Ghetto Science - Smoking

Most people haven't seen this, but I bet it would help more people understand why smoking isn't a good idea. Filmed in one take and completely produced in under an hour. If you think the results are fake, go ahead and try it yourself. And if you start smoking, you are an absolute idiot. For the record, I'm a smoker. I've quit, but that will never make me a non-smoker. Once you're addicted, you're a smoker for life. All I can do is try to always be a smoker who is not smoking today. The music in the background is Mozart's Requiem Lacrymosa. Anyone know why?
