F10-F19: Mental and behavioural disorders due to psychoactive substance use
F11: Mental and behavioural disorders due to use of opioids
Mental and behavioural disorders due to use of opioids represent a group of conditions characterized by disturbances in brain functions and behaviors brought about by the use of opioids. Opioids, a type of potent painkiller that includes drugs like morphine, hydrocodone, and fentanyl, can alter the user's mental state, mood, or behaviors when used inappropriately or for extended periods of time. Common symptoms can include slowed breathing, euphoria, confusion, poor coordination, and in severe cases, unconsciousness or even coma. With chronic use, individuals may develop physical dependence or addiction, which can lead to withdrawal symptoms when the drug use is abruptly stopped. The severity of the disorder can range from mild to severe, with acute conditions often escalating after continued use of the substances. While these disorders primarily impact the central nervous system, they can also negatively affect various other systems in the body over time.
