Cruising is a popular vacation choice, offering relaxation, entertainment, and a chance to visit multiple destinations.
But as marijuana legalization continues to expand in the U.S. and other countries, many travelers are wondering: what are the policies for smoking marijuana on a cruise?
Whether you’re planning to bring cannabis onboard or considering its use during shore excursions, understanding the rules is essential.
Let’s break it all down in detail so you can avoid any unpleasant surprises during your trip.
The Basics of Cruise Marijuana Rules
Marijuana laws are complex, and they can vary significantly between countries, states, and even local jurisdictions.
For cruise ships, the rules become even stricter.
Most cruise lines strictly prohibit cannabis, even if it’s for medical use or purchased legally at your port of embarkation.
This is due to a combination of federal laws, international maritime regulations, and the cruise industry’s focus on maintaining a safe environment onboard.
Here’s why cruise marijuana rules are so rigid:
- Federal Laws Dominate at Sea: While some states in the U.S. have legalized marijuana, cruise ships sailing from U.S. ports are governed by federal law.
Under federal regulations, marijuana is still classified as a Schedule I controlled substance, meaning its possession and use are illegal.
Even a small amount of cannabis can lead to legal consequences if discovered onboard.
- International Waters and Port Regulations: Cruise ships often sail through international waters and visit countries with varying cannabis laws.
What might be legal in one location can result in severe penalties in another.
For example, possession of marijuana in some countries could lead to immediate arrest or hefty fines.
- Company Policy: Cruise lines aim to maintain a family-friendly atmosphere and avoid legal entanglements that could arise from differing laws at their ports of call.
Therefore, they often implement blanket bans on marijuana to ensure compliance across all regions.
In short, most cruise lines adhere to a zero-tolerance policy for marijuana onboard, regardless of where you embark or disembark.

Cruise Line-Specific Policies
Different cruise lines have varying approaches to enforcing marijuana policies, but the message is generally the same: no cannabis onboard.
Here are a few examples that highlight the stance of major cruise operators:
1. Carnival Cruise Line
Carnival Cruise Line’s policy explicitly bans marijuana in any form, including medical marijuana and cannabis-derived products like edibles, oils, or tinctures.
Their drug policy emphasizes that federal laws apply onboard, and any violations may result in fines, disembarkation, or even legal action.
Security screenings at embarkation are thorough, and passengers should not expect leniency.
2. Royal Caribbean International
Royal Caribbean takes a similarly strict stance.
The cruise line’s guest policy prohibits any drugs or substances considered illegal under federal, state, or international law.
Passengers caught with marijuana risk being removed from the ship at the next port, regardless of whether it’s legal at the port of embarkation or disembarkation.
Royal Caribbean also explicitly mentions that medical marijuana is not allowed, even with proper documentation.
3. Norwegian Cruise Line (NCL)
Norwegian’s rules are no different. Marijuana, including medical cannabis and CBD products, is strictly prohibited on their ships.
The cruise line has stated that passengers found violating this policy will face immediate consequences, including disembarkation.
This applies to both recreational and medicinal use, as Norwegian prioritizes compliance with federal and international laws.
4. Celebrity Cruises
Celebrity Cruises adheres to a zero-tolerance policy for drugs, including marijuana.
Even if you’re traveling with a valid medical marijuana card, the cruise line does not allow cannabis onboard.
Security personnel are trained to detect cannabis in luggage, and any violations will lead to penalties.

Even CBD products that are marketed as non-psychoactive are not allowed onboard.
Shore Excursions: Can You Use Marijuana in Port?
What about using marijuana during shore excursions?
The answer depends on the laws of the port you’re visiting.
Here are some general guidelines to keep in mind:
- Legal in Port Doesn’t Mean Legal on the Ship: Even if a cruise stops in a port where marijuana is legal, such as in Canada or certain U.S. states, you cannot bring cannabis back onboard.
Security teams conduct thorough checks when passengers return to the ship, and any cannabis products will be confiscated immediately.
- Be Aware of Local Laws: While some destinations, like Amsterdam or Jamaica, have more relaxed marijuana laws, others have severe penalties for possession.
Always research local regulations before using cannabis during a shore excursion.
Some countries, especially in the Caribbean and Asia, impose harsh penalties for marijuana use, including imprisonment.
- Risks of Missing the Ship: If you consume marijuana in port and fail to return on time due to legal issues or other complications, the ship will not wait.
Passengers are responsible for their own actions ashore, and missing the ship can be a costly mistake.
Shore excursions provide an opportunity to enjoy unique local cultures, but understanding the legal landscape is critical for avoiding unnecessary trouble.

Medical Marijuana and Cruises
For travelers with a medical marijuana prescription, cruising presents unique challenges.
While you may rely on cannabis for health reasons, cruise lines do not allow exceptions for medical use.
Here’s what you can do if you’re in this situation:
- Consult Your Doctor: Speak with your healthcare provider about alternatives to medical marijuana that you can bring onboard.
Non-cannabis options such as FDA-approved medications or therapeutic treatments may be a suitable substitute.
- Pack FDA-Approved Medications: Prescription pills, transdermal patches, or other approved treatments that comply with cruise policies can help manage medical conditions without violating onboard rules.
- Notify the Cruise Line: If you have specific medical needs, inform the cruise line before departure to discuss available accommodations.
They may be able to provide resources or suggestions tailored to your situation.
It’s important to prepare in advance to avoid disruptions to your travel plans.
CBD Products: Are They Allowed?
The rules around CBD (cannabidiol) products vary by cruise line.
While some passengers assume that non-psychoactive CBD oil or creams are acceptable, most cruise companies prohibit them due to the lack of regulation and potential THC content.
It’s best to leave all CBD products at home to avoid complications at security checkpoints.
Passengers attempting to bring CBD onboard may have these items confiscated, and repeated violations could result in removal from the ship.
What Happens If You’re Caught with Marijuana on a Cruise?
If you’re caught with marijuana onboard, the consequences can be severe, including:
- Confiscation of the Substance: Security will seize any marijuana found during bag checks or onboard inspections.
- Removal from the Ship: Passengers caught violating the drug policy may be disembarked at the next port, with no refunds or compensation.
This can leave travelers stranded in unfamiliar locations, often at their own expense.
- Legal Action: Depending on the situation and jurisdiction, you could face fines, arrest, or prosecution.
This applies even if marijuana is legal in your home state or country.
Cruise lines take their drug policies seriously to comply with international laws and ensure the safety of all passengers.
Violating these rules can result in significant legal and financial repercussions.
