A search warrant issued under section 75(3) authorises an inspector executing the search warrant, in addition to the seizure of any thing of the kind described in the warrant, to seize any thing which is not of the kind described in the warrant if—
(a) the inspector believes, on reasonable grounds, that the thing—
(i) is of a kind which could have been included in a search warrant issued under this Division; or
(ii) is evidence of a contravention of this Act or the regulations; and
(b) in the case of seizure, the inspector believes, on reasonable grounds, that it is necessary to seize that thing in order to prevent its concealment, loss or destruction or its use in the contravention of this Act or the regulations.
