Classification i am not sure but categorisation possible

M. Spirit: Socially UNacceptable and freely available substance
Aspirin: Socially acceptable and freely available PHARMACEUTICALS.
LSD: Socially UNacceptable and CONTROLLED PHARMACEUTICALS

Answer 2

Aspirin -is a therapeutic drug
LSD & methylated- is a prohibited and addictive drug
Valium - is used too in therapy but is addictive, that is why it needs usually a doctor'r prescription
cafeine - is also an addictive substance

Drugs are classified according to their effects on people.
The usually addictive and causing drug dependence nut have some therapeutic effects are under strict prescription.

Those that have detrimentral and addictive effects are
prohibited and illegal , and could cause you imprisonment., like marijuana, cocaine, heroin, etc

All substances that enter the body are considered drugs.

Answer 3

A drug is any biological substance, synthetic or non-synthetic, that is taken for non-dietary needs. It is usually synthesized outside of an organism, but introduced into an organism to produce its action. That is, when taken into the organisms body, it will produce some effects or alter some bodily functions (such as relieving symptoms, curing diseases or used as preventive medicine or any other purposes).

Note that natural endogenous biochemicals (such as hormones) can bind to the same receptor in the cell, producing the same effect as a drug. Thus, drug is merely an artificial definition that distinguishes whether that molecule is synthesized within an organism or outside an organism. For instance, insulin is a hormone that is synthesized in the body; it is considered as a hormone when it is synthesized by the pancreas inside the body, but if it is introduced into the body from outside, it is considered as a drug.

It is a substance which is not food,[1] and which, when ingested, affects the functioning of the mind, or the body, or both. However, under the philosophy of Chinese medicine, food is also considered a drug as it affects particular parts of body and cures some diseases. Thus, food does satisfy the above definition of drug so long as ingestion of it would alter some bodily functions.

Answer 4

A drug is any chemical or organic and organic substance, synthetic or non-synthetic, that as quickly as taken into the organism's physique, will in some way regulate the purposes of that organism. This huge definition may well be taken to contain such components as foodstuff. whether extra strict purposes of the be conscious prevail in daily existence. In those circumstances the be conscious "drug" is generally used to refer especially to medicine, supplementations, entheogenic sacraments, awareness increasing or leisure drug

Answer 5

Answer 6

drug (drŭg) pronunciation
n.


Any chemical agent that affects the function of living things. Some, including antibiotics, stimulants, tranquilizers, antidepressants, analgesics, narcotics, and hormones, have generalized effects. Others, including laxatives, heart stimulants, anticoagulants, diuretics, and antihistamines, act on specific systems. Vaccines are sometimes considered drugs. Drugs may protect against attacking organisms (by killing them, stopping them from reproducing, or blocking their effects on the host), substitute for a missing or defective substance in the body, or interrupt an abnormal process. A drug must bind with receptors in or on cells and cannot work if the receptors are absent or its configuration does not fit theirs. Drugs may be given by mouth, by injection, by inhalation, rectally, or through the skin. The oldest existing catalogue of drugs is a stone tablet from ancient Babylonia (c. 1700 BC); the modern drug era began when antibiotics were discovered in 1928. Synthetic versions of natural drugs led to design of drugs based on chemical structure. Drugs must be not only effective but safe; side effects can range from minor to dangerous (see drug poisoning). Many illegal drugs also have medical uses (see cocaine; heroin; drug addiction). See also drug resistance; pharmacology; pharmacy.

Answer 7

Any chemical compound used for medicianal purposes can be considered a drug. There are naturally occuring substances such as ethanol and caffeine as well as synthetic drugs such as aspirin and amphetamines. In general the term "drug" is used for compounds that can cause addiction with emphasis on narcotics..
