You don't necessarily need to be a drug addict to enjoy edibles or a joint every now and again. It's a really fucking nice way to unwind once in a while. That said some bits of SG life seem good, I only visited briefly but the food and the public transport was pretty good. If you don't ruffle any feathers and you have a well-paid job your life in Singapore would probably be pretty fine. However 30C year round might be a little bit repetitive.
