Several years ago I switched from Marlboro Reds to 'rolling' my own with a Micromatic machine due to the cost. I had withdrawals even while smoking the new ciggs and I believe it's because the pipe tobacco in RYO ciggs doesn't have all those chemicals and additives or the same amount of freebase nicotine.
I'm still hooked on the non freebased tobacco, but I believe the chemically doped stuff strengthens its addictive potential.
The nic in vapes still leaves me wanting a cigg. I have heard a theory that the combustion of tobacco produces additional chemical compounds and perhaps that's what I'm craving. Also, the whole tobacco alkaloids mentioned earlier seems very interesting.
But in short, to me it seems that premium ciggs are not exactly the same as natural tobacco and that's not exactly the same as what we vape. And in that decreasing order of addictiveness. I have never craved vaping.
Very interesting thought brad, i too believe something more is going on with cig consumption opposed to vape consumption
