[Addictions]

The addictive disorder is a multifactorial pathology variable in its manifestations, environmental, developmental, inheritable, neurobiological, and behavioral.

Synthesis of recent data from the literature.

Addiction is a pathology affecting decision-making, the emotional balance, the voluntary control of behaviour, not only in cases of psychoactive products use but also in behavioural dependencies. The social environment, developmental stages, and genetic factors are closely related to the vulnerability to addiction. In this article, after reviewing risk factors and neurobiology data, we will use cannabis, synthetic cannabinoids and cocaine as an example of substance use disorder.
