4.120.010 - Purpose.¶
(a) Regulating commercial advertising of alcoholic beverages, cannabis, cannabis products, and cannabis activity is a reasonable and necessary means to protect and promote the general welfare of the children and minors of San Mateo County exposed to various media advertising alcoholic beverages, cannabis, cannabis products, and cannabis activity.
(b) Judicial precedent has repeatedly recognized that children and minors deserve special consideration because they lack the ability to assess and fully analyze the information presented through advertising.
(c) These regulations promote the general welfare and temperance of children and minors and are intended to help reduce the illegal consumption and purchase of alcoholic beverages, cannabis, and cannabis products by children and minors by limiting their exposure to the advertising of alcoholic beverages, cannabis, and cannabis products on certain billboard structures.
