This source details the neurobasis of addiction, the similarities between unnatural “drug” and natural addictions to that of food, sex, and gambling. It also provides information on the evolving attitude and acceptance as pornography as a cause for addiction, as well as push-back halting this type of development. I used the an individual can become addicted to pornography side of the argument.

Naturopathic doctor Volkow Fowler: “studies of addicts show reduced cellular activity in the orbitofrontal cortex, a brain area…[relied upon]…to make strategic, rather than impulsive, decisions. Patients with traumatic injuries to this area of the brain display problems— aggressiveness, poor judgment of future consequences, inability to inhibit inappropriate responses that are similar toto those observed in substance abusers.” 

I used this source for the yes option to my question, if an individual can become addicted to pornography, as it details a specific case of a man suffering from compulsive pornography use, the similarities between compulsive pornography use and other behavioral addictions, as well as what needs to be done in order to classify pornography addiction.

Clinical studies show brain and behavioral abnormalities commonly seen in those suffering with substance abuse disorders. The patient's "Mental status examination revealed low mood and depressed affect. His thought process showed the feeling of helplessness and hopelessness regarding his inability to control his behavior. On the Hamilton Depression Rating Scale (HAM-D) he scored 9. There were no delusions or hallucinations. His judgment and insight were intact. We ruled out, Obsessive Compulsive Disorder (OCD), depression and personality disorder through serial and separate interviews of the patient and the wife.”
