Public Conduct

  • Smoking is banned in enclosed public spaces and workplaces nationwide; most pubs and bars enforce outdoor-only smoking areas.

Medicines You Can't Bring

  • Some strong prescription painkillers and ADHD medications are controlled drugs under UK law; bring the original prescription and, for larger supplies, consider a doctor's letter confirming it's for personal use.

Photography & Drones

  • Photography is generally permitted at most tourist sites, though museums, galleries, and some private venues set their own restrictions. Drones must be registered with the Civil Aviation Authority if they weigh 250g or more, and flying near airports or over crowds is restricted.

Drugs & Alcohol

  • The legal drinking age is 18 across England, Wales, Scotland, and Northern Ireland, no exceptions for tourists.
  • Possession of recreational drugs is illegal; penalties can include up to 7 years in prison and/or a fine, even for drugs that are legal or decriminalized in parts of the U.S.

Carrying ID

  • There's no general legal requirement to carry ID in the UK, but you'll need photo ID with a hologram or UV feature (a passport works) to buy alcohol if you look under 25.

The Gotcha

The UK is one of the more relaxed countries on this page about carrying ID day-to-day, there's no 'stopped and asked to produce it' law the way there is in much of continental Europe or Japan, but that relaxed approach doesn't extend to drug penalties, which are genuinely serious (up to 7 years) for substances that carry little to no consequence in parts of the U.S.
