As the world becomes more accepting of cannabis use, both for medical and recreational purposes, the question of international travel with cannabis arises. Despite the increasing legalization of marijuana use at the state level, it remains a federally illegal, Schedule I–controlled substance under the Controlled Substances Act [1].

This article aims to provide a comprehensive guide on the legal restrictions around traveling with cannabis, with a particular focus on the U.S.-Canada border.

The Canada-U.S. Border: A Reminder from CBSA

The Canada Border Services Agency (CBSA) has issued a stern reminder to travelers: no cannabis across the border [2]. This reminder is particularly relevant for those planning to traverse the border between the U.S. and Canada. Despite the legalization of cannabis in both countries, the international border remains a cannabis-free zone.

Cannabis: Don't Bring It In. Don't Take It Out.

This is the clear message from CBSA. The restrictions on cannabis being brought across the border are firm and non-negotiable. Regardless of the legal status of cannabis in your home country or destination, the border is not a place for it.

The High Times Guide to Flying with Marijuana

Traveling domestically with cannabis is a different story. Within the U.S., for instance, a short domestic flight does not involve customs, making it easier to travel with cannabis [3]. However, it's essential to be aware of the laws and regulations in both your departure and arrival states.

The Cannabis Landscape: A Global Perspective

The cannabis conversation is not limited to North America. Europe is grappling with the growing trend of Delta-8 cannabis products [4], and countries like Afghanistan have a legendary hash scene that transcends political history [5].

Cannabis Distillates: The Future of Legal Pot?

The distillation process has been modified to become part of cannabis concentrate development, representing the potential future of legal pot [6].

Canada - US Border

Can I Bring Weed out of Canada?

Since Canada legalized cannabis for adults in 2018, many people have wondered about the legality of bringing weed out of Canada [7]. The answer is a resounding no. Despite the legalization within the country, international borders remain off-limits for cannabis.

Cannabis Legislation Around The World

Countries around the world are paying attention to Canada's cannabis experiment. Some are looking to Canada for guidance or lessons, while others criticize it for flouting international anti-drug treaties [8].

Warnings to Citizens: Don't Smoke Weed in Canada

Some countries are warning their citizens not to smoke weed in Canada, despite its legal status there. The legal implications of consuming legal cannabis in Canada can still be a criminal liability back home.

Navigating the Complexities of Traveling with Cannabis

In the wake of increasing legalization of cannabis use across various states and countries, a significant question arises: What are the legal restrictions around traveling with cannabis?

Despite the growing acceptance of marijuana use at the state level, it remains a federally illegal, Schedule I–controlled substance under the Controlled Substances Act[1]. This conflict between federal and state laws necessitates a clear understanding of the rules and regulations when traveling with cannabis.

Domestic Travel with Cannabis

Traveling domestically with cannabis can be a relatively straightforward process, provided you are aware of the specific laws in both your departure and arrival states. For instance, a short domestic flight from San Francisco to Portland does not involve customs, making the process easier[3]. However, it is essential to check the specific cannabis laws in both states to ensure compliance.

Checking Departure and Arrival State Laws

Before embarking on your journey, it is crucial to research and understand the cannabis laws in both your departure and arrival states. This information can usually be found on the respective state government's website or through resources such as the High Times Guide to Traveling With Pot[1].

International Travel with Cannabis

When it comes to international travel, the rules become more complex. The Canada Border Services Agency (CBSA) recently released a press release reminding travelers that bringing cannabis across an international border is illegal[2]. This applies even if cannabis is legal in both the departure and arrival countries.

Canada-US Border: No Cannabis

For those planning to cross the border between the U.S. and Canada, it is important to note that the CBSA strictly prohibits the transportation of cannabis across the border. This rule applies regardless of the legality of cannabis in both countries[2].

Other International Borders: Check Specific Laws

Different countries have varying laws regarding cannabis. Some countries, like Uruguay, have legalized marijuana, while others, like Russia, have stringent anti-drug treaties in place[8]. Before traveling internationally with cannabis, it is crucial to check the specific laws of the countries you are traveling to and from.

The Future of Traveling with Cannabis

As the cannabis industry continues to evolve, so too will the laws and regulations surrounding traveling with cannabis. New compounds in cannabis, such as Delta-8, are gaining popularity and may influence future legislation.

Evolution of Cannabis Laws

Evolution of Cannabis Laws

The laws surrounding cannabis have evolved significantly over the years. In the 20th century, the Cannabis Tax Act of 1937 and the Controlled Substances Act of 1970 marked significant milestones in the regulation of cannabis.

The 21st century saw further changes, with Colorado and Washington legalizing recreational cannabis in 2012 and Canada following suit in 2018. As of 2023, we are witnessing the current laws and regulations that govern the use and transportation of cannabis.


Traveling with cannabis, whether domestically or internationally, requires a thorough understanding of the laws and regulations in place. While the landscape is continually evolving, the current rules necessitate caution and research before traveling with cannabis. As the industry continues to grow and new compounds emerge, we can expect further changes to these laws and regulations.

Remember, when it comes to traveling with cannabis, the golden rule is to always check the laws of your departure and arrival locations. Stay informed, stay safe, and enjoy your travels.
