Understanding Thailand’s drinking age from a legal perspective
Thailand’s drinking age and the regulation of alcohol consumption are key public health issues tied to societal concerns such as youth protection, road safety, and tourism regulation. Both individuals and companies need to understand the relevant framework to stay compliant.
The Thai drinking age, long set at 20 years old, reflects these underlying objectives and the current legal framework is primarily governed by the Alcoholic Beverage Control Act B.E. 2551 (2008), along with various ministerial regulations and local administrative orders.
However, recent developments, including a proposed alcohol control bill submitted to the Thai Parliament in January 2025, suggest a renewed commitment to enforcing and possibly tightening the legal regime surrounding alcohol.

The historical and current legal framework of Thailand’s drinking age
Thailand’s drinking age before 2008
Prior to the enactment of the 2008 Act, Thailand’s approach to alcohol regulation lacked a cohesive and centralized legal instrument. Instead, various rules existed under local administrative orders, public health directives, and royal decrees. The legal drinking age was vaguely defined, often enforced only during religious holidays or through discretionary policing. The absence of a unified legal threshold created uncertainty for foreign nationals and undermined the country’s efforts to control underage consumption.
In the 1990s and early 2000s, campaigns spearheaded by the Ministry of Public Health and non-governmental organizations such as the Thai Health Promotion Foundation began advocating for stronger statutory protections. These efforts led to the drafting of a comprehensive legal text that would serve as the first nationwide regulatory regime.
The Liquor Act B.E. 2493 (1950) was one of the earliest instruments to introduce basic prohibitions on alcohol sales to minors. However, it lacked precise definitions and age benchmarks. Enforcement relied on local discretion, which often failed to achieve national consistency. As tourism increased and alcohol consumption among Thai youth rose, policymakers began calling for stricter norms.
The period preceding the 2008 reform was thus characterized by fragmentation and weak enforcement, which resulted in varying interpretations of the Thai drinking age across jurisdictions. This legal vacuum laid the groundwork for a robust centralized statute.
The key 2008 Alcoholic Beverage Control Act
The Alcoholic Beverage Control Act B.E. 2551 (2008) was enacted to regulate the manufacture, sale, promotion, and consumption of alcoholic beverages in Thailand. Section 29 of the Act explicitly prohibits the sale of alcoholic drinks to any person under the age of 20. This provision clearly establishes the Thai drinking age as 20 years old. The statute applies universally—Thais and foreigners alike must comply with this legal threshold.
The purpose of the Act was to unify existing laws under a public health paradigm. By establishing clear boundaries on age, time of sale, place of consumption, and advertisement, the Thai government sought to reduce alcohol-related harm and promote responsible consumption.
Section 42 of the Act provides penalties for violations of age-related sales restrictions. Retailers found selling alcohol to underage persons may face fines of up to 20,000 Baht and imprisonment for up to six months. These penalties may be compounded for repeat violations or where the seller failed to verify the buyer’s age. Businesses may also risk suspension or revocation of their licenses under the authority of provincial governors or the Alcohol Control Committee.
The law also provides enforcement powers to officials from the Ministry of Public Health, who are authorized to conduct surprise inspections and initiate criminal proceedings. However, despite these powers, practical enforcement has remained inconsistent across the Kingdom, especially in high-tourism zones like Bangkok, Pattaya, and Phuket.
A critical point for foreign nationals to understand is that the Thai drinking age applies uniformly, regardless of the laws in their home countries. For example, a 19-year-old tourist from Germany or the United Kingdom may be legally permitted to drink in their country of origin but is prohibited from purchasing or consuming alcohol in Thailand. Violation of this law may result in fines, deportation, or criminal charges.
This strict interpretation underscores the principle of territoriality enshrined in Section 4 of the Thai Penal Code, which affirms that any offense committed within the Kingdom is subject to Thai law, irrespective of the nationality of the perpetrator.
Thailand’s drinking age and international legal standards
- Convention on the Rights of the Child and Thai compliance
Thailand is a State Party to the Convention on the Rights of the Child (CRC), which mandates the protection of individuals under 18 from substances that may harm their health. Article 33 of the CRC obliges Thailand to prevent the use of minors in the illicit production and trafficking of alcohol.
In alignment with the CRC, the Thai drinking age of 20 exceeds the international minimum standard of 18. This reflects Thailand’s preventive approach and its intention to comply not only formally but also substantively with global norms.
- Impact of ASEAN harmonization and WHO recommendations
The World Health Organization (WHO) recommends a minimum drinking age of 18. Thailand’s higher threshold positions it as a regional leader in alcohol regulation. However, as ASEAN integration deepens, pressure may rise to harmonize national regulations.
Still, Thailand has defended its policy on the grounds of public health, especially given the high incidence of alcohol-related traffic accidents. According to the Department of Disease Control, 34% of fatal road accidents during the 2024 New Year holiday were linked to alcohol use.

