Part of the scandal covered in The Insider is that tobacco companies deliberately added carcinogenic compounds to cigarettes in order to increase the impact of nicotine.
So sure, tobacco is still addictive, but as I said in my comment, my main issue is with the hacking/maximization of this by corporations. Especially when that hacking involves adding even more poisonous chemicals.
All forms of tobacco are inherently addictive due to the presence of naturally occurring nicotine, which is the main driver of addiction.
