Professor Denis Cusack:

The breathalyser tube for alcohol is less than €1. There are 30,000 of these drug testing devices and I think 13,500 have been done, which is much fewer than for alcohol because these cost about €15 or €16 per device and it takes a little bit longer. Therefore, I do not think we will ever reach the same level of random drug testing as with alcohol. Again, that is a worldwide experience. However, it is out there and that is why people know that if they take cannabis, cocaine or their benzodiazepines, the enforcement and equipment are there. That is a positive message.
