If you smoke ANYTHING then it cannot be good. Cannabis generally has to be smoked when mixed in with tobbaco unless its put in a bubble pipe aka morroco, tunisia etc.
If you introduce ANY toxins into your body then in the long term it has to be bad for your health.
Yes due to genetic history more people are prone to developing cancer than others. And sure cannabis isnt the only cause, neither are ciggarettes.
We walk doen the street - we breath in carbon monoxide. petrol fumes and the crap that comes out chimneys. Our bodies are riddled with toxins thanks to modern day life.
But anyone who belives that cannabis or fags do not do you any harm is clearing reading their evidence from books written in cloud cookoo land
