That wording is exceptionally poor in my opinion. Just above, @blueprint, does a fabulous job of summarizing what I think is essentially the same idea (but with far better wording):

"..the problem is that for some people, addiction is connected with: * using an external means of dissociation * to obtain instant control over feelings * without relating to them on their own terms"

Someone who is without serious trauma won't likely have the same reaction/response to this level of dissociation.
