Inhaling any smoke is not healthy for you at all. But people who use the argument that cannabis is just as harmful as cigarettes, don't usually consider that people don't smoke cannabis like they do the mass quantities of cigarettes.

But that's how cigarette companies make their money. On the other hand, you don't usually see people chain smoking joints.
