Norepinephrine (NE) is the neurotransmitter often associated with the "fight or flight" response to stress. Strongly linked to physical responses and reactions, it can increase heart rate and blood pressure as well as create a sense of panic and overwhelming fear/dread. This neurotransmitter is similar to adrenaline and is felt to set threshold levels to stimulation and arousal. Emotionally, anxiety and depression are related to norepinephrine levels in the brain, as this neurotransmitter seems to maintain the balance between agitation and depression.
The effect upon the target neuron is determined not by the source neuron or by the neurotransmitter, but by the type of receptor that is activated. A neurotransmitter can be thought of as a key, and a receptor as a lock: the same type of key can here be used to open many different types of locks. Receptors can be classified broadly as excitatory(causing an increase in firing rate),inhibitory(causing a decrease in firing rate), or modulatory(causing long-lasting effects not directly related to firing rate).

It depends what kind of addiction you are talking about. Some addictions, like an alcohol addiction or a crystal meth addiction, have unique characteristics like one's teeth falling out, or cirosis of the liver. However, in a broad aspect, addiction can include anti-socialism, lack of motivation/loss of goals or ambitions, extreme temper changes/mood swings, noticeable change in attitude and demeanor, and - most obviously - excessive indulgence into that which you are addicted to.
