To extend on what apoptosis said above, the physical part of substance addiction (the body readjusting to being without an internalized substance) is often acute, but is also very short-lived. The long term recovery of a substance abuse addict and a (for example) gambling addict are extremely similar. If you take an MRI of a heroine addict's brain and a gambling addict's brain three weeks after their last "fix" the neurological phenomenon associated with cravings in both are virtually identical. Make no mistake, a gambling addict has a "body" craving just like the heroine addict. Both the drug and the activity cause release of neurotransmitters that act on the emotional centers of the brain. It's the neurotransmitters that people become primarily addicted to, the activity/substance is just a means to an end.Col_Pladoh said:IMO that can be summed up as physical addiction is both a body and mind craving that id not satisfied has adverse physical effects on the addict. A mental addiction is simply the demand fulfillment of a desire, likely indicating a lack of will power and/or extreme egocentrism, the failure to satisfy that desire affecting the mind of the addict, and that possibly causing further adverse physical effects.
