Active ingredient in the context of "Cannabis edible"

Alcohol, sometimes referred to by the chemical name ethanol, is the active ingredient in alcoholic drinks such as beer, wine, and distilled spirits (hard liquor). Alcohol is a central nervous system (CNS) depressant, decreasing electrical activity of neurons in the brain, which causes the characteristic effects of alcohol intoxication ("drunkenness"). Among other effects, alcohol produces euphoria, decreased anxiety, increased sociability, sedation, and impairment of cognitive, memory, motor, and sensory function.

Alcohol has a variety of adverse effects. Short-term adverse effects include generalized impairment of neurocognitive function, dizziness, nausea, vomiting, and symptoms of hangover. Alcohol is addictive and can result in alcohol use disorder, dependence, and withdrawal upon cessation. The long-term effects of alcohol are considered to be a major global public health issue and include liver disease, hepatitis, cardiovascular disease (e.g., cardiomyopathy), polyneuropathy, alcoholic hallucinosis, long-term impact on the brain (e.g., brain damage, dementia, and Marchiafava–Bignami disease), and cancers; alcohol and some of its metabolites (such as acetaldehyde) are IARC group 1 carcinogens. The adverse effects of alcohol on health are most significant when it is used in excessive quantities or with heavy frequency. However, in 2023, the World Health Organization published a statement in The Lancet Public Health that concluded, "no safe amount of alcohol consumption for cancers and health can be established." In high amounts, alcohol may cause loss of consciousness or, in severe cases, death. Many governmental agencies and organizations issue alcohol consumption recommendations.

An unguent is a soothing preparation spread on wounds, burns, rashes, abrasions or other topical injuries (i.e. damage to the skin). It is similar to an ointment, though typically an unguent is oilier and less viscous. It is usually delivered as a semi-solid paste spread on the skin, and it is often oily in order to suspend the medication or other active ingredients.

During the Victorian era, the use of the unguent macassar oil on the hair became so popular that antimacassars were invented to prevent damage to furniture.

The biological activity of a pesticide, be it chemical or biological in nature, is determined by its active ingredient (AI - also called the active substance). Pesticide products very rarely consist of the pure active ingredient. The AI is usually formulated with other materials (adjuvents and co-formulants) and this is the product as sold, but it may be further diluted in use. Formulations improve the properties of a chemical for handling, storage, application and may substantially influence effectiveness and safety.

Formulation types are categorised into two-letter international formulation codes: (e.g. GR: granules), which must be used when registering a new pesticide product. Croplife maintains this list, which in the 7th update (2017) contains 65 formulation codes and 29 codes which are no longer used.

In a general sense, an ingredient is a substance which forms part of a mixture. In cooking, recipes specify which ingredients are used to prepare a dish, and the term may also refer to a specific food item in relation to its use in different recipes. Many commercial products contain secret ingredients purported to make them better than competing products. In the pharmaceutical industry, an active ingredient is the ingredient in a formulation which invokes biological activity.

National laws usually require prepared food products to display a list of ingredients and specifically require that certain additives be listed. Law typically requires that ingredients be listed according to their relative weight within the product.

"Snake oil" is a term used to describe deceptive marketing, health care fraud, or a scam. Similarly, snake oil salesman is a common label used to describe someone who sells, promotes, or is a general proponent of some valueless or fraudulent cure, remedy, or solution. The term comes from the snake oil that was sold as a cure-all elixir for many kinds of physiological problems. Many 18th-century European and 19th-century United States entrepreneurs advertised and sold mineral oil (often mixed with various active and inactive household herbs, spices, drugs, and compounds, but containing no snake-derived substances whatsoever) as "snake oil liniment", making claims about its efficacy as a panacea. Patent medicines that claimed to be panaceas were extremely common from the 18th century until the 20th century, particularly among vendors masking addictive drugs such as cocaine, amphetamine, alcohol, and opium-based concoctions or elixirs, to be sold at medicine shows as medication or products promoting health.

