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.
Smoking among teenagers is an issue that affects countries worldwide. While not every culture views youth smoking as an issue that needs to be addressed, the U.S. has taken drastic measure in an attempt to reduce and eventually eliminate use of tobacco products among teens. 90% of smokers are estimated to have begun smoking before the age of 20, therefore it is necessary to reduce the number of youths who start smoking before this age in order to reduce the total number of smokers. When the tobacco industry first began to target this new youth demographic, they did so in an entirely non-discreet method (for example through the use of characters that mimic cartoons). Once they began to experience resistance from the public they took a more subdued approach by using anti-tobacco advertisements to actually raise awareness of tobacco products in youths and to increase their desire to smoke. Not all tobacco advertisements are harmful though. Studies have been done to understand what factors make an advertisement more effective and more readily internalized by youths. Advertisements that follow these criteria have been shown to actually decrease the likelihood of youth smoking. In order to prevent a continued and growing pattern of youth smoking, it is necessary to recognize what social factors influence teens so that preventative measures can be determined. While youth smoking may be viewed more or less negatively in different nations, it remains an issue regardless of how societies perceive it. Tobacco industries have tailored their messages to apply overseas and have encountered less restrictive legislation making advertising abroad highly influential to the targeted audience.
