Smokers, please do not use public transportation

I believe that not only secondhand smoke, but also the lingering smell on smokers themselves
can sufficiently promote cancer cells in my body.
Even without research results,
my body knows this instinctively.
I view them as nothing more than potential clusters of germs.
To protect the health of non-smokers, smokers should be barred from using public transportation altogether.
I believe this is a natural right of non-smokers.
Otherwise, a sterilization system for smokers should be created before they board, so they can wash up and eliminate the germs on their bodies.
Now that I am 1 year and 4 months into quitting smoking, I think I finally understand the mindset of a non-smoker.
