HC Deb 10 April 1986 vol 95 c154W
Mr. Chris Smith

asked the Secretary of State for the Home Department whether he has arranged for any tests to be carried out to establish the extent of any carcinogenic properties of CS gas; and if he will make a statement.

Mr. Giles Shaw

No. Following the "Report of the Enquiry into the Medical and Toxicological Aspects of CS (Orthoclorobenzylidene malononitrile) (Cmnd. 4775), a number of scientific studies in this area have been published. I understand that no positive correlation between CS and cancer has been demonstrated.
