Know Before You Go: Mexico
The laws, local rules, safety tips, and cultural things I’d want to know before landing
Mexico is one of those places where travelers can get into trouble by assuming the rules are basically the same as back home.
They are not.
And because you already have Mexico City, Puerto Vallarta, Cancún, and Cabo, I would make this one strong Mexico-wide page and link to it from all four itineraries.
Cannabis Is Not “Basically Legal”
This is one I would be very clear about.
Mexico has gone through major legal changes around personal cannabis use, but that does not mean tourists should treat it like California.
U.S. travel guidance still warns that importing drugs, including medical marijuana, is illegal, and drug possession can lead to serious legal consequences.
My rule?
Do not bring weed into Mexico just because it is legal where you live.
Leave the Vape at Home
This one surprises people.
Mexico prohibits bringing e-cigarettes and vaping devices into the country, and customs can confiscate them or create problems at entry.
If you vape at home, do not assume you can throw it in your carry-on and deal with it later.
Do Not Bring Weapons or Ammunition
This includes things travelers may forget are sitting in a bag or car.
Mexican law is strict about firearms and ammunition, and U.S. permits do not carry over into Mexico. Even ammunition or used cartridges can cause serious legal trouble.
Check your bags before the trip.
Seriously.
Be Careful With “Fines” on the Road
If someone claiming to be police asks you for cash on the spot:
Stay calm
Ask what the violation is
Ask for identification if it feels safe
Ask whether the fine can be handled through an official process
Do not start flashing how much cash you have
Prioritize getting out of the situation safely
And do not flee a checkpoint. U.S. guidance specifically warns travelers to cooperate at checkpoints and avoid behavior that could look aggressive.
Drinking Age Is 18
The legal drinking age in Mexico is 18.
That said, I would still be careful about where drinks are coming from, especially in heavy nightlife areas.
Do Not Assume Every “Official Fee” Is Cash
Mexico’s immigration authority states that official immigration-related payments are handled electronically or through banks, not as cash payments handed directly to immigration personnel.
If something feels unofficial, slow down and verify it.
💡 SHANE’S TIP
Mexico is not a place where I would travel paranoid.
But I would travel informed.
Know what you are bringing into the country, keep your documents accessible, and if something involving police, customs, or money feels off, do not let panic make the decision for you.
