What happens if you smoke in a Vegas hotel room?

Smoking is limited to tobacco, so be sure to follow those rules as well. As for rooms, certain rooms and suites permit smoking. Be aware: Any guest caught smoking in a strictly non-smoking hotel room an incur fees if caught doing so. Ask for a smoking room specifically, if you plan to do so.



If you smoke (or vape) in a non-smoking Las Vegas hotel room in 2026, the consequences are swift and expensive. Nearly all major resorts on the Strip—including MGM and Caesars properties—now use advanced air-quality sensors (like FreshAir or Wynd) that detect tobacco and cannabis smoke in real-time. Once detected, the hotel will automatically assess a "Deep Cleaning Fee" to your bill, which in 2026 typically ranges from $300 to $500 per night of violation. Beyond the financial penalty, you may be asked to leave the hotel without a refund for violating the terms of service. Since the Nevada Clean Indoor Air Act is strictly enforced, smoking is also a misdemeanor in many indoor public areas. A supportive peer tip: if you need to smoke, head to the casino floor (where it is still permitted in most properties) or a designated outdoor smoking lounge to avoid a massive surprise on your checkout bill.
