The results suggest either, that the consumption in bars and restaurants is not affected by smoking bans in the long run, or, that negative revenue impacts by smokers are compensated by increasing revenues through non-smokers. Ignition safety
An indirect public health problem posed by cigarettes is that of accidental fires, usually linked with consumption of alcohol. Enhanced combustion using nitrates was traditionally used but cigarette manufacturers have been silent on this subject claiming at first that a safe cigarette was technically impossible, then that it could only be achieved by modifying the paper. Roll your own cigarettes contain no additives and are fire safe. Numerous fire safe cigarette designs have been proposed, some by tobacco companies themselves, which would extinguish a cigarette left unattended for more than a minute or two, thereby reducing the risk of fire. Among American tobacco companies, some have resisted this idea, while others have embraced it. RJ Reynolds was a leader in making prototypes of these cigarettes in 1983 and will make all of their U.S. market cigarettes to be fire-safe by 2010. Phillip Morris is not in active support of it. Lorillard (purchased by RJ Reynolds), the US 3rd-largest tobacco company, seems to be ambivalent. Gateway drug theory
The relationship between tobacco and other drug use has been well-established, however the nature of this association remains unclear. The two main theories are the phenotypic causation (gateway) model and the correlated liabilities model.
A degloving injury is a type of avulsion in which an extensive section of skin is completely torn off the underlying tissue, severing its blood supply. It is named by analogy to the process of removing a glove. Effects
Typically, degloving injuries affect the extremities and limbs; in these cases, they are frequently associated with underlying fractures. Any injury which would induce degloving of the head or torso is likely to be lethal. However, controlled facial degloving is often featured in plastic surgery. Degloving injuries invariably require major surgical interventions. Treatment options include replantation or revascularization of the degloved skins, or when these are not possible, skin grafts or skin flaps. While the preservation of the extremities and limbs is normally preferred, in some cases amputations may be advised or required. Post-operative physiotherapy is of particular importance for degloving injuries involving the hand. Other animals
Many small mammals are able to induce degloving of their tails to escape capture; this is comparable to tail autotomy in reptiles. References
