I'm moving to Singapore in the beginning of January and I just realised that some of the pink leafs on my bathing shorts are marijuana leafs (I think it's pretty subtle, but it's still there). I'm a bit worried as Singapore seems so anti-drugs and actively censor a lot of stuff. This combined with the employment pass saying "I shall not take part in any political or other activities during my stay in Singapore, which would make me an undesirable or prohibited immigrant under the Immigration Act.".
Is it allowed to wear this kind of clothes? Will people care? What if it was a t-shirt with a giant leaf with "legalise marijuana!" written all over it? I don't own one of those, but would like to get a feel for where the limits are.
This might be seem like a silly post, but I'm not used to censorship or the harsh laws and I have no idea what the culture is like over there which is why I'm asking. Better safe than sorry

I don't use drugs and have no intentions on starting now. I don't really care, but if someone asked I would say I'm pro legalisation of marijuana, but that's from a "not putting too many young people in prison" and "freeing up police resources for real crimes" than a "I'd like to smoke it"-point of view.
Thanks in advance and a happy new year!
