Well done, you can observe. It's straight forward propaganda.. with empirical evidence that you can try yourself.. so if you can't take hints from the video and shout 'propaganda' at everything then have fun with your black lungs (that is.. if you smoke).
So do you north americans get lectured often on the dangers of cigerattes? Just wondering cuz any anti compaigns here are non existant.
Yeah, Yeah, Yeah... we all know. It's not like ALL the tar you've inhaled since day-one of smoking is still in your lungs. Your body is constantly removing it (and burns calories in the process). But no one can argue that eventually after years of smoking your body cant keep up.. and then it starts to build. Educate yourselves.
Apparently it depletes really really slowly though.. like if you smoke casually for 6 months it would take 3-4 years to completely dissapear.
Yesterday when I was high I decided I would quit smoking forever, because I was inhaling and when I laughed it came up weirdly so I didn't inhale all the way and i was convinced that I felt the tar in my mouth. Anyway, it lasted about one hour. The video is gross, but I highly doubt any smokers are going to quit just from seeing that...people who smoke usually know the risks, and that it can cause lung cancer. Repeating it over and over isn't going to change anything.
I hate smoking cigarettes, and wish I never had started... waste of money, waste of time, and damaging to my body. I was always one of those people who thought they could quit smokin them no problem.. but the longest I ever toughed it out for was a couple weeks. It just becomes part of your routine..
Try some test on your own with a cigarette, something to hold it with, a vacuum, and some good filter. Maybe use some activated carbon and measure the mass gain before and after.