The restrictions and prohibitions under Thailand’s drinking age laws
Sale restrictions under Thailand’s drinking age laws
Section 28 of the 2008 Act sets strict limits on when alcohol may be sold. Currently, sales are permitted only from 11:00 to 14:00 and from 17:00 to 00:00. Exceptions exist for licensed entertainment venues. These restrictions apply in conjunction with the Thai drinking age. Therefore, even if a person is legally of age, they may not purchase alcohol outside of permitted hours.
Further, alcohol cannot be sold in certain zones, including temples, schools, public parks, and petrol stations. These bans are enforced regardless of the consumer’s age and are grounded in the principle of public morality and youth protection.
Prohibition of alcohol advertisement targeting minors under Thailand’s drinking age laws
Section 32 of the Act prohibits advertisements that encourage alcohol consumption or depict drinking in a positive light. The purpose is to prevent youth from associating alcohol with success, popularity, or social status. As part of this policy, all alcohol advertisements must include warning messages about health risks. Violations are punishable by imprisonment of up to one year and/or fines of up to 500,000 Baht.
The regulation indirectly supports the enforcement of the Thai drinking age by limiting commercial influences that may target underage individuals, particularly through online and social media platforms.
The proposed legal reform of 2025: toward stricter age enforcement
Submission of a new alcohol control bill to Parliament
In January 2025, the Ministry of Public Health submitted a new Alcohol Control Bill to the Thai Parliament. The bill represents a significant policy shift aimed at enhancing the enforcement of existing age restrictions and expanding regulatory tools.
One of the primary goals of the proposed legislation is to close enforcement gaps. Although the Thai drinking age has remained fixed at 20 years, underage consumption persists, particularly in urban nightlife districts. To combat this, the bill proposes the creation of provincial alcohol control committees empowered to monitor local compliance, conduct inspections, and recommend sanctions.
Stricter measures to prevent underage drinking
The new bill introduces stricter verification requirements for alcohol sales. Vendors will be legally obliged to request official identification before completing any transaction. Failure to comply will expose them to heavier sanctions, including license suspension.
Moreover, the bill seeks to strengthen accountability by holding not only vendors but also producers and event organizers liable for alcohol-related incidents involving underage individuals. This includes music festivals, promotional events, and nightlife establishments.
Revising permitted hours of alcohol sales
Another notable reform proposed in the 2025 bill is the revision of permitted sales hours. While the Thai drinking age remains unchanged, the afternoon ban on sales between 14:00 and 17:00 is under reconsideration. The bill aims to align sales hours with international standards while ensuring that underage access remains restricted.
The proposed adjustment would provide a clearer and more practical framework for businesses, particularly those serving international clientele, without compromising youth protection policies.
Alcohol-related liabilities and traffic law enforcement
Thailand’s drinking age and drunk driving-related regulations
Under Thai law, the consumption of alcohol by minors is not only prohibited in itself but may also trigger secondary liability when combined with other offenses such as drunk driving. The Land Traffic Act B.E. 2522 (1979) imposes strict penalties for driving under the influence.
If an underage individual is found operating a motor vehicle while intoxicated, both criminal and administrative sanctions apply. These may include license revocation, fines, imprisonment, and mandatory rehabilitation programs. Courts often impose additional penalties on adults who supplied alcohol to such minors.
Legal consequences for adults enabling underage drinking
The 2008 Act contains no safe harbor for adults who enable or overlook underage drinking. A parent, teacher, or event host who provides alcohol to a minor may be prosecuted under Section 31 and related Penal Code provisions. The law treats this conduct as aggravating, especially when it results in harm.
The 2025 bill reinforces this principle by expanding the scope of liability to include negligence-based offenses, thereby promoting a culture of proactive compliance.
Conclusion
The Thai drinking age, legally set at 20 years, remains a core element of Thailand’s alcohol regulation framework. Codified under the Alcoholic Beverage Control Act B.E. 2551 (2008), the age limit is uniformly applied to all individuals within the Kingdom, regardless of nationality. The law imposes criminal liability for violations and empowers regulatory authorities to conduct inspections and impose penalties.
Despite these protections, challenges in enforcement—particularly in nightlife and tourism districts—have necessitated reform. The 2025 Alcohol Control Bill, currently under parliamentary review, proposes significant enhancements to the legal regime. These include stricter verification requirements, broader liability rules, and refined sale-hour regulations. Importantly, the bill reinforces the existing Thai drinking age while targeting systemic loopholes.
Benoit & Partners advises all businesses operating in Thailand, especially those in the hospitality, retail, and entertainment sectors, to ensure full compliance with the Thai drinking age and all related laws. Given the growing scrutiny and the potential for criminal liability, proactive legal due diligence is essential.
