Drugs, alcohol and travel

Find information and advice to help you understand and avoid the risks related to travelling with drugs and alcohol.

Cannabis

It is illegal to take cannabis – including products containing cannabis, such as edible cannabis, cannabis extracts and cannabis topicals, and all products containing CBD – across the Canadian border, whether you are entering or leaving the country:

No matter how much cannabis you have with you.
Even if you use cannabis for medical purposes in any form, including cannabidiol (CBD), unless authorized by Health Canada.
Even if you are travelling to or from a municipality, state or country where cannabis has been legalized or decriminalized.

At your destination

If you travel to other countries, including the United States, with any amount of cannabis in your possession, you could:

be charged with a criminal offence (This applies to all countries, whether cannabis is legal there or not.)
be denied entry at your destination if you have previously used cannabis or any substance prohibited by local laws
be denied entry to other countries in the future

It is your responsibility to learn about the laws, including the legal status of cannabis use and possession, in your destination country.

If you are travelling for business related to the cannabis industry, contact the foreign government office in Canada of the country you plan to visit.

For more information, consult our Travel Advice and Advisories.

Returning to Canada

It is illegal to enter Canada with cannabis, unless you have a prescription for a medication containing cannabis authorized by Health Canada.

If you are entering Canada and have cannabis with you in any form, you must declare it to the Canada Border Services Agency.

Not declaring cannabis in your possession at the Canadian border is a serious criminal offence. You could be arrested and prosecuted.

Illegal drugs

Do not agree to transport, hold, buy or use illegal drugs under any circumstances.

When you are abroad, you are subject to the laws of the country you are visiting.

Most countries, including the United States, have a zero-tolerance policy with respect to illegal drugs, including possession and use. You could face severe penalties for the possession of even a small quantity.

You may also be denied entry to a country if you have previously used drugs that are considered to be illegal in that country.

Being a foreigner or not knowing the local laws is no excuse to be carrying illegal drugs. Your Canadian citizenship does not give you immunity or preferential treatment in other countries.

In Canada and abroad, be aware that illegal drugs may be mixed with other more potent substances that can lead to health harms including overdose and death. You may not be buying what you expected.

Drug trafficking

Follow these simple precautions to help avoid unintentional import or export of controlled substances:

Pack your luggage yourself, keep it securely closed and keep an eye on it.
Never carry a gift, package or luggage for anyone across a border or through customs unless you are sure of its contents. If drugs are found, you will be held responsible.
Never pick up hitchhikers or cross an international border with someone you don't know or trust.

Crossing the border with controlled substances

It is illegal to take controlled substances across the Canadian border, whether you are entering or leaving the country, unless you have a prescription to do so.

Refer to the exemption for travellers for more information on importing or exporting prescription drug products containing a narcotic or a controlled drug.

You must always declare your prescription medication with a controlled substance to a customs officer at the point of entry into Canada at the time of import. In the case of an export, the export must not contravene the laws and regulations of the country of destination.

Remember that there are limits to the amount of prescription drugs you can carry with you when you travel – particularly when they contain controlled substances or cannabis.

Learn more about travelling with medication.

If you attempt to cross a border with controlled substances without authorization, you could:

be charged with a serious criminal offence
be denied entry at your destination
be denied entry to other countries in the future

Exemption in British Columbia and what it means for travellers

From January 31, 2023 to January 31, 2026, adults (18 and over) in the Canadian province of British Columbia will not be subject to criminal charges for the possession of a cumulative total of up to 2.5 grams of certain illegal drugs for personal use, subject to certain exceptions.

This exemption does not change Canada's border rules. Taking illegal drugs across the Canadian border – either exiting or entering – remains illegal even if travelling to and from BC, where an exemption will be in place. It can result in serious criminal penalties both in Canada and abroad.

Alcohol

The import, possession and use of alcohol are strictly prohibited in some countries.

Before travelling outside Canada, contact the foreign government office in Canada of the country you plan to visit to find out whether alcohol is permitted.

See the list of foreign representatives in Canada.

If you plan on bringing alcohol back to Canada, remember that you’ll need to declare it at the border and that there are limits on quantities you can bring in.

Drinking alcohol

You should follow the same safety rules for drinking abroad that you would at home.

Follow these tips to stay safe:

If you choose to drink alcohol, follow the guidance provided by the Low-Risk Alcohol Drinking Guidelines.
Be aware of the source of your drink.
- If obtained from an unregulated source, it could be mixed with other unknown substances that could lead to health harms.
- Never accept drinks from strangers.
- Never leave your drink unattended.
Watch your drinks as they are being prepared and served.
- They may be laced with hypnotic drugs that could put you at risk of robbery or sexual assault.
The alcohol available at your destination may be much stronger than you are used to.
- Do not drink home-brewed alcohol.
Keep in mind that some places may not tolerate excessive drinking or any drinking at all.
Never drink in countries where it is prohibited.
Do not drink or use drugs and drive or get into a vehicle with someone who has.
- You could cause harm to yourself or others and face severe penalties.

If you’re arrested

Canadian consular services officials can provide some assistance, but they cannot override the decisions of local authorities and they cannot arrange for your release.

If you run into trouble abroad, let the arresting authorities know right away that you want to notify Canadian consular officials.

Local authorities do not have to notify the Canadian consular or diplomatic office of your arrest unless you specifically ask them to do so.
