​One could speculate that the people who get addicted are either low in
endorphins as a result of their usual lifestyle (or perhaps even
genetically low), or are high in them and the drug or whatever is just a
fantastic, incredible high unattainable any other way.​

​  I was instantly addicted to morphine at age 9 after ear surgery.  Have
not felt that good since.  No pain was the very least of it.  Perhaps would
have been satisfied to stay that way.
