F10-F19: Mental and behavioural disorders due to psychoactive substance use

The group of conditions termed as 'Mental and behavioural disorders due to psychoactive substance use' represents a range of mental and behavioural alterations that occur because of the consumption of substances which affect the mind. These substances include alcohol, opioids, cannabinoids, sedatives, cocaine, other stimulants, hallucinogens, tobacco, and volatile solvents. When these substances are used in a dangerous or harmful pattern, they alter the user's mental state, lead to impaired control, and often create a strong desire to take the substance despite harmful consequences. The symptoms depend on the type of substance and may include changes in perception, mood, consciousness, cognition, and behaviour. The extent to which the substance impacts a person's routine life, relationships, and physical health further describes the severity of the disorder.-ranging from mild to severe. This type of disorder is a result of the complex interplay of genetic, environmental, and personal factors.
