Currently, there is no effective treatment for addiction. Our struggle to decipher the different mechanisms involved in addiction requires a proper understanding of the brain regions which promote this devastating behavior. Previous studies have shown a pivotal role for insula in cigarette smoking. In this study we investigated the change in opium consumption after CVA. </font></font></font><b><font color="#221e1f" size="1"><font color="#221e1f" size="1"><p align="justify">Methods: </p></font></font><font color="#221e1f" face="Times New Roman,Times New Roman" size="2"><font color="#221e1f" face="Times New Roman,Times New Roman" size="2"><font color="#221e1f" face="Times New Roman,Times New Roman" size="2">This study took place in three referral academic hospitals affiliated to </font></font></font><font color="#221e1f" face="Times New Roman,Times New Roman" size="2"><font color="#221e1f" face="Times New Roman,Times New Roman" size="2"><font color="#221e1f" face="Times New Roman,Times New Roman" size="2">Tehran University of Medical Sciences. Patients who suffered a CVA and were addicted to opium were recruited during their hospitalization or visit to the neurology clinic in this study. Age, sex and the route and mean amount of opium use of each patient before CVA and 1, 3 and 6 months post-CVA was asked using a questionnaire. The patients were divided into three groups based on the location of brain ischemia (insula, basal ganglia and non-insula non-basal ganglia group). </font></font></font><b><font color="#221e1f" size="1"><font color="#221e1f" size="1"><p align="justify">Results: </p></font></font><font color="#221e1f" face="Times New Roman,Times New Roman" size="2"><font color="#221e1f" face="Times New Roman,Times New Roman" size="2"><font color="#221e1f" face="Times New Roman,Times New Roman" size="2">Seventy five percent of the patients with ischemia of the insula changed the </font></font></font><font color="#221e1f" face="Times New Roman,Times New Roman" size="2"><font color="#221e1f" face="Times New Roman,Times New Roman" size="2"><font color="#221e1f" face="Times New Roman,Times New Roman" size="2">route or amount of opium use after CVA and 37.5% of them stopped opium use af</font></font></font><font color="#221e1f" face="Times New Roman,Times New Roman" size="2"><font color="#221e1f" face="Times New Roman,Times New Roman" size="2"><font color="#221e1f" face="Times New Roman,Times New Roman" size="2">ter CVA.
