     I've written 14 movies. My characters smoke in many of them, and they look cool and glamorous (有魅力

的) doing it.

     Smoking was an integral (必需的) part of many of my screenplays because I was a heavy smoker. It was

part of a bad-boy image I'd cultivated for a long time- smoking, drinking, partying, rock 'n' roll. Smoking, I

once believed, was every person's right. The second-hand smoke was non-existent problem invented by

professional do-gooders. I put all these views into my plays.

     Remembering all this, I find it hard to forgive myself. I have been an accomplice (帮凶) to the murders of

untold numbers of human beings. I am admitting this only because I have made a deal with God. Spare me, I

said, and I will try to stop others from committing the same crimes I did.

     Eighteen months ago I was diagnosed with throat cancer, the result of a lifetime of smoking. I am alive but

disabled. Much of my larynx (喉) is gone. I have some difficulty speaking; others have some difficulty

understanding me.

     I haven't smoked or drunk for 18 months now, though I still take it day by day and pray for help. I believe

in prayer and exercise. I have walked five miles a day for a year, without missing even one day. Quitting

smoking and drinking has taught me the hardest lesson I've ever learned about my own weakness; it has also

given me the greatest affection and empathy (同感) for those still addicted.

     I don't think smoking is every person's right anymore. I think smoking should be as illegal as heroin (海洛

因). I'm no longer such a bad boy. I go to church on Sunday. I'm desperate to see my four boys grow up. I

want to do everything I can to undo the damage I have done with my own big-screen words and images.

     Screen writers know, too, that some movie stars are more likely to play a part if they can smoke because

they are so addicted to smoking that they have difficulty stopping even during the shooting of a scene.

     My hands are bloody; so are Hollywood's. My cancer has caused me to attempt to cleanse (彻底清洁) me.

I don't wish my fate upon anyone in Hollywood, but I beg that Hollywood should stop putting it upon millions

of others.
