Lighting shit on fire produces carcinogenic material.

That's about all the science on MJ smoke (vs vapor etc) that I really need to know.

Heat is well known to cause cancer, including in the form of hot beverages; but the contents of smoke aside from CO2 and H2O depends entirely on the source of combustion.

I'd not heard this about heat. It doesn't seem like an entirely straightforward link to me - aren't saunas supposed to fight cancer?

Since cancer is caused by certain mutations and heat can induce mutation, ingesting hot things can be mutagenic and thus carcinogenic.[0]

Saunas at the right temp for the right time can induce the expression of protective heat shock protiens.[1]
