Quote from trendlover:
Rearden, I think of addict as someone who produces less of a dopamine, endorphins.....and other (chemicals?) then most people. So when they do try a drug for the first time, the feeling is so good for them, they crave it more then someone who trys a drug but has natural good supply of chemicals in their body. One just experiments, one becomes addict.
That's exactly what I've been saying for years (here, and on my website).
