Local laws and customs
A serious violation of local laws may lead to a jail or death sentence.
Penalties for possession, use and trafficking of illegal drugs can result in long jail sentences and heavy fines. This applies even to personal use of small amounts of marijuana. British nationals have been detained solely on the basis of drug tests.
Carry some form of identification at all times and make sure your next-of-kin details have been entered into the back of your passport.
Homosexual relationships are not illegal. Younger Koreans are more liberal and gay rights organisations are gaining support. The gay scene, although relatively small, is well established and growing in visibility.
