Yes snuff has calories but humans can not digest plant material, hence they can not gain weight by eating chewing tobacco.
Human behavior refers to the range of behaviors exhibited by humans and which are influenced by culture, attitudes, emotions, values, ethics, authority, rapport, hypnosis, persuasion, coercion and/or genetics.
The behavior of people (and other organisms or even mechanisms) falls within a range with some behavior being common, some unusual, some acceptable, and some outside acceptable limits. In sociology, behavior in general is characterised as having no meaning, being not directed at other people, and thus is the most basic human action. Behavior in this general sense should not be mistaken with social behavior, which is a more advanced action, as social behavior is behavior specifically directed at other people. The acceptability of behavior depends heavily upon social norms and is regulated by various means of social control. Human behavior is studied by the specialised academic disciplines of psychiatry, psychology, social work, sociology, economics, and anthropology. Agriculture
Chewing tobacco is a type of smokeless tobacco product consumed by placing a portion of the tobacco between the cheek and gum or upper lip teeth and chewing. Unlike dipping tobacco, it is not ground and must be manually crushed with the teeth to release flavor and nicotine. Unwanted juices are then expectorated (spat).
Chewing tobacco is typically manufactured as several varieties of product – most often as loose leaf (or scrap), pellets (tobacco "bites" or "bits"), and "plug" (a form of loose leaf tobacco condensed with a binding sweetener). Nearly all modern chewing tobaccos are produced via a process of leaf curing, cutting, fermentation and processing or sweetening. Historically, many American chewing tobacco brands (which were popular during the American Civil War era) were made with cigar clippings.
Dipping tobacco, traditionally referred to as moist snuff, is a type of finely ground or shredded, moistened smokeless tobacco product. It is commonly and idiomatically known by various terms—most often as dip and sometimes as rub. It is used by placing a lump or "dip" of tobacco between the lip and the gum. The act of using it is called dipping, packing or more specifically packing a lip, or packing a lipper. Dip is colloquially called "chew", "snuff", "chaw", "daps", "baccer", "spit tobacco", or "mouth tobacco", among other terms; because of this, it is sometimes confused with other tobacco products—namely chewing tobacco or nasal/dry snuff.
Science of drugs including their origin, composition, pharmacokinetics,
pharmacodynamics, therapeutic use, and toxicology.
Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
