When visiting Thailand, it is important for tourists to respect the local traditions and laws to ensure their safety and have a smooth travel experience.

Important prohibitions in Thailand:

• Disrespecting the Royal Family and Monarchy: It is illegal and highly disrespectful to show any disrespect towards the King, Queen, and the Royal Family. Avoid any actions that could be considered offensive or harmful.
• Inappropriate behavior at sacred sites: Dress modestly when visiting temples (such as Wat Arun). Avoid making loud noises and refrain from engaging in impolite behavior during your visit.
• No touching of monks: According to Thai customs, monks should not be touched by women in any manner.
• Public displays of affection: Avoid public displays of affection, nudity, or any behavior that is overtly sexual.
• Drugs: Possession of narcotics carries severe penalties. Cannabis flower and products above 0.2% THC are restricted to medical use with a valid Thai prescription (PT 33) since mid-2025; recreational use and public smoking are not permitted. Do not take cannabis out of Thailand.
• Vaping: Import and sale of e-cigarettes and vape liquid are prohibited; travelers have been fined at customs.
• Theft: Stealing someone else’s property is illegal and unethical.
• Physical Assault: Causing physical harm to others is prohibited by law.

Rules to Be cautious about:

• Driving Rules: Always wear a helmet while riding a motorcycle. Follow traffic signals and refrain from driving under the influence of alcohol.
• Smoking Regulations: Refrain from smoking in public areas. Use designated smoking zones. Some public places, like malls, strictly enforce no-smoking policies.
• Pet Etiquette: Avoid bringing pets into certain public places, such as temples and restaurants.
• Price Negotiation: Bargaining is common in Thailand, but always do it politely.

Additional Recommendations:

• Thais often remove their shoes before entering homes.
• The head is considered the highest part of the body; avoid touching or passing objects over someone’s head.
• Feet are considered low; avoid pointing them at people or stepping over people or things.
• Thais don’t usually drink tap water at home or outside, even though the government says it’s safe to drink. They only drink from fountains in places like malls or airports.
• Walking without a shirt in public is considered inappropriate.
