Opium is actually illegal in Singapore. As to what would happen, if we look at Singapore today, there is not much impact actually. Lives still carry on as normal.
Great Britain would not stop its merchants from selling opium in China.
Of course not. You cannot work in Singapore with a visitor's visa. This would be illegal. You have to apply for a Singapore work visa.
The same as would happen in any other country: you could not use any electricity!
Singapore would get flooded utterly and nearly the entire island would be submerged underwater, along with large loss of life.
About half the population will die.
nothing
British merchants carrying no opium would buy tea in Canton on credit, and would balance their debts by selling opium at auction.
go to jail if caught
You would get into trouble. No school principal would allow you to get that close. It is illegal.
The clear answer is no. And if that would have been the case then opium would not have been haraam/makrooh in islam.
Well , the lifestyle of people would be affected .Outdoor activities would be cancelled too :(
First the airport. Get a plane ticket to America. Find a Petco or PetSmart. Buy the fish. Since it would be illegal to bring them back to Singapore, buy a home in America and get a job there.
