Sorry in advance for giving rather long answers to questions on this friend's post. But I wouldn't recommend you try it out of mere curiosity.

Tobacco often has addictive effects, and industrial cigarettes have certain blends that can accentuate the addictive effects to a greater degree than their more traditional counterparts.

I won't say that traditional Habanos are harmless, just that they're less processed and have fewer ingredients in their blend.

In any case, I don't recommend them.
