HC Deb 12 June 1958 vol 589 c33W
57. Dr. Bennett

asked the Secretary of State for the Home Department whether in view of his reference to the Poisons Board of soporific drugs combining carbromal and brom valetone, he will similarly refer aspirin as having similar properties of habit formation and more than 10 times greater record of use in attempted suicide.

Mr. R. A. Butler

No. Carbromal and bhom valetone were referred to the Poisons Board because of evidence that preparations containing them can cause harmful personality changes if consumed to excess. This does not apply to aspirin.
