Local laws and customs
Don’t become involved with drugs of any kind. Possession of even small quantities or soft drugs can lead to heavy fines and/or imprisonment. Using or importing khat/qat is prohibited in Iceland.
Smoking in restaurants, bars, public transport and public buildings is prohibited. Anyone caught smoking will be asked to leave the premises and may be fined.
You don’t have to carry your passport with you, but it is sensible to keep some form of ID on you. The British Embassy in Reykjavik deals with a significant - and increasing - number of lost passports by British citizens each year. You should keep your passport somewhere safe at all times and make sure next of kin details are entered into the back of your passport.
Whale products are available in Iceland but tourists should be aware that its importation into the UK or EU is illegal under the Convention on International Trade in Endangered Species. Any importation of whale products to the UK will result in seizure of the goods, possibly a fine of up to £5,000 and/or a custodial sentence.
