As I have been saying for quite some time only about 20% of the population is susceptible to "addiction". And the idea of addiction itself is cargo cult science.
People in chronic pain chronically take pain relievers.

And what can be done for the victims of child abuse? Those will not be brought in right after the traumatic event. Well there is marijuana. Two more states will be voting on med pot this fall. Massachusetts and Arkansas.The results, the researchers said, supported their hypothesis that the NMDA-mediated nitrous oxide production is important in successful formation of fear memories, and disrupting that interaction could potentially offer a means of preventing long-term post-traumatic stress disorder symptoms
Repeated intense activation of the brain network for fear makes it vulnerable to developing hypersensitivity, said Shekhar, Raymond E. Houk Professor of Psychiatry and director of the Indiana Clinical and Translational Sciences Institute.
"The majority of people who have a traumatic event, perhaps about 80 percent, will have some post-traumatic stress disorder symptoms for a few days. Only about 20 percent will have long-term problems, but currently there is no way to predict who those people will be," Shekhar said.
With that uncertainty, it would be appropriate to administer the treatment to all traumatized patients within a few hours of the incident, such as when a person arrives at an emergency room after an accident or a field hospital after a military incident, he said.
The next steps would be to optimize compounds and begin drug development efforts, Shekhar said.
Shekhar will discuss "Post-trauma disruption of nNOS-PSD95 protein-protein interaction is an effective means to ameliorate conditioned fear," 3 to 4 p.m. Monday, in Hall F-J. Other Indiana University researchers involved in the work were Stephanie D. Fitz, Department of Psychology; Philip L. Johnson, assistant professor of anatomy and cell biology; Andrea G. Hohmann, Linda and Jack Gill Chair of Neuroscience and professor of psychological and brain sciences; Ted Widlanski, professor of chemistry; and Yvonne Y. Lai, Department of Psychological and Brain Sciences.
