CAPE CANAVERAL, Fla. (Reuters) – A Space Exploration Technologies Dragon cargo capsule made a parachute splashdown into the Pacific Ocean on Thursday, wrapping up a five-week stay at the International Space Station.
First, the good news: Smoking rates are down significantly in 26 states. The bad news? The use of smokeless tobacco (also known as dip, snuff or chew) is up in four states, while using both cigarettes and smokeless tobacco is up significantly in five states.
“Although overall cigarette smoking prevalence has declined significantly in recent years in many states, the overall use of smokeless tobacco and concurrent cigarette and smokeless tobacco has remained unchanged in most states and increased in some states,” summed up researchers for the Centers for Disease Control, which published the data in their weekly Morbidity and Mortality report.
From 2011 to 2013, four states showed increased smokeless tobacco use: Louisiana, Montana, South Carolina and West Virginia. Only two states — Ohio and Tennessee — exhibited decreases. In terms of total use, Massachusetts and the District of Columbia reported the lowest numbers of smokeless tobacco, at 1.5 percent, in 2013. In contrast, West Virginia reported the highest use, at 9.4 percent, with Wyoming and Montana coming in second and third, at 8.8 percent and 8 percent, respectively.

The findings are significant because past research has shown that people using both products are more addicted to nicotine and less likely to want to quit both habits than those who just smoke cigarettes. It also suggests that the public may have misperceptions about the safety of smokeless tobacco — namely, that it is a safer alternative to cigarettes — thanks to advertising campaigns.
In reality, smokeless tobacco is addictive because of the nicotine it contains, and it can cause oral, esophageal and pancreatic cancer, according to the NIH’s National Cancer Institute. It may also cause other diseases like gum disease, oral lesions and precancerous patches in the mouth called —> Read More
