Cannabis use induces a variety of acute psychological and physiological effects that vary in intensity and duration according to the dose, the route of administration, and the degree of tolerance in the user. Acute psychological effects include euphoria (“high”), relaxation, and sedation (usually desired by persons who use cannabis recreationally), increased appetite (“munchies”) and impaired short-term memory, concentration, and psychomotor coordination. Some people experience increased anxiety, panic attacks, or paranoia, especially at higher doses. Psychotic symptoms, such as perceptual alterations, hallucinations, and delusions, are less common. Acute physical effects include impaired motor coordination, slurred speech, dry mouth, conjunctival injection (“red eye”), tachycardia, orthostatic hypotension, and horizontal nystagmus. Smoked cannabis induces cough, wheezing, and dyspnea; increases sputum production; and exacerbates asthma.

Diagnostic Criteria for Catatonia
DSM-5 Criteria for Tobacco Use Disorder
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), provides criteria for the diagnosis of tobacco use disorder, which falls under the category of substance-related and addictive disorders.
Diagnostic Criteria for Orthorexia
Orthorexia nervosa describes a pathological obsession with proper nutrition that is characterized by a restrictive diet, ritualized patterns of eating, and rigid avoidance of foods believed to be unhealthy or impure. Although prompted by a desire to achieve optimum health, orthorexia may lead to nutritional deficiencies, medical complications, and poor quality of life.
Diagnostic Criteria for Compulsive Sexual Behavior Disorder (CSBD)
Compulsive sexual behavior disorder (CSBD) is currently defined as an impulse control disorder and “characterized by a persistent pattern of failure to control intense, repetitive sexual urges and behaviors” where an individual (1) devotes excessive time to sexual activities to the point of neglecting health, personal care, interests, and responsibilities, (2) experiences diminished control manifest by multiple unsuccessful efforts to reduce sexual behavior, (3) continues sexual activity despite adverse consequences, (4) continues engagement in sexual behavior even when little or no satisfaction is derived, and (5) experiences significant distress or impairment across life domains or important areas of functioning. The classification also cautions, “Distress that is entirely related to moral judgments and disapproval about sexual impulses, urges, or behaviors is not sufficient to meet this requirement.” Additionally, paraphilic disorders are exclusionary.
Diagnostic Criteria for Premenstrual Dysphoric Disorder (PMDD)
The American Psychiatric Association (APA) focuses predominantly on psychiatric symptoms in its diagnostic criteria for premenstrual dysphoric disorder (PMDD). Symptoms can occur anytime between menarche and menopause.
DSM-5 Diagnostic Criteria for Panic Disorder
Panic Disorder (PD) is characterized by episodic, unexpected panic attacks that occur without a clear trigger. Panic attacks are defined by the rapid onset of intense fear (typically peaking within about 10 minutes) with at least four of the physical and psychological symptoms in the DSM-5 diagnostic criteria.
Hamilton Depression Rating Scale (HAM-D)

DSM-5 Diagnostic Criteria for Opioid Use Disorder
Opioid analgesics (termed opioids in this report) are a class of drugs commonly prescribed to treat moderate to severe pain. Opioids include drugs available by prescription such as oxycodone, hydrocodone, codeine, morphine, and fentanyl. Opioids also include illicit substances such as heroin and fentanyl. Although often prescribed to control pain, opioids may also produce feelings of euphoria and sedation which may lead to misuse of opioids resulting in opioid use disorder.
DSM-5 Diagnostic Criteria for Dyspraxia/Developmental Coordination Disorder
Developmental Coordination Disorder (DCD) is often characterized as a skill acquisition deficit disorder.
