Nicotine has been demonized because of association with its extremely dirty delivery device....and unfortunately, unless there's a radical shift in public perception (riiiiight) always will be. Those radical shifts might be accomplished with the new head of the FDA, who does understand harm reduction, but still....its going to be a long, uphill battle.
I agree, nicotine SHOULD be in the same class as caffeine, but I'm just one small penny in the national vault
