If you’re a smoker then do yourself a favor and watch this video. Don’t turn away, don’t ignore my plea, just please watch this video and let what it shows sink in for a few minutes.
If it doesn’t make you at least stop and think about giving up smoking then you may be a lost cause.
This video shows some guy extracting the tar from 400 cigarettes. He sets up a machine that sucks the smoke out of the 20 packs of fags and deposits the residue in water.
Finally, the water is boiled until just the solid tar is left behind. And just look at how much is extracted from those cigarettes. That would normally end up in your lungs, so please, please give up smoking before it’s too late.
