For all practical purposes, yes. Smoke is smoke, and none of it is good. Cigars and pipes are not as bad because you don't inhale, but still not the ideal. Inhaling any kind of smoke into the lungs is not a good thing.
Yup, this seems to be the medical concensus. You could smoke dried broccoli and still have about 95% of the risks of smoking cigarettes.
That said, tobacco companies are not lying, those additive free cigs ARE safer, it's just that they're only like 1% safer, so they're misleading customers into thinking the health benefits are much greater than they really are.
Other alternatives, such as snus are proven to be 98% safer than cigarettes, and, while there is no solid evidence yet, I suspect that e-cigs would come close to that figure too.
One thing to consider: In the poorest regions of the world, people with no access to electricity or gas use wood/dried dung to cook their meals, heat their water and, to an extent, their huts. This created indoor smoke, which in turn is thought to be amongst the chief reasons for these people's low life expectancy.
Bottom line : smoke is bad for you, avoid it if you can.
Edit: That said, don't obsess about it either. sitting at a campfire won't kill you, nor will second-hand smoke.
