From your own quote, I emphasise: > (1) Any person who is proved to have had in his or her possession or custody or under his or her control So no, as much as you want to think of Hollywood-esque scenarios where a friend or some random plants a drug on you, which gets you the death penalty for being completely innocent, you actually get a lawyer and a trial in court where you can prove your innocence. Singapore does not do kangaroo courts. The prosecution needs to prove beyond all reasonable doubt that you conspired with said friend to hide the key in your locker. And needless to say they also have to prove you had the knowledge that said key controlled access to narcotics. And chances are, this has never happened in reality because drug traffickers into South-East Asia are an extremely close-knit group who in general don't go around handing 'drug locker keys' to their friends and random people on the street. The law exists to prosecute conspirators, not randoms.
