We all know smoking damages our health, but one YouTube user has created a video that really hits the message home.
With a DIY science experiment, vlogger CrazyRussianHacker demonstrates how many chemicals are left in the body after smoking just one cigarette.
He places a white coffee filter at one end of a vacuum cleaner and a cigarette at the other, using cardboard to stabilise his apparatus.
He then turns on the machine to mimic the process of smoking.
The cigarette quickly burns down, and the vblogger holds the yellow-stained coffee filter to the camera.
"Look at the dirt inside of it, just from one cigarette," he says.
It's enough to put even the most die-hard smoker off cigarettes.
