Another lie Jane.  I have provided you with the info on this.
You have nothing credible to the contrary.  The only thing
bad about cannabis to the lungs is the leaf-burning by
products if a person smokes it -- and this is pretty much the
same whether it is the leaf from a tree or wood smoke.  There
is no lung harm from vaporizing the medicinal contents of marijuana
(by heating it to a temperature lower than burning), or cooking it
and eating it in food.
