Public Conduct

  • Consuming alcohol in public places like streets and parks is generally prohibited outside of authorized events.

Medicines You Can't Bring

  • Bring medications in original, labeled packaging with your prescription; some stimulant and opioid-based medications require prior documentation for larger supplies.

Photography & Drones

  • Drones require registration with Portugal's civil aviation authority (ANAC) above certain weight thresholds, and flying in Lisbon and Porto's historic centers is restricted.

Drugs & Alcohol

  • The legal drinking age is 18, strictly enforced with ID checks.
  • Portugal decriminalized personal possession of all drugs (not just cannabis) in 2001: possessing up to roughly a 10-day personal supply is an administrative matter (referred to a panel that can recommend treatment, fines, or warnings), not a criminal one. Selling and trafficking remain serious criminal offenses.

Carrying ID

  • Carry ID if you plan to purchase alcohol; bars and stores strictly enforce age verification.

The Gotcha

Portugal's drug decriminalization is genuinely famous, but it's easy to over-read: it applies to personal-use quantities and treats possession as an administrative matter, not that drugs are legal. Selling, trafficking, or possessing beyond the personal-supply threshold is still a real criminal matter, and being a foreign tourist doesn't change how the administrative process treats you.
