There's actually no issue with chewing gum anywhere in Singapore.

It's just that their sale is forbidden. If you have a pack you chew from your travel to Malaysia nothing will happen to you -- but you better not stick it in any public property or throw it down when you're down...

Downvotes, really? As this is misleading or offensive or something? I've lived in Singapore for 3 years on and off, perhaps those downvoting know better?

Check here for information too, if you don't believe me:
