HC Deb 24 January 1968 vol 757 c130W
97. Mr. Roebuck

asked the Minister of Transport what inquiries she has made in connection with the breathalyser test into a product called Alcokill which is intended to be sprayed into the mouths of motorists to mask the smell of alcohol and whether she will make a statement

Mr. Carmichael

Devices such as this have been tested at the forensic science laboratories: the tests have shown that mouth sprays only mask the smell of small quantities of alcohol, and only for a short time. A driver who is over the limit is most unlikely to escape detection by using one.
