§ Mr. Livingstone
To ask the Secretary of State for Health what assessment of the health effects of CR gas sprays has been made by the medical officers of his Department since 1991; how many published and internal papers have been written by his Department's medical officers on this subject since 1991; and what are the current security classifications of the internal reports. 
§ Ms Jowell
No scientific assessments of the health effects of CR gas sprays have been made by medical officers of the Department in the period since 1991. No papers have been published by the Department's medical officers on the subject. However, in the book "Chemical Warfare Agents: Toxicology and Treatments" published by Wiley in 1992 (ISBN 0–471–95994–4), a chapter authored by a medical officer of the Department made reference to the subject.
