The key Australian Government site on the issue details an extensive analysis of studies on the topic.
It concludes:

Chronic heavy cannabis smoking probably causes chronic bronchitis, and impairs functioning of the large airways. Given the documented adverse effects of cigarette smoking,
it is likely that chronic cannabis use predisposes individuals to develop irreversible obstructive lung diseases. There is suggestive evidence that chronic cannabis smoking
produces histopathogical changes in lung tissues that are precursors of lung cancer. Case studies raise a strong suspicion that cannabis may cause
cancers of the aerodigestive tract. The conduct of case-control studies of these cancers is a high priority for research into the possible adverse health effects of chronic cannabis smoking.

But don't believe a word of it! If you want to know, look up the medical research directly, you can generally get a good gist despite the medical terminology, and the stats can be looked at properly - 90% of them are poorly done. My guidance is always the 1st surgeon general's report on smoking - they had to redefine the word "cause" in order to say that smoking causes lung cancer! As soon as governments get into science, it gets political, never trust them on issues that have a strong political side.

All the politics were in favor of pretending that smoking wasn't hazardous. Billion dollar industry >>>>>>>> well anything else as far as gov't is concerned.
As far as pot goes, yeah it's probably harmful, but most pot smokers smoke infrequently. Heavy pot smokers smoke, what?, a few times a day? Heavy tobacco smokers smoke almost constantly.
