Welcome to my fun little science experiment. I’m attempting to make my cigarette filter as black and dirty as possible. Hard smoking one cig can make the filter brown, but it has limitations. That’s just not good enough for me. I want to see how dirty the filter can get. The solution I came up with is using the same filter for smoking three cigs, by removing it from the first one and then replacing the fresh filter from next two chain smoked Marlboro Reds with it. I’m showing you the progression of the brown tar and nicotine drenched filter as I smoke. Heavy fast smoking and hard inhales. I must say the taste from that filthy cork filter towards the end was delicious. Have you ever seen a n”juicier filter? I call this a success!
