I think there are two sides to addiction; the psychological and the physical. The simple 'hand to mouth' action and 'seeing' the smoke/vapour might be considered the psychological. The physical is the effect nicotine has on our bodies. Nicotine changes the brain's make-up and, as I have previously mentioned, is a very mild anti-depressant in that it stimulates the brain to release dopamine.
Again though, we are all individuals with our own brain make-up and our own psychologies. There are some amazing people out there who can give up the cigs cold turkey and after a couple of days be OK about it, as my grandmother and exboyfriend did (needless the say, the exboyfriend couldn't understand why it was so difficult for me to quit, he behaved like a jerk and had to go!). From my own experience, though, I had to know myself in order to get off the stinkies. I knew that the control element of my brain, the stubborn, challenging part, would like to have a go and so I would challenge myself to only have 10 cigs a day (very early on!), then 5...suddenly it was 2, then 1. That final one, first thing on a morning, was very much about the quick fix.
When friends have asked about my success this time, I tell them that I 'believe in the magic'. It's a strange thing to say, perhaps, but this time I KNOW it will work.
But then there is the physical side. I had to up my nicotine to 24mg when I first came onto e-cigs full-time to get me over that first few hours. Physically, 11mg hadn't cut it when I first started out last year (and failed!). 24mg, dropping to 18mg did cut the mustard this time. Again, physically I realised that 18mg was keeping me up all night and dropping to 11mg wouldn't be a bad idea. To keep me at it, though, psychologically I was remembering that it was my choice to do this.
This is where we reach the 11mg/8mg conundrum. Half of you seem to go with the physical, while the other half are psychological. Either way, it doesn't matter because whether it is a physical or a psychological thing, I wasn't ready- and after only 7 weeks on the e-cig, I don't think that's too much of a bad thing! I wonder if we actually thought about our own psychologies (I'm no psychologist but I like to think I know myself pretty well), if this might partially explain why some people seem to manage it easier? Perhaps that dopamine rush is more important for some than others, perhaps for genuine health reasons?
As for the is nicotine as addictive as caffeine or ......, I've never tried ...... so I wouldn't like to comment on that side too much although I would point you to this article;
Is Nicotine Addictive? It Depends on Whose Criteria You Use - New York Times. However, if I don't have my caffeine, I am ratty, irritable, bad tempered and exhausted...not to mention the headaches (oh those cruel, cruel headaches!)! If I went cold turkey from nicotine, I think I'd have to be locked up in a padded cell!
Finally, what exactly do they add to nicotine to make it more addictive and does it become an entirely new compound?x
