Cannabis (/ˈkænəbɪs/), commonly known as marijuana (/ˌmærəˈwɑːnə/), weed, pot, and ganja, among other names, is a non-chemically uniform psychoactive drug from the Cannabis plant. Native to Central or South Asia, cannabis has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries. Tetrahydrocannabinol (THC) is the main psychoactive component of cannabis, which is one of the 483 known compounds in the plant, including at least 65 other cannabinoids, such as cannabidiol (CBD). Cannabis can be used by smoking, vaporizing, within food, or as an extract.

Cannabis has various mental and physical effects, which include euphoria, altered states of mind and sense of time, difficulty concentrating, impaired short-term memory, impaired body movement (balance and fine psychomotor control), relaxation, and an increase in appetite. Onset of effects is felt within minutes when smoked, but may take up to 90 minutes when eaten (as orally consumed drugs must be digested and absorbed). The effects last for two to six hours, depending on the amount used. At high doses, mental effects can include anxiety, delusions (including ideas of reference), hallucinations, panic, paranoia, and psychosis. There is a strong relation between cannabis use and the risk of psychosis, though the direction of causality is debated. Physical effects include increased heart rate, difficulty breathing, nausea, and behavioral problems in children whose mothers used cannabis during pregnancy; short-term side effects may also include dry mouth and red eyes. Long-term adverse effects may include addiction, decreased mental ability in those who started regular use as adolescents, heart disease, chronic coughing, susceptibility to respiratory infections, and cannabinoid hyperemesis syndrome.

Sjögren's disease (SjD), previously known as Sjögren syndrome or Sjögren's syndrome (SjS, SS), is a long-term autoimmune disease that primarily affects the body's exocrine glands, particularly the lacrimal and salivary glands. Common symptoms include dry mouth, dry eyes and often seriously affect other organ systems, such as the lungs, kidneys, and nervous system.

A hangover is the experience of various unpleasant physiological and psychological effects usually following the consumption of alcohol, such as wine, beer, and liquor. Hangovers can last for several hours or for more than 24 hours. Typical symptoms of a hangover may include headache, drowsiness, weakness, concentration problems, dry mouth, dizziness, fatigue, muscle ache, gastrointestinal distress (e.g., nausea, vomiting, diarrhea), absence of hunger, light sensitivity, depression, sweating, hyper-excitability, high blood pressure, irritability, and anxiety.

While the causes of a hangover are still poorly understood, several factors are known to be involved including acetaldehyde accumulation, changes in the immune system and glucose metabolism, dehydration, metabolic acidosis, disturbed prostaglandin synthesis, increased cardiac output, vasodilation, sleep deprivation, and malnutrition. Beverage-specific effects of additives or by-products such as congeners in alcoholic beverages also play an important role. The symptoms usually occur after the intoxicating effect of the alcohol begins to wear off, generally the morning after a night of heavy drinking.

A cannabis edible, also known as a cannabis-infused food or simply an edible, is a food item (either homemade or produced commercially) that contains decarboxylated cannabinoids (cannabinoid acids converted to their orally bioactive form) from cannabis extract as an active ingredient. Although edible may refer to either a food or a drink, a cannabis-infused drink may be referred to more specifically as a liquid edible or drinkable. Edibles are one of several methods used to consume cannabis. Unlike smoking, in which cannabinoids are inhaled into the lungs and pass rapidly into the bloodstream, peaking in about ten minutes and wearing off in a couple of hours, cannabis edibles may take hours to digest, and their effects may peak two to three hours after consumption and persist for around six hours. The food or drink used may affect both the timing and potency of the dose ingested.

Most edibles contain a significant amount of THC, which can induce a wide range of effects, including: heightened sensory perception, relaxation, sleepiness, dizziness, dry mouth, euphoria, depersonalization and/or derealization, hallucinations, paranoia, and decreased or increased anxiety. THC-dominant edibles are consumed for recreational and medical purposes. Some edibles contain a negligible amount of THC and are instead dominant in other cannabinoids, most commonly cannabidiol (CBD). The main characteristic of cannabis edibles is that they take longer to affect users compared to smoked cannabis.

Atropine is a tropane alkaloid and anticholinergic medication used to treat certain types of nerve agent and pesticide poisonings as well as some types of slow heart rate, and to decrease saliva production during surgery. It is typically given intravenously or by injection into a muscle. Eye drops are also available which are used to treat uveitis and early amblyopia. The intravenous solution usually begins working within a minute and lasts half an hour to an hour. Large doses may be required to treat some poisonings.

Common side effects include dry mouth, abnormally large pupils, urinary retention, constipation, and a fast heart rate. It should generally not be used in people with closed-angle glaucoma. While there is no evidence that its use during pregnancy causes birth defects, this has not been well studied so sound clinical judgment should be used. It is likely safe during breastfeeding. It is an antimuscarinic (a type of anticholinergic) that works by inhibiting the parasympathetic nervous system.
