I think I follow your logic, but I think it has an ommission. Using your model, how do you explain the majority of people who use addictive things with no issue, they have reward pathways the same as the "addicts". Are there not other factors that make the difference between a user and an abuser of something? To use your example of mild boredom: boredom is felt by everyone yet most people choose healthy choices over addictive behaviour. Is there simply some luck in how we are exposed to an addictive experience or do some people seek addictive rewards to overcome some greater pain?
