"Along with me, youngsters of the country and sportspersons of the country are disappointed," Singh told media.
"Now the bigger picture is how do we prevent this from happening in future? What are the steps the government needs to take?" he said.
"We are thinking on it. We will bring out a protocol soon," Singh said.
The National Anti-Doping Agency (NADA) on Wednesday took blood and urine samples from boxer Vijender Singh, accused of buying and consuming heroin.
The tests, meant to test him for athletic performance drugs and not for heroin, came on a day when his close friend and sparring partner Ram Singh was arrested by the Punjab Police.
The Punjab Police on Sunday alleged that Vijender Singh had taken heroin 12 times from an Non-Resident Indian (NRI) drug dealer who was earlier arrested.
The police said Vijender Singh bought drug along with his friend and fellow boxer Ram Singh from the dealer. They had purchased drugs from December to February this year, police said.
