Chewing gum
Prohibited in: Singapore
Reason: Cleanliness
Many people use chewing gum to prepare for an important meeting or date to improve the smell of their breath. There are certain places in the world, one in particular, where anyone who wants to get rid of bad breath quickly would be better off choosing a mouthwash or a breath mint. In Singapore, gum chewing was banned in 1992 to clean up the streets. Although chewing is allowed in public, a doctor’s prescription is required. You could face a fine of up to €85,000 or a jail term of up to two years if you do not provide the appropriate documentation.
