http://news.independent.co.uk/world/science_technology/story.jsp?story=534938Morphine acts on a part of the brain known as the opioid system, which is linked to pain, pleasure and addictive behaviors.
The emotional bond between a child and its mother may be linked to the pleasure pathway in the brain stimulated by addictive drugs.
Young mice lacking a working opiate system in their brain took little or no interest in their mother's absence compared to ordinary mice who cry out endlessly when she is taken away.
Previous animal research had implicated the opioid system in the forming of lasting attachments but exactly how it did this was unclear.

So the attachment that infants feel towards a mother is created from opiates released in the brain? Maybe you can blame bad parenting for your drug addiction.
