Got lungs? Maybe avoid inhaling chemicals that might harm them

I'm curious how you reconcile your decision to smoke tobacco while also thinking people are responsible for all their decisions. Do you accept that you're making a terrible decision? And if so what kind of person does that make you?

fact: cars kill people indirectly via fumes.

so i'd rephrase your idea:

"Got lungs? Maybe avoid <living on planet earth>"

Yes, but you can't really control whether or not you're exposed to car fumes. Some toxicity is very hard to avoid

The toxicity from smoking is entirely avoidable by not engaging in it
