Opioids, used medically for pain relief, have analgesic and central nervous system depressant effects as well as the potential to cause euphoria. Opioid use disorder (OUD) can involve misuse of prescribed opioid medications, use of diverted opioid medications, or use of illicitly obtained heroin. OUD is typically a chronic, relapsing illness, associated with significantly increased rates of morbidity and mortality.
Stimulant use disorder is a type of substance use disorder that involves the non-medical use of stimulants. It is defined in the DSM-5 as "the continued use of amphetamine-type substances, cocaine, or other stimulants leading to clinically significant impairment or distress, from mild to severe"
Problem drinking that becomes severe is given the medical diagnosis of “alcohol use disorder” or AUD. AUD is a chronic relapsing brain disorder characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences.
Mental health includes our emotional, psychological, and social well-being. It affects how we think, feel, and act. It also helps determine how we handle stress, relate to others, and make choices. Mental health is important at every stage of life, from childhood and adolescence through adulthood.
