* § 391-s. Restricted access to retail sale of dextromethorphan, commonly known as "dxm". 1. No retail establishment offering for sale any product or products containing as an active ingredient dextromethorphan, shall permit the sale of such products to persons under the age of eighteen without a valid prescription. Retail establishments shall require proof of legal age for purchase of such products. Such identification need not be required of any individual who reasonably appears to be at least twenty-five years of age, provided, however, that such appearance shall not constitute a defense in any proceeding alleging the sale of any product or products containing as an active ingredient dextromethorphan to an individual under eighteen years of age. Any retail establishment which violates the provisions of this section shall be subject to a fine of two hundred fifty dollars for each such violation.

2. As used in this section "retail establishment" means every vendor that in the regular course of business sells products containing dextromethorphan at retail directly to the public including, but not limited to, pharmacies, grocery stores, and other retail stores.

3. This section shall supersede any local laws or ordinances regulating the sales of products containing dextromethorphan.
