Officer in Charge of the Young sector, which includes Grenfell, Inspector Jacob Reeves said there were three positive drug driving tests in Grenfell last week.
"Last Thursday, Friday and Saturday the Southern Traffic Group spent three days in Young Sector patrolling areas the community have given us feedback about," Inspector Reeves said.
"A regrettable result with 13 positive drug tests. Seven in Young, three in Harden and three in Grenfell."
Inspector Reeves wanted to stress to the community that motorists driving with either drugs or alcohol in their systems is a fatalistic mix.
"Drug and/or alcohol intoxication is one of the Fatal 5 on NSW roads," he said.
"The NSW Centre for Road Safety advises that the presence of illegal drugs is involved in around the same number of fatal crashes as drink driving - that's about 14 per cent of fatal crashes."
According to Inspector Reeves the issue isn't only in the Young sector but across the state with a devastating number of people who have potentially died due to drugs and/or alcohol in their system while behind the wheel.
"In the 12 months to 1 March 2021, 294 people lost their lives on NSW roads.
"Looking at the 14 per cent presence of illegal drugs in fatal crashes, there were potentially 41 people that could still be with their family, friends, sports team, job and social groups but for drug driving.
"They are no longer with us."
Inspector Reeves said there will be an increased police presence over the roads over the next few weeks as police try to crack down on dangerous activities on local roads.
"Young Sector General Duties, Young Highway Patrol and the Southern Traffic Group will be focusing on impaired driving, distracted driving and dangerous driving in coming weeks," Inspector Reeves said.
"The community can expect to see Highway Patrol in the backroads and on suburban streets."
