From legal highs to tighter rules: Thailand rethinks weed rules after tourist boom

As with any travel destination, picking up a few simple phrases such as “sawasdee ka/krap” (hello, for women/men) and "khob khun" (thank you) can make a big difference. Locals are usually grateful for the effort, even if your pronunciation isn’t spot on.

Although Thailand’s beaches have a laid-back vibe, the country’s culture is generally conservative. When venturing away from the coast—especially to temples and religious sites—it's important to dress respectfully. These temples are not just tourist spots; they are sacred places of worship. Make sure to cover your shoulders and knees, and if you're a woman, it's a good idea to carry a scarf or sarong for extra coverage.

Credit cards are typically accepted only at bigger businesses, and even then, a 3% fee is often added. It’s a good idea to carry cash, particularly in smaller denominations. While tipping isn’t required, it’s a thoughtful gesture—especially at restaurants and spas. Leaving some loose change or rounding up the bill with small notes is usually appreciated.

Bargaining is a normal part of shopping in Thailand’s vibrant markets. If you're purchasing several items from the same stall, it’s fine to ask for a small discount—but do so politely and with a smile. Keep the exchange friendly and avoid being pushy. It’s important to remember that your currency probably stretches further here, and many sellers are running small, family-owned businesses. Thai people are known for their namjai—a generous and kind spirit—and are often willing to offer a fair deal when haggling is approached with respect and good intentions.

In Thailand, it’s traditional to remove your shoes before stepping into homes, temples, massage centers, and even certain cafés or stores. Walking in with shoes on—especially in a home—can cause visible discomfort. When unsure, just glance down: if you see a line of shoes at the entrance, that’s your sign to take yours off and leave them there too.

In Thailand, eating is more than just a necessity—it’s a beloved part of daily life. In fact, the common greeting “Have you eaten?” reflects just how central food is to the culture, much like saying “How are you?” elsewhere. While solo dining is increasingly common in Thailand’s fast-paced cities, meals are traditionally enjoyed together. To truly eat like a local, order a variety of dishes to share, all served family-style with a pot of rice.

Thailand’s street food scene is iconic, offering an incredible variety of dishes at every turn. When choosing where to eat, follow the locals’ lead. Don’t rely too heavily on menu descriptions—they can sometimes be confusing or mistranslated. Instead, pay attention to what you see and smell. Does the food look good? Does it smell fresh? Are local people lining up? Crowded stalls usually mean the food is fresh and in demand. Stick to cooked items, and be cautious with raw foods unless you’re familiar with the vendor.

Thailand is a constitutional monarchy, and it’s important to be aware that lèse-majesté laws strictly prohibit any disrespect toward the royal family. Making jokes or negative remarks about the monarchy isn’t just culturally offensive—it can also lead to legal consequences. Always show respect toward images of the king, the royal family, and religious figures like the Buddha.

It’s rare to hear a Thai person raise their voice. Even when feeling uneasy, upset, or sad, many Thais respond with a smile. The culture values calm and composed behavior, so people generally speak softly and steer clear of showing anger in public. Yelling, honking, or visibly losing your temper is seen as "losing face," which is considered inappropriate. Even during hectic traffic or rush hour, honking is uncommon. Instead, embrace the relaxed Thai mindset known as sabai-sabai—a reminder to stay calm and easygoing.​
