In the United States, marijuana possession is illegal under federal law, and airports, being under federal control, do not allow marijuana beyond security checkpoints and in aircraft boarding areas. However, some states that permit marijuana possession may have less restrictive rules in the non-secure areas of the airport. Canada, which allows recreational marijuana use, prohibits it from crossing international borders, including at airports during customs. It is important to consider the potential risks and legal consequences associated with marijuana use in specific jurisdictions when travelling.

Legality of being high at airports in the US and Canada
While US and Canadian laws don't explicitly prohibit passengers from flying under the influence of drugs, airline policies and federal aviation regulations do. Intoxicated passengers have been an ongoing issue on flights, and airlines reserve the right to refuse boarding to anyone who appears to be intoxicated or under the influence of drugs. This is to ensure the safety of all passengers and crew members, as intoxicated passengers may not be able to react appropriately in emergency situations and may pose a hazard.
In the US, marijuana is not allowed in any area under federal jurisdiction, including aircraft and aircraft boarding areas. This means that even in states where marijuana is legal, it is prohibited from being brought onto planes or into federal areas of airports. Some airports may even ban marijuana from all airport property. Additionally, it is illegal to bring marijuana onto a plane when flying into the US, and doing so may result in arrest and prosecution by federal authorities.
In Canada, marijuana is also not allowed to cross any international border, so it is prohibited in any section of the airport where passengers must pass through customs. However, within Canada, the laws regarding marijuana use and possession at airports may vary depending on local laws and regulations.
It is important to note that while being high may be legal in certain jurisdictions, possessing and consuming marijuana at airports and on planes is subject to various laws and regulations. It is always advisable to check the local laws and regulations before travelling with marijuana or consuming it before a flight. Additionally, it is worth considering the potential impact on your health, safety, and the experience of those around you.

Edibles vs smoking weed before a flight
While it is important to be aware of the laws and regulations around marijuana possession and consumption in the US and Canada, individuals may still consider consuming it before a flight. Here is a comparison of edibles versus smoking weed before boarding a flight:
Edibles
Edibles are a discreet way to consume marijuana before a flight. They tend to take effect after a certain digestion time, which may lead to the effects being felt mid-flight. This can be advantageous for those who enjoy listening to music, chatting with fellow passengers, or engaging in an intense in-flight movie. However, it is crucial to be cautious about dosing, especially for inexperienced consumers, to avoid an unpleasant experience at a high altitude. Edibles are easier to transport than smoking weed, as they do not produce smoke or odour.
Smoking Weed
Smoking weed before a flight can provide a different experience compared to edibles. The effects of smoking may start declining shortly after takeoff, making it a suitable option for those who want to relax and pass out during the flight. Smoking weed may be more challenging to consume discreetly, as it involves inhaling and may produce odour. Additionally, it is important to consider the legal implications of smoking weed in public areas, as it may not be permitted in certain jurisdictions.
It is essential to assess your tolerance and experience with cannabis before consuming either edibles or smoking weed before a flight. Cannabis may increase anxiety for some individuals, so it is crucial to understand how it affects you personally. The type of consumption method chosen—edibles or smoking weed—depends on personal preferences and how individuals prefer to experience the effects during the flight.

Tolerance and experience with cannabis
While it is legal to be high at some airports, such as DIA, it is important to consider your tolerance and experience with cannabis before deciding to consume it before boarding a flight.
Tolerance to cannabis refers to the brain's ability to adapt and compensate for the drug-induced disturbance in its functions. The development of tolerance depends on various factors, including the function, species, and dose of cannabis. For instance, "tissue tolerance" and "dispositional tolerance" refer to the brain's ability to adapt to the impairment of functions such as the logical sequence of thoughts and the increased metabolism of delta 9-tetrahydrocannabinol (THC), respectively.
Heavy cannabis users may develop tolerance to the neurocognitive effects of THC, including its impact on memory, attention, and psychomotor performance. However, the development of tolerance can vary between individuals, with some studies reporting conflicting results. Factors such as the frequency and intensity of cannabis use, the age of onset, and the potency of the cannabis product can influence the development of tolerance.
In the context of air travel, it is crucial to consider your tolerance and experience with cannabis before consuming it. Cannabis can have varying effects on individuals, and for some, it may increase anxiety. If you decide to consume cannabis before a flight, it is important to be mindful of the applicable laws and regulations, especially regarding the possession and consumption of cannabis in secure airport areas and on aircraft.
Additionally, the timing of consumption can be important. Edible cannabis products may take longer to produce intoxicating effects, and their impact may peak mid-flight due to digestion time. Smoking cannabis before a flight may result in a high that declines shortly after takeoff. Therefore, it is essential to carefully consider your tolerance and experience with cannabis and make an informed decision based on your understanding of its potential effects.

Airports with amnesty boxes for disposing weed
Although cannabis legalization is spreading across the United States and other countries, it remains illegal in America at the federal level. This means that flying with weed is risky, even if your origin and destination states have legalized it. The secure part of the airport, beyond TSA screening, is under federal control, and marijuana is not allowed in any area under federal jurisdiction, including aircraft and aircraft boarding areas.
Cannabis amnesty boxes are a simple and efficient solution for travelers who want to dispose of cannabis products before their flight. These boxes are typically the size of a garbage can and are vividly colored – often blue or green. A “cannabis amnesty box” sign should be clear and attached to the front side of the can. The seal of the city or state should also be found on the box, confirming the legal nature of the disposal unit.
To date, only a few US airports have installed cannabis amnesty boxes, including Chicago's O'Hare and Midway international airports, and Colorado's Colorado Springs and Aspen airports. Denver International Airport does not have them because marijuana is banned from all airport property.
While local authorities in Chicago have said they aren't arresting passengers caught with pot, federal law still prohibits the transportation of weed across state lines. The amnesty boxes give travelers an easy way to avoid any trouble, although they haven't been widely used.

Airline policies on intoxicated passengers
While being drunk is not a crime, unruly behaviour on a plane is. This includes verbal or physical altercations with crew or passengers, refusing to follow safety instructions, or causing significant disruptions to the flight. Airlines reserve the right to deny boarding to passengers who appear to be excessively intoxicated or disruptive, and passengers can be banned for unruly behaviour. Assaulting a flight attendant or fellow passenger is a federal offence and can result in imprisonment and fines.
In the US, marijuana is not allowed in any area under federal jurisdiction, including aircraft and aircraft boarding areas. If the airport is in a state that allows the possession of marijuana, there may be less restrictive rules in the non-secure area of the airport. However, some airports may choose to ban marijuana from all airport property. In Canada, marijuana is not allowed in any section of the airport where you first have to pass through customs.
Airlines provide training for employees on identifying whether someone is drunk, high, or experiencing a physical condition that could be mistaken for being under the influence. For example, United's contract specifies that passengers could be prohibited from boarding if they are intoxicated or under the influence of drugs, unless they are a "qualified individual whose appearance or involuntary behaviour may make them appear to be intoxicated or under the influence of drugs".
Passengers should also be aware that even if a substance is legal where they are, airlines might deny them boarding if they're intoxicated. Federal aviation regulations state that no airline may allow anyone to board a plane if the passenger appears to be intoxicated, and this includes intoxication from drugs such as marijuana, even in cities or states where they are legal or decriminalised.
