Years ago there was a paper that discussed how radioactive particles in tobacco, inhaled during smoking, and lodged in the lungs is where cancers started. They suggested that potash, used as fertilizer, was the source of the radiation.
It disappeared.
But sometime later it was noted that by growing tobacco you could decontaminate irradiated soil because tobacco naturally absorbed it.
Back in engineering school (1980) an old guy getting his PhD was living in our Freshman dorm room for the year - great guy. Looking back now it seems really odd, but no - he wasn’t a pervert!
He smoked a pipe and he dumped it out into the toilet in front of us. When it hit the water all of the particles spread out like they were magnetic and repelling each other.
“Yeah - it appears that there is an electrostatic charge on the particles. I wonder if it is that energy that is zapping your body when you inhale it and that causes cancer? Anyway kids - don’t smoke!”
