When I used to smoke dope- we called it 'getting F--ked Up' for a reason ;-)
Personally, I think it's "spin" to try and set up the surgeon question as the only basis by which the determination of "dangerous" is made. Denying the "mind altering" qualities of tobacco essential attempts to dismiss what are arguably the most dangerous aspects of it. I don't recommend either one, but trying to downplay one in order to demonize the other is simply pushing an agenda.
