As AI redefines advertising, consumer protection must adapt. AI is now deeply woven into our daily behaviors and perceptions—it is intrusive, embedded, and unavoidable in modern business. This reality poses an urgent question: are our legal frameworks and enforcement agencies equipped to handle the algorithmic age?
Consumer Protection Law
Please note that this is the most important section of the law: Section 22 of the Consumer Protection Act B.E. 2522 (1979)
Section 22. Advertising must not use statements that are unfair to consumers or that may cause harm to society as a whole, regardless of whether such statements concern the origin, condition, quality, or characteristics of the goods or services, as well as their delivery, supply, or use.
The following statements are considered unfair to consumers or that may cause harm to society as a whole:
(1) Statements that are false or exaggerated.
(2) Statements that cause misunderstanding regarding the essential characteristics of the goods or services, whether or not they are made by using or referencing academic reports, statistics, or anything else that is untrue or exaggerated.
(3) Statements that directly or indirectly encourage illegal or immoral acts, or lead to the degradation of national culture.
(4) Statements that cause division or undermine unity among the people.
(5) Other statements as specified in ministerial regulations. Statements used in advertising that the general public can know are definitely untrue are not prohibited in advertising under (1).
The Act came into effect on November 8, 2025. It emphasizes stricter advertising regulations, prohibiting advertisements that encourage drinking and those that use hidden names/logos. However, it allows for the display of information or promotional materials according to new guidelines.
The sale of alcoholic beverages remains prohibited on religious holidays and during specified times.

Unlocking Information but Prohibiting Persuasion: Advertising that provides knowledge or promotional materials is now permitted, but advertisements aimed at directly or indirectly encouraging people to drink alcohol remain prohibited.
Note:
Alcoholic Beverage Control Act B.E. 2568 (2025) is one of the most debated and litigated pieces of legislation in the country.
The law is fundamentally designed to regulate intent and perception, rather than just explicit text. This creates a significant "gray area" where linguistic nuance and cultural context collide.

According to data released by the National Economic and Social Development Council (NESDC), consumer complaints have surged by nearly 40% in a short period, primarily due to being deceived by “fake advertising,” especially advertisements that use AI to create incredibly realistic images of products, services, or locations, making it difficult for consumers to distinguish them from real. Some businesses exploit loopholes in the law, using AI-generated images to promote their goods or services, leading to increased consumer rights violations.
The Office of the Consumer Protection Board (OCPB) expresses its concern and urges consumers to exercise extreme caution when purchasing goods and services advertised online, especially in an era
1. Check the source of the advertisement to ensure it is a trustworthy platform or website with clear contact information;
2. observe details in the image, such as background abnormalities, facial details, hands, or text, which are often areas where AI makes mistakes;
3. read reviews from real users or gather information from multiple sources before making a decision; and
