But now, Jackie Chan has revealed that he supports the death penalty for some drug offenders.

Speaking at an anti-drug press conference in Singapore, the Hong Kong film star, 61, known for his roles in Rush Hour and Shanghai Knights, said: 'On some issues, I do support the death penalty.'

In apparent reference to drug traffickers, he continued: 'When you're hurting thousands and thousands of young children, I think these kind of people are useless. You should get the right punishment. '

Chan's son, Jaycee, 32, was released from a Chinese jail in February following a six-month prison term for 'sheltering others to take drugs' after police found 100g of marijuana at his Beijing home.

But on Thursday, his famous father condemned the use of illegal substances, telling reporters: '[Young people say marijuana] 'it's okay, it's just like a cigarette.' I say, 'It's not okay, not in my family.'"

Chan - who was named Singapore's first celebrity anti-drug ambassador during his appearance - also admitted that he was 'shocked' and 'ashamed' when he found out about his son's drug crimes.

'I would never think it would happen to my family. The day I found out, I am so ashamed, I am so angry. How (did) that happen? ' said Chan, also a martial artist and a film director and producer.

'I was very angry but it made me more determined to be against drugs.'

He said he was now more focused on his son, telling reporters: 'I'm more concentrating on him now, used to be just, "you are a grown man". But now I find out, he's still a boy,' according to the BBC.

Chan - who was named official Narcotics Control Ambassador in Beijing six years ago - sought to deter the Nanyang Polytechnic students at Thursday's event from getting involved with drugs.

'Don't ever think you won't get addicted, because not only are you hurting yourself ... your one drug addiction will hurt your family,' the actor told the gathered students, who were excited to see him.

'In order to earn money, you'll steal, you'll rob. In the end, you're hurting your country, you're hurting your family, you're hurting your son.' Chan referred to the escalation as 'a domino effect'.

Jaycee Chan, an actor and singer, was imprisoned for using marijuana and for 'providing a shelter for others to abuse drugs', Beijing police said. He tested positive for marijuana at the time.

Although Chan could have been sentenced to up to three years by the judge, he was reportedly shown leniency for having come clean with his law breaking , which took place at his apartment.

Upon his release in February, he apologized and begged the public for a second chance, telling reporters in Beijing that he was rededicating himself to his family and an entertainment career.

He said he had 'no reason, no excuse' for the behavior that led to his arrest last August - alongside Taiwanese actor Ko Kai and others - in an interview that was broadcast live on Chinese television.

'I made mistakes, I will remember this lesson, I won't commit mistakes again in the future,' Chan told reporters and the public. 'I want to apologize to everyone for my mistakes. I'm genuinely sorry.'

His father has pledged to work with him on his recovery.
