I had always heard that part of the problem with tobacco smoke is that it's radioactive. Whereas marijuana smoke isn't. So it's still smoke but not nearly as carcinogenic?

You should not believe everything you read.

If tobbaco smoke was radioactive then the cigarettes would have been radioactive (you don't make a material radioactive just by setting it on fire) and would have caused a health hazard for stores employees.

This is well-established in peer reviewed research, it's not just something I read.
