There are behavioral addictions, such as gambling or gambling. In these cases, the brain shows changes very similar to those of substance addictions: the reward system is altered, the need to repeat the behavior increases, and a loss of control appears. Therefore, the person can continue gambling even when there are already serious consequences: family problems, work or debts.
The fact that there is no substance does not mean that there is no addiction.
