I think you are talking about the IQOS. There are several threads on this forum about it, you could do a site search and read up about it. I don't think the IQOS is a terrible thing to add to the harm reduction market, but from what I've read I have no interest in trying it, mainly because I'm happy where I'm at, it sounds like it has several serious design flaws, and it's not versatile like a vape. I'd be shocked to find out if it was AS SAFE as e-cigs, but it's probably safer than cigarettes. I think there will be a market for it for some smokers who may have failed at vaping (most likely cigalike products) and I am quite sure it will be marketed heavily, so it may help some smokers transition, even eventually to vaping. Whether they do or not, I'm not opposed to another harm reduction product on the market, even if I consider it unsuited to my needs, because I could see some smokers trying it and being successful (but most likely, poor, or at least, paying the same as smoking).
I guess we'll see how it pans out when it gets here.
I have never tried to vaporize tobacco and I tried a hookah once. Once, because it was the foulest thing ever, though I think? it may be less harmful than smoking, but Idk for sure....
