Mr. Seán Quigley:

That is part of the work of the technical staff in the bureau. There are 81 drugs there. It is possible that they will come across new drugs that were previously unrecognised. There are still three main drugs, as I outlined earlier. The important thing is to keep abreast of any new drugs that may be in use of which we were not previously aware.

Regarding the alcohol interlock device referred to by the Deputy, the bureau has a role in testing and approving those devices. They are submitted by companies which want to have their systems approved in order that we will approve them. They are not mandatory. A number of transport companies use them on a voluntary basis but they are not statutorily required.
