Here we dont have strong law to ban people smoking in public. I hate smokers! Almost everyday I have been exposed to the poison because most of people surrounding me are smokers. And, they don't have a shame because smoking here is still very popular activity. I once warned a smoker, and he just got offended. How strange it is. I wish people here could behave! Smokers, I know, you are all are stubborn. But, you dont just harm your lif ebut my life and others too! I hate smokers!!

Smoking not good for the brain - study | News.com.au
THE tobacco industry worked for two decades to skew research into smoking and Alzheimer's disease, to promote the wrong belief it could prevent the degenerative condition, a review of research has found.
US-based scientists have reviewed more than 40 research papers published since 1984, to highlight those with industry links which also suggested smoking could be good for the brain.
A quarter of the papers were found to have industry influence - either through direct funding or using researchers who were also consultants to the industry or who had other ties.
In many cases these relationships were not disclosed, according to the analysis, which found industry-linked papers dotted through the scientific literature up to 2003.
Professor Jurgen Gotz, from the University of Sydney's Brain & Mind Research Institute, welcomed the review, saying it should help to set the record straight on nicotine's effect on the brain.

"There have been many studies looking at the incidence of Alzheimer's disease in general, and dementia in general, and the role of nicotine," Prof Gotz said.
"Some of these studies showed, or claimed to show, that smoking, in a sense, protects from Alzheimer's disease.
"It turns out when one takes these (industry-linked) studies into consideration ... the bottom line is smoking indeed is associated with an increased risk of Alzheimer's disease."
The review, by scientists at the University of California, found the industry-linked papers tended to suggest smoking was either not a risk factor or that it protected against Alzheimer's disease.
The independent studies - which outnumbered the industry-linked studies - showed how smoking posed nearly double the risk of developing the disease.
Studies into tobacco and Alzheimer's got underway in the late 1970s in response to anecdotal reports of lower rates of the condition among older smokers.
The beneficial claim continues to circulate via the internet and occasionally it pops up in the mainstream press - including in a 2008 article published in the US' top selling Oprah Magazine.
Prof Gotz said it was time to end the myth that smoking could be good for the brain.
"This has been disproved both in humans, as studies show, and in animals and cell culture systems," Prof Gotz said.
"Nicotine ... increases the degenerative changes in the brain."
Yeah, you're right about smoking. It is a popular activity in some way, because some of the other people's peers may have influenced them in doing so, or maybe it's their form of stress relief. What if there were bans? Do you think that suggesting healthier alternatives to smoking would be a good idea? I mean, there has to be something that's close to smoking but isn't as dangerous as the real thing.
ReplyDeleteWell, you're right. Smoking is really harmful to everybody, and not just for the smoker himself, but also to those who are around him. One more reason why smoking is bad is because it's also the primary cause of teeth discoloration and even halitosis.
