Tourist areas may charge slightly more, so it’s wise to compare options. If you’re staying longer, some dispensaries offer bulk discounts.
Can You Smoke Weed on the Beach?
While Koh Samui’s beaches are stunning, discretion is essential. Public smoking may not always be socially acceptable, especially near families or busy areas. Respect local customs and consider private accommodations or designated smoking areas instead.
