The first swimmer from Singapore to win an Olympic gold medal, Joseph Schooling, has been barred from swimming competitions after confessing to using marijuana abroad.
“I demonstrated bad judgment and I am sorry,” he said.
The 27-year-old became a local sporting hero when he won the country’s first Olympic gold at the 2016 Rio Games.
But the scandal has now divided opinion in a country known for its strict drug laws.
Many expressed sympathy for the national swimmer, noting that his father had died last November and he was facing immense pressure as an athlete.
“Every young person makes mistakes,” one person commented in an article about the case. Another wrote: “This is a nothingburger. Many have tried it overseas.”
“It is totally unacceptable as a top sportsman who is supposed to be a national role model,” a Facebook commenter said.
Singapore regulates the consumption of controlled drugs – such as cannabis – not only within the country but outside of it as well. Citizens or permanent residents who fail urine tests for illegal drugs on entering the country face up to 10 years in prison and a S$20,000 ($14,300; £12,300) fine.
It also has a mandatory death penalty for drug trafficking, which has become increasingly controversial as more young Singaporeans begin to speak up against capital punishment.
In a statement, Mr Schooling apologized that his actions caused hurt to his family and young fans who looked up to him.
“I gave in to a moment of weakness after going through a very tough period of my life,” he said.
“There is no excuse, and I will take the warning given to me seriously and reflect on my mistakes,” she said in a statement.
Singapore’s Ministry of Defence said on Tuesday that Mr Schooling passed the urine drug tests, but the 27-year-old confessed that he consumed cannabis while he was on a break from his military service to train and participate in the Southeast Asian Games in Hanoi, Vietnam in May.
Given the “abuse of disruption privileges”, Mr Schooling will no longer be able to take leave or disrupt his military service to train or compete, the ministry said.
He will also be put on a supervised urine test regime for six months and could be sentenced to up to nine months of detention in military detention barracks if he tests positive.
All male Singaporean citizens and permanent residents have to serve about two years of full-time military service, usually starting when they are 18 unless they are exempted.
