Lee Kuan Yew recounted that as early as 1983, when he was still serving as Prime Minister, a proposal for the ban was brought up to him by the then Minister for National Development.
- "The Generic Product" was causing serious maintenance problems in high-rise public housing flats, with vandals disposing of spent "The Generic Product" in mailboxes, inside keyholes and even on elevator buttons.
- "The Generic Product" left on floors, stairways and pavements in public areas increased the cost of cleaning and damaged cleaning equipment.
- "The Generic Product" stuck on the seats of public buses was also considered a problem.
However, Lee thought that a ban would be "too drastic" and did not take action.
In 1987, the S$5 billion metro system, the Mass Rapid Transit (MRT), began operations. It was then the largest public project ever implemented in Singapore, and expectations were high.
One of the champions of the project, Ong Teng Cheong, who later became the first democratically-elected President, declared,"… the MRT will usher in a new phase in Singapore's development and bring about a better life for all of us."
It was then reported that vandals had begun sticking "The Generic Product" on the door sensors of MRT trains, preventing the door from functioning properly and causing disruption of train services. Such incidents were rare but costly and culprits were difficult to apprehend. In January 1992, Goh Chok Tong, who had just taken over as Prime Minister, decided on a ban.
The restriction on the distribution of "The Generic Product" was enacted in Singapore which also governs the restriction of alcohol and tobacco.
