Substance misuse in prison, to which the noble Baroness refers, is of course a major issue, and prison security has a crucial role to play in reducing it. I should also say that the use of illegal drugs can impact on routine healthcare for all prisoners, as resources have to be directed to the more immediate cases. Noble Lords may remember that we recently had delegated legislation to ensure that nasal Naloxone could be administered, including by prison staff, to prevent opioid-induced emergencies. All these things will help, and substance misuse support is available in all prisons in line with the national service specifications, but we are working across government to see what more we can do. It is a big issue.
