Thailand is a top travel destination known for its stunning beaches, rich culture, and legendary hospitality. But if you’re visiting from neighboring countries or other parts of Asia, you might be surprised to learn that some everyday habits or freedoms elsewhere could get you into serious legal trouble here. Whether you’re a tourist or a new expat, understanding the laws is key to staying safe and respectful.
Here are five things that are illegal in Thailand—but often legal or tolerated in other Asian nations.
1. Vaping (E-Cigarettes)
Status in Thailand: Completely illegal to import, sell, or use.
Despite the global trend toward vaping as a smoking alternative, Thailand takes a hard stance. Anyone caught using or possessing e-cigarettes can face fines up to THB 30,000 or even jail time. There have been reports of tourists detained for having vapes, so it’s not something to take lightly.
Legal in: Japan, South Korea, and the Philippines.
Travel Tip: If you vape, leave your device at home when visiting Thailand.
2. Public Criticism of the Monarchy (Lèse Majesté)
Status in Thailand: Strictly illegal under Section 112 of the Thai Criminal Code.
Thailand has some of the world’s strictest lèse majesté laws. Any public criticism of the monarchy—whether spoken, written, or posted online—can lead to 3 to 15 years in prison per offense. This law applies to both Thais and foreigners.
Legal or loosely restricted in: Japan, Taiwan, Indonesia.
Travel Tip: Always show respect when discussing the royal family.
3. Recreational Cannabis Use in Public
Status in Thailand: Illegal in public spaces—even though cannabis is now regulated for medicinal and private use.
Thailand made headlines in 2022 for decriminalizing cannabis, but this doesn’t mean you can light up anywhere. Using cannabis in public is still punishable under public nuisance laws, which can include fines and jail time.
Travel Tip: Use cannabis only in private, legal venues and avoid public consumption altogether.
4. Gambling (Casinos & Sports Betting)
Status in Thailand: Mostly illegal.
With few exceptions (like the state lottery and horse racing), gambling is banned in Thailand. That includes casinos, sports betting, and online gambling platforms. Getting caught can result in fines or imprisonment.
Legal in: Macau, Singapore, and the Philippines.
Travel Tip: Don’t be tempted by underground gambling venues—they’re illegal and often linked to scams or organized crime.
5. Magic Mushrooms & Psychedelics
Status in Thailand: Classified as illegal narcotics.
Although magic mushrooms are sometimes offered in tourist areas, they remain illegal. Possession or use can result in serious criminal charges. Thai drug laws are strictly enforced, and the consequences can be severe.
Tolerated in: Some areas of Cambodia and Indonesia (e.g., Gili Islands).
Travel Tip: Steer clear, even if it seems locally accepted. The risks far outweigh the experience.
Thailand’s laws reflect its cultural values, history, and social norms. What might be accepted—or even celebrated—elsewhere can carry heavy penalties here. If you’re visiting or living in Thailand, it pays to stay informed and respectful of local regulations.
By understanding and honoring the law, you’ll not only protect yourself but also help foster positive cross-cultural connections.
