What is considered to be a drug?

Answer 1

There are many types of hallucinogenic drugs. There are several categories of hallucinogen. The three main categories of hallucinogenic drugs are the psychedelics, dissociatives and deliriants. Some famous psychedelics include LSD-25, Psilocybin, Mescaline, DMT, 2C-B and Cannabis. Some famous dissociatives include Ketamine, Dextromethorphan, Nitrous Oxide and PCP. Famous deliriants include Atropine, Scopolamine and Diphenhydramine. The psychedelic hallucinogens mostly work by affecting serotonin receptors in the brain. Dissociatives affect NMDA, Dopamine, and/or Opioid receptors. Deliriants typically affect Acetylcholine. Each of these three categories has many, many known drugs in it and there will be more discovered in the future. Some occur naturally in nature, some are created synthetically, others are modified from their natural form to become semi-synthetic. In addition, each category of hallucinogen contains drugs with distinctly different effects than the drugs from another category. Additionally, drugs of the same category can have different effects.

Answer 2

drug (n.) A substance used in the diagnosis, treatment, or prevention of a disease or as a component of a medication. drug (n.) A chemical substance, such as a narcotic or hallucinogen, that affects the central nervous system, causing changes in behavior and often addiction. drug (v.) To administer a drug to.

A simpler definition is any substance taken to alter the functioning of the body. It does not include food items when the items are consumed as food, though a number of food items do contain drugs such as caffeine and caffeine metabolites.

Answer 3

A drug, broadly speaking, is any substance that, when absorbed into the body of a living organism, alters normal bodily function.[3] There is no single, precise definition, as there are different meanings in drug control law, government regulations, medicine, and colloquial usage.[4]

In pharmacology, a drug is "a chemical substance used in the treatment, cure, prevention, or diagnosis of disease or used to otherwise enhance physical or mental well-being."[4] Drugs may be prescribed for a limited duration, or on a regular basis for chronic disorders.[5]

Recreational drugs are chemical substances that affect the central nervous system, such as opioids or hallucinogens.[5] They may be used for perceived beneficial effects on perception, consciousness, personality, and behavior.[5][6] Some drugs can cause addiction and habituation.[6]

Drugs are usually distinguished from endogenous biochemicals by being introduced from outside the organism.[citation needed] For example, insulin is a hormone that is synthesized in the body; it is called a hormone when it is synthesized by the pancreas inside the body, but if it is introduced into the body from outside, it is called a drug.[citation needed]

Many natural substances such as beers, wines, and some mushrooms, blur the line between food and drugs, as when ingested they affect the functioning of both mind and body.
