Ms Paula Hilman:

We have carried out more than 30,500 of them this year. In the past year, they averaged approximately 5,000 a month. At those checkpoints, we test for both alcohol and drugs. The equipment available plays a role. In 2020, Professor Cusack released the last drug testing machines from stations. We found that having them mobile in the vehicles was much better. From that date, we had the old device in the vehicles. Having more of them has contributed to the increased detection of drugs since 2019. We now have the drug wipe. We test for those at both checkpoints.