In the European Union, food labeling regulations also mandate that allergens such as nuts, milk, and gluten be clearly emphasized within the ingredient list to protect consumers.

A generic drug is a pharmaceutical drug that contains the same chemical substance as a proprietary drug that was originally protected by chemical patents. Generic drugs are allowed for sale after the patents on the original drugs expire. Because the active chemical substance is the same, the medical profile of generics is equivalent in performance compared to their performance at the time when they were patented drugs. A generic drug has the same active pharmaceutical ingredient (API) as the original, but it may differ in some characteristics such as the manufacturing process, formulation, excipients, color, taste, and packaging.

Although they may not be associated with a particular company, generic drugs are usually subject to government regulations in the countries in which they are dispensed. They are labeled with the name of the manufacturer and a generic non-proprietary name such as the United States Adopted Name (USAN) or International Nonproprietary Name (INN) of the drug. A generic drug must contain the same active ingredients as the original brand-name formulation. The U.S. Food and Drug Administration (FDA) requires generics to be identical to or within an acceptable bioequivalent range of their brand-name counterparts, with respect to pharmacokinetic and pharmacodynamic properties.

Methamphetamine is a central nervous system (CNS) stimulant that is primarily used as a recreational or performance-enhancing drug and less commonly as a second-line treatment for attention deficit hyperactivity disorder (ADHD). It has also been researched as a potential treatment for traumatic brain injury. Methamphetamine was discovered in 1893 and exists as two enantiomers: levo-methamphetamine and dextro-methamphetamine. Methamphetamine properly refers to a specific chemical substance, the racemic free base, which is an equal mixture of levomethamphetamine and dextromethamphetamine in their pure amine forms, but the hydrochloride salt, commonly called crystal meth, is widely used. Methamphetamine is rarely prescribed over concerns involving its potential for misuse as an aphrodisiac and euphoriant, among other concerns, as well as the availability of other drugs with comparable effects and treatment efficacy such as dextroamphetamine and lisdexamfetamine. While pharmaceutical formulations of methamphetamine in the United States are labeled as methamphetamine hydrochloride, they contain dextromethamphetamine as the active ingredient. Dextromethamphetamine is a stronger CNS stimulant than levomethamphetamine.

Both racemic methamphetamine and dextromethamphetamine are illicitly trafficked and sold owing to their potential for recreational use and ease of manufacture. The highest prevalence of illegal methamphetamine use occurs in parts of Asia and Oceania, and in the United States, where racemic methamphetamine and dextromethamphetamine are classified as Schedule II controlled substances. Levomethamphetamine is available as an over-the-counter (OTC) drug for use as an inhaled nasal decongestant in the United States and is seldom abused. Internationally, the production, distribution, sale, and possession of methamphetamine is restricted or banned in many countries, owing to its placement in schedule II of the United Nations Convention on Psychotropic Substances treaty. While dextromethamphetamine is a more potent drug, racemic methamphetamine is illicitly produced more often, owing to the relative ease of synthesis and regulatory limits of chemical precursor availability.

Dosage forms (also called unit doses) are pharmaceutical drug products presented in a specific form for use. They contain a mixture of active ingredients and inactive components (excipients), configured in a particular way (such as a capsule shell) and apportioned into a specific dose. For example, two products may both be amoxicillin, but one may come in 500 mg capsules, while another may be in 250 mg chewable tablets.

The term unit dose can also refer to non-reusable packaging, particularly when each drug product is individually packaged. However, the FDA differentiates this by referring to it as unit-dose "packaging" or "dispensing". Depending on the context, multi(ple) unit dose may refer to multiple distinct drug products packaged together or a single product containing multiple drugs and/or doses.

An elixir is a sweet liquid used for medical purposes, to be taken orally and intended to cure one's illness. When used as a pharmaceutical preparation, an elixir contains at least one active ingredient designed to be taken orally.
