said about 40 percent of the drugs intercepted nationally are seized by law enforcement officers on patrol.
In addition to the crack, state police in 1996 seized 220 pounds of powdered cocaine, 130 pounds of marijuana, four pounds of heroin and more than $1.6 million in money connected to the drug trade, according to police records.
During the stops, troopers recovered 41 guns, 25 knives and eight other deadly weapons, police said.
Shipley said the state is running a little below last year's rate.
"Who knows what the next two months will bring," he said.
