Aside from saying you saw it on Nightline, can you show us the evidence that it is physically addicitive? Changes in the brain are not evidence of it, and nor is your experience with addicts (psychological addiction is obviously possible, perhaps even fairly common to those with addictive personalities). I'm sorry, but the fact that I've been able to smoke 1-2 times a day for months and then quit for several weeks/months directly following that seems to contradict your claim.
