About how much tar builds up in human lungs after 1 year of smoking?

Question

I'm doing a presentation on smoking and I'm gonna put molasses in a jar to represent tar from human lungs after smoking. Please provide sources if possible.

Answer 1

1 year's worth of tar in the lungs
Here's the amount of tar a pack-a-day smoker consumes every year. Some tar gets exhaled (one reason for bad breath).Some gets coughed up (gross). The rest stays in your lungs (oh-oh).

If this is how much a pack-a-day smoker takes in each year, imagine how much tar you would take into your body if you smoked until you were 30 years old...multiple what you see in the picture by say, 15, for 15 years. That means 15 beakers full of tar!

Tar can: Rot your lungs.
Kill your cells.
Cause cancerous tumours.

Imagine pouring hot tar used to repair roads on your hand and leaving it there. What do you think would happen to your skin?

....good luck.

Answer 2

Yes - you will have tar in your lungs if you smoke one or two or 50 years.
