Please provide proof that nicotene CAUSES lung cancer. Not epidimiology, which merely shows correlation. But proof that nicotene CAUSES lung cancer.

Po-210 is relatively long-lived fallout from the decay of radon in the atmosphere close to tobacco plants. This in turn comes from the decay of uranium-contaminated calcium phosphate fertilizer used on tobacco fields. Sub-microscopic particles of Po-210 in the air are trapped on sticky hairs on the leaves of tobacco plants. These hairs are very hydrophobic, and once trapped the radioactivity does not wash off in the rain. Other crops are not affected.

The Polonium in tobacco is provided by phosphate rich fertilizers. the same fertilizers that are used to grow food. This fertilizer is in the soil and in all the food we eat. Further, it is in the dust that we breathe
Polonium 210 in tobacco has been thoughly investigated. It is in background level too small to cause lung cancer.
Half-life means you have half the amount after 138 days not that it has disappeared. You'd still have 12.5% of the original amount after 414 days.
Further, the half-life of Polonium 210 is only 138 days. Think of how long tobacco is cured (usually a year)
Lung specimens from 25 current cigarette smokers, 2 current pipe smokers, 1 former cigarette smoker, and 8 nonsmokers ere analyzed. The average concentration of polonium in the peripheral parenchyma of current smokers was .0074 picocurie/gm and in nonsmokers was .0016.

And again - neither amount is sufficient to cause you harm. If it was polonium causing the lung cancer, then every smoker would get it. Remember that this does not happen.
Statements that "4 times the amount" sound scary but parts per quadrillion are equal to 1 second in 35,000 years.
Critical support for this thesis is based upon experimental animal studies in which lung cancers that resemble adenocarcinomas are induced with as little as 15 rads of radioactive polonium, equal to one fifth the dosage inhaled by cigarette smokers who average two packs a day during a 25-year period.
