These things are illegal in multiple countries. In the US they are under high scrutiny and will likely soon be illegal. The FDA has found that they contain carcinogens. According to Wikipedia, "The term carcinogen refers to any substance, radionuclide or radiation that is an agent directly involved in the promotion of cancer or in the increase of its propagation." The manufacturers lie about what's actually in the product. There were some that claimed to be nicotine free, yet upon testing, they actually did contain nicotine. I don't trust this crap, it actually looks to me like it's worse than a normal cigarette, if for no other reason than people seem to think it's not.
You might want to look at nicotine research. Did you know it's toxic? It's a lot more dangerous than you seem to think.
I highly advocate quitting smoking, whether they be real or fake cigarettes.
That said, I think I'll step out for a smoke. I smoke real Marlboros, not the wannabe fake crap.
