Interesting. I totally agree. I started dating a wildly psychotic man while smlking cigarettes a lot, come to think of it. I think I had a case of influenctial psychotic syndrome- where one starts taking on the reaits of the psychotic person the more alone time they have with them isolated from most social interaction. Of course, there was also heavy drinking and cocaine involved as well. I've abstained from all of this for several years now but recently got into e--cigs.
Though I would certainly believe that all the additives and chemicals in a regular/normal cigarette could very well have the potential to influence one's perspective on reality to some degree, and of course if a person is presdisposed to addiction as a way tot slef medicate their underlying mental illness, then yes, you could blame the cigarette, but then you would'nt really know if a certain person was predisposed to such influence until they took up smoking (Which I highly do NOT recommend).
Now, if you're just puffing an e-cig, that's pure tobacco, no filter, no lighter needed because you're not actually smoking but breathing in tobacco flavored air (in a way, that's the gist of it) . All that stuff they put in normal cigarettes truly are deadly. The few times I smoke weed (the first time in a while the other day) and I couldn't help but notice that the 'smoke' was the same as that of the e -cig (electric cigarette).
So not only do cigarettes smokers damage their lungs, they also ingest poisonous chemicals like those found in rat poison and fertilizer.
