Obsessions include intrusive thoughts, phobias, images and impulses. In this presentation we are going to present an obsessive patient who was obsessed regarding using addictive substances.

Represented case is a 27 year's old married man with no previous history of cigarette and any substance abuse or dependence. He referred to our OPD clinic in Kerman psychiatric hospital / Iran. He had recurrent and intrusive thoughts which made him anxious and reported social function problems due to his thoughts. His obsessive thoughts began when he was eighteen at that time he continuously obsessed about smoking cigarette, but when was offered one by one of his friends, he scared and destroyed it. A few years later he had recurrent obsessive thoughts a bout using and marijuana and opium and the pleasure which could be occurred then after. Since a year before his referral he had the same thought about heroin. Other than this obsessive thought, he believed in magic and referred to faith healers several times. He also thought, he should sell his properties and spend the income for buying opium and heroin. This thought decreased obviously after taking 200 mg fluvoxamine during four weeks. He never used any substance even for one time. He was not smoking at all. We concluded that addiction obsession could bea separate type of obsession. It could be a variant of obsessive impulses. Availability of substances may play a role in forming his symptom.
