That study is a load of shit! I was a cig/nic smoker for 10+ years and still I want them so badly, mind you I haven't had the cig/nic for 2 years now. I stoped smokin buds for 6 days last month cause I had to leave home, none of the withdraw above mentioned occured, sure it would have been nice to burn one but really I never craved it physically the way I needed the cigs/nic. They were probally rollin "spliffs" for the people in the study and so they were really having tobacco withdraw unknowingly.
