Inhaling the smoke of burning tobacco leaves can cause cancer. I am fairly certain nobody has as strong of an incentive to create cancer-free tobacco as tobacco companies do. That does not mean it is possible, right?
"Some products are inherently unsafe, and that is precisely what the costumers want."
Radioactive material in tobacco might be mutually exclusive from nicotine and MAOI content. My layperson guess is getting rid of the radioactivity would require prohibitively expensive hydroponic growing. It's the drug part that consumers want, and I'm pretty sure if given the knowledge and option they'd go for non-radioactive cigarettes.Swedish snus is made to minimize tobacco-specific nitrosamines (TSNAs), but seems to not address Polonium-210 on account of the radioactive stuff being "comparable to that from the natural background radiation sources or dental x-rays": https://harmreductionjournal.biomedcentral.com/articles/10.1...
That excuse doesn't seem to hold up to scrutiny. Who really wants to have 10-20 chest x-rays done per day? Are "dental" x-rays really as weak as "background" radiation?
Alcohol seems to be in a similar position - see the popularity of nice wine and beer over e.g. guzzling cheap spirits.
I think people want health AND pleasure, and are willing to do their own hedonic calculus.
What's the safe, reasonable, recommended smoking amount?
My point is that reality limits how much safer you could make a product. Would it be nice for cigarette or alcoholic beverages to be safer? Yes. Is it possible? Apparently not.
Either tobacco becomes a controlled substance (I am deeply opposed to this given the catastrophic social consequences of prohibition in general), or adults behave like adults, understand the risks, decide for themselves and accept the consequences. Maybe it's because I'm European, but anything else sounds like insanity to me.
By the way, I am not being judgemental in any way. I am an ex-smoker and I drink socially. If people want to smoke (without polluting the environment of others who don't) it's their right, and I completely understand. I used to love it too.
Possible to improve? Yes, perhaps significantly. Economically and politically feasible? Maybe not so much.
