A powerful anti-smoking ad from Thailand where children with cigarettes in their hands ask smokers for a light and the smokers chide them on the harmful effects of puffing tobacco has gone viral.

The video, which can be seen below, was created by Ogilvy Thailand for the Thai Health Promotion. It shows smokers puffing and then hypocritically telling the kids, who approach them with cigarettes in their hands, not to smoke.

Titled Smoking Kid, the 1-minute, 37-second video has nearly 800,000 views on YouTube.

The video starts off with smokers puffing away, followed by a black screen with the phrase, How would they feel when a child smokes? in white letters.

Children are then shows asking smokers for a light.

Really? one smoker asks. Smoking is bad, you have to stop, she tells a girl approaching her.

If you smoke, you die faster. Don't you want to live and play? another smoker says.

A third tobacco addict warns a young child about the harmful effects of smoking.

Cigarettes contain insecticide. You look old when you smoke, she says.

A 20-something smoker tells a child asking for a light, when you smoke, you suffer from lung cancer, emphysema and strokes.

Every adult filmed reminded the children that smoking is bad, the ad goes on to say. But did they forget something themselves?

The children then ask, so why are you smoking?, and hand the smokers slips of paper that say in Thai, You worry about me. But why not about yourself? Reminding yourself is the most effective warning to help you quit. Call 1600 hotline to quit smoking.

The smokers are then seen folding up the paper and putting it in their pockets.

Almost every adult who received a brochure stopped to think and threw aware their cigarette, the ad says. No adult, however, threw away the brochure.

The ad then ends with a young boy and girl with stoic expressions on their faces.

Smoking Kid was lauded by YouTube users who say the ad was highly effective.

 This is the best DO NOT SMOKE ad that I have ever seen, said user Erick Tollen. I commend [sic] the person or person;s [sic] that came up with? it. THE BEST.

YouTube user KatHalfaker23 said the ad brought tears to my eyes.

I've never smoked a cigarette or had a drink. I want to keep that going. Lead by example, the user said.

DarkAdonis255 was equally wowed by Smoking Kid.

Whoever thought this up deserves a prize of some sort, they said. I could see similar campaigns changing lives around the world.
