Ofcourse it is. Conditional response.
Test increases Dopamine.
When u start think about your "fix", your brain releases Serotonin.
Same happens to those of you....eh..us, that has done recs. ie while cutting the lines or rolling the joint. (emphasis on HAS.....and regret)
Same as before u have sex, or any other enjoyable activity.
Ofcourse u release Seratonin, and also Dopamine during sex, eating chocolate, riding a cool car, or any other pleasurable activity.
But according to the theory of "conditional response" (Pavlov´s dog), the release of "happy hormones" will actually take place BEFORE the event.
I had the same feeling pinning.
Enjoy!
