Question to the Home Office:

To ask the Secretary of State for the Home Department, what assessment she has made of the (a) effectiveness and (b) speed of lab testing oral fluid rather than blood samples as evidential confirmation of drug driving offences.

No such assessment has been made. We have been advised by the National Police Chief’s Council that, despite some backlogs with blood samples last year, toxicology supply has now significantly increased, and all backlogs have been cleared.

We will continue to monitor the situation as appropriate.
