JACKIE Chan supports the use of the death penalty for some drug offenders.

The 61-year-old movie star - whose son Jaycee Chan spent six months in prison in China after police uncovered marijuana in his home - has voiced his support for the death penalty in some cases, saying with drugs "you're hurting thousands of young children".

The actor, who is Singapore's first celebrity anti-drug ambassador, said: "On some issues, I do support the death penalty.

"When you're hurting thousands and thousands of young children, I think these kind of people are useless.

"You should get the right punishment."

Jackie - whose 32-year-old son was imprisoned for providing a shelter for others to abuse drugs - has insisted the use of drugs is not acceptable in his family.

He explained: "[Young people say] 'it's okay, it's just like a cigarette'. I say 'it's not okay, not in my family'."

The 'Rush' Hour' star also confessed to feeling "ashamed" and "shocked" by his son's imprisonment.

He said: "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."
