President of Üsküdar University Psychiatrist Prof. Nevzat Tarhan was the guest of the live broadcast of the Söz Medyanı program broadcast on AKİT TV. Tarhan made evaluations on the subject of "Substance Use and Addiction". Emphasizing that the most important factor in the diagnosis of addiction is the loss of control, Tarhan stated that "It is not just drug addiction, there's behavioral addictions as well. This is how gambling addiction and digital addiction are formed. Even though these people do not take any substances, they have reward failure syndrome in the brain." Tarhan also pointed out that a pandemic of addiction awaits the world.
