HEALTH BRIEFS
Smoking Cannabis
BERLIN- It is possible to die as a direct result of smoking cannabis, new research shows.
German scientists have identified two people who died purely as a result of smoking the drug.
It was previously known that using marijuana could be fatal if was used in conjunction with other drugs –such as by triggering heart conditions or by causing cancer.
However, whether the drug could kill unaided had remained unclear, New Scientist reports.
Now, scientist at the University Hospital Düsseldorf in Germany have carried out the first full post mortem examinations on people who have died after using the drug.
The team, led by Dr. Benno Hartung, carried out 15 examinations.
They performed tests including toxicology tests and genetic tests to rule out any other causes of death.
They discovered that the deaths of two patients could not be put down to anything other than marijuana use.
Neutral Scents
MADISON USA- you might be aware of your heart pounding and even your hands shaking in times of extreme stress.
And now scientists have found that scents smelling unusual can also be an indicator of anxiety.
Human’s sense of smell is affected when we are anxious, with stress re-writing the brain so that scents don’t smell right, according g to a new study.

Previously neutral smells become unpleasant and the greater the stress, the larger the change in smell, scientist claim. Wen Li, a professor of psychology at the University of Wisconsin-Madison, used brain imaging to reveal how anxiety or stress can rewire the brain, linking centres of emotion and smell-processing to make typically benign smells foul stenches. For the study, published in the Journal of Neuroscience, subjects were made anxious by showing them disturbing pictures and text of subjects like car crashes and war.



“Social” smokers warned.
LONDON –Being a “social” smoker puts you three times more at risk of dying from heart disease, warn doctors. Just one cigarette a day can triple the risk compared with people who never smoked, says the British Heart Foundation (BHF). They say the research should be a warning to the 1.1 million “part-time” smokers in the UK who are ‘fooling themselves’ over their health. Researchers found smoking between one and four cigarettes a day significantly increased the rate of heart disease, and deaths from all causes. Lung cancer rates also went up in women who were smoking at least one cigarette a day, says the research commissioned by the charity to mark No Smoking Day next week. Yet only a quarter of part-time smokers are worried about harming their health despite getting through an average 37 cigarettes a week.
Dr. Mike Knapton, associate medical director of the BHF, said Britain’s 1.1 million part-time smokers are fooling themselves if they think the health don’t apply to them.
