Tobacco absorbs and concentrates radioactive metals in soil and fertilizers. Cannabis does not do this. https://www.cdc.gov/radiation-health/data-research/facts-sta...

The tobacco industry was well-aware of the risk from radioactivity since the 1950s. https://www.uclahealth.org/news/release/big-tobacco-knew-rad...

Thanks for the information. I wasn't aware of this, and this definitely aligns with the findings in the article.

I'm going out on a limb here, but I'm fairly sure that when you put _smoke_ in your lungs, radioactivity is the least of your worries.

My understanding is that inhaling polonium is one of the main vectors of lung cancer in tobacco smokers. Smoke inhalation is bad, afaik it's the main way people die in structure fires, smoke has carbon monoxide and formaldehyde and all sorts of bad stuff, but tobacco is particularly deadly, and afaik polonium from the fertilizer is a big part of why that is.
