One example of something that's addictive but isn't classified as a drug is gambling. Gambling refers to the act of betting money or something of value on an event with an uncertain outcome, often with the hope of winning more money or rewards. While gambling itself is not a substance, it can lead to a behavioral addiction known as gambling addiction or pathological gambling.
Gambling addiction is characterized by a compulsive need to gamble despite negative consequences and an inability to control the urge to do so. It can have severe effects on a person's life, including financial problems, strained relationships, and psychological distress.
Other examples of non-drug addictive behaviors may include internet and video game addiction, compulsive shopping, binge-eating, and excessive use of social media. These behaviors can trigger the release of dopamine and create a cycle of reward and reinforcement, leading to addictive patterns in certain individuals.
