Substance Use Disorder

Substance use disorder is the persistent use of drugs despite substantial harm and adverse consequences. Substance use disorders are characterized by an array of mental/emotional, physical, and behavioral problems such as chronic guilt; an inability to reduce or stop consuming the substance(s) despite repeated attempts; driving while intoxicated; and physiological withdrawal symptoms. Drug classes that are involved in SUD include: alcohol; caffeine; cannabis; phencyclidine and other hallucinogens, such as arylcyclohexylamines; inhalants; opioids; sedatives, hypnotics, or anxiolytics; stimulants; tobacco; and other or unknown substances.

Causes

 

The exact cause of substance use disorder is not known. A person’s genes, the action of the drug, peer pressure, emotional distress, anxiety, depression, and environmental stress can all be factors.Many who develop a substance use problem have depression, attention deficit disorder, post-traumatic stress disorder, or another mental problem. A stressful or chaotic lifestyle and low self-esteem are also common.Children who grow up seeing their parents using drugs may have a high risk of developing substance use problem later in life for both environmental and genetic reasons.
