This is to me one of the most important paper of the decade in the addiction field. It kicks to the curb both the incentive sensitization theory and the aberrant-learning theory of addiction and is in accordance with the opponent process theory. Good thing our lab is focused on the last one.
A beautiful paper by a great scientist, Ingo Willuhn. A must read.
