I smoke myself but drink only very small amounts and it is very rare that I drink at all. But I smoke like a chain. It is unhealthy and maybe I will switch to a electric cigarette. Does anyone know if electric cigarettes are really better for your health? They are rather new and probably not truly tested yet.
There's actually quite a lot of research already done, and more coming. The trick - as with so many things - is to research the research, and make sure the conclusions are valid, and not being spun for an agenda.
I will say that, generally speaking, just about anything's going to be an improvement over sucking tobacco smoke into your lungs.
Also, there are a lot of different things that come under the heading of "e-cigarette". What, exactly, were you looking into?
