(b) Any cigarettes that have been sold, offered for sale or possessed for sale in this state, in violation of subsection (b) of § 4-28m shall be deemed contraband goods under § 12-305 and such cigarettes shall be subject to seizure as provided in § 12-305. All such cigarettes so seized shall be destroyed and not resold.

(c) The Attorney General, on behalf of the commissioner, may seek an injunction to restrain a threatened or actual violation of subsection (b) of § 4-28m or subsections (a) or (d) of § 4-28o by a stamper and to compel the stamper to comply with said subsections. The commissioner may adopt regulations, in accordance with the provisions of chapter 54, to effect the purposes of this section.
