The problem is the moment you are born in Temasak you are a
product of the Ruler, With no human rights.
Lets say you decide to go to amsterdam and smoke up at the
coffeeshops Legally and then on your return, you find yourself
being asked by cnb officers to go for a piss test, and your urine
is posivite for cannabis, So what happens now? will you get
charged?
And what happens if say you are a drug addict who have decided
to go clean, and 2wks into your drug free life, you get rounded up
by the drug officers going around singapore looking for people who
looks like a drug addict and then make you go to the police station
to do a drug test.? so how now???
You dont need to have drugs on you!!! all you need is drugs in
your urine to make you go to jail.
so how to go to amsterdam like that?
Pay money and undergo a complete blood change.
Depends if you're scared of pain or scared of being
arrested.
It's your choice right? 
But if you're scared of both, then maybe you can go and kill
yourself.
Because I don't think those police in HELL will arrest you cos
good policemen goes to HEAVEN. Only those corrupted ones stays in
HELL and will smoke together with you.
