Tobacco causes cancer through Tobacco-specific nitrosamines generated during curing and burning. It’s not simply a matter of burning leaves.

That is debatable; burning leaves or burning anything can mess you up with extended amounts of exposure.

Firefighters have above-average rates of cancer, including lung cancer. This suggests that inhaling lots of smoke from ANYTHING on the regular isn't good for you. Example: https://www.nbcnews.com/health/cancer/cancer-biggest-killer-...

It’s worth discussing the risks from inhaling smoke, and thank you for the reference!

However, it is not debatable that they are the primary causative agents in tobacco-derived cancers. [0]

Burning leaves is no more harmful than deodorants.

Burning known and non debatable evidence of toxic chemicals in tobacco leaves harvest curing.

Marijuana comes out ahead.

So much misinformation about drugs. Heroin is safer than alcohol if moderately consumed. Addiction wise, not so great. but Tobacco is said to be harder to quit than heroin.

I can attest to that.

you get tar but when you light up a tobacco it has all sorts of chemicals. you are not just burning tobacco leaf, you are burning dozens of chemicals they add to it.

You can't even get high from second hand marijuana smoke outside.

Hotboxing your car however, will get you high. Certainly better than being in a car with a tobacco enthusiast.
