Smoking is still relatively common in Greece, but you should not assume it is acceptable everywhere: many indoor public places, offices, and transport areas are officially smoke-free, and you should always look for a designated smoking section or ask before lighting up. In practice, enforcement can be uneven and you may see people smoking in cafés or bars, especially in more casual settings, but it is polite to follow the venue’s rules and avoid smoking around families, children, or in crowded enclosed spaces.
