No, you are strictly prohibited from bringing CBD gummies, oils, or any other CBD products on a Carnival Cruise. Even if CBD is legal in your home state or the port city of departure, Carnival (and most other major cruise lines) maintains a zero-tolerance policy. This is because cruise ships operate under federal and international maritime laws, and many of the foreign ports the ship visits (such as those in the Bahamas, Mexico, or the Cayman Islands) still classify CBD as an illegal controlled substance. If security finds CBD gummies during the x-ray screening of your luggage or a cabin inspection, they will be confiscated, and you could face serious consequences, including being denied boarding without a refund or being banned from the cruise line for life. In late 2025, Carnival even began deploying drug-sniffing dogs at several terminals specifically to catch prohibited items like marijuana and CBD. For the safety of your vacation, it is best to leave all hemp-derived or cannabis-related products at home.
