Dr. Ritchie and Dr. Nevin, thank you very much.
I'm a former service member and served 23 years in operational units. Obviously, when you have personnel, and you want to manage personnel, often you have a large number of troops who you're trying to deploy very quickly sometimes, and you need to prescribe drugs.
I was very interested, Dr. Ritchie, that you say it shouldn't be prescribed at all. Could there be circumstances when this drug should be prescribed in operations? It doesn't have to be taken every day; it has to be taken on a periodic basis. If you are in operations, and you don't have access to the prescription medication that you might need in theatre, could there be occasions when it should be prescribed?
