my understanding is that nicotine causes the adrenals to release adrenalin, and that the 'rush' 'of relief from need) is caused by the adrenalin.....meaning that the true addiction is the adrenalin
You could be right. I smoked for about 13 years, and then quit in 5 days, that was over 4 years ago. I tried one of my mum's last week and nearly vomited though, lol.
