No person shall display in any business any drug paraphernalia in a manner so that it is open to viewing by a minor. It is not a violation of this section to display drug paraphernalia in a business, separate room or enclosure to which entry by minors is prohibited. The entry of each business, separate room or enclosure to which the entry by minors is prohibited shall be posted with a sign that is conspicuously visible notifying the public that minors are excluded.
