Email That whiff of pot that drifts your way at a rock concert or outdoor event could damage your heart and blood vessels as much as secondhand cigarette smoke does, preliminary research suggests. Blood vessel function in laboratory rats dropped by 70 percent after a half-hour of exposure to secondhand marijuana smoke -- similar to results found with secondhand tobacco smokeresearchers from the University of California, San Francisco reported Sunday. Reduced blood vessel function can increase a person's risk of developing hardened arteries, which could lead to a heart attack. Both tobacco and marijuana smoke impair blood vessel function similarly," said study senior author Matthew Springer, a cardiovascular researcher and associate professor of medicine in the university's cardiology division.
Brain tumors Secondhand smoke causes other diseases and death Secondhand smoke can be harmful in many ways. For instance, it affects the heart and blood vessels, increasing the risk of heart attack and stroke in non-smokers.
Some studies have linked SHS to mental and emotional changes, too.
For instance, some studies have shown that exposure to SHS is linked to symptoms of depression. More research is needed to better understand the link between SHS and mental health.
Most of their exposure to SHS comes from adults parents or others smoking at home. Studies show that children whose parents smoke: Some of these problems might seem small, but they can add up quickly.
Think of the expenses, doctor visits, medicines, lost school time, and often lost work time for the parent who must stay home with a sick child. Where is secondhand smoke a problem? You should be especially concerned about exposure to secondhand smoke SHS in these places: At work The workplace is a major source of SHS exposure for many adults.
The Surgeon General has said that smoke-free workplace policies are the only way to prevent SHS exposure at work. Separating smokers from non-smokers, cleaning the air, and ventilating the building cannot prevent exposure if people still smoke inside the building.
An extra bonus of workplace smoking restrictions, other than protecting non-smokers, is that they may also encourage smokers to smoke less, or even quit. In public places Everyone can be exposed to SHS in public places where smoking is allowed, such as some restaurants, shopping centers, public transportation, parks, and schools.
Public places where children go are a special area of concern. At home Making your home smoke-free may be one of the most important things you can do for the health of your family. Any family member can develop health problems related to SHS.
And think about it: A smoke-free home protects your family, your guests, and even your pets. Multi-unit housing where smoking is allowed is a special concern and a subject of research.
Tobacco smoke can move through air ducts, wall and floor cracks, elevator shafts, and along crawl spaces to contaminate units on other floors, even those that are far from the smoke. SHS cannot be controlled with ventilation, air cleaning, or by separating smokers from non-smokers.
In the car Americans spend a great deal of time in cars, and if someone smokes there, the toxins can build up quickly — even when the windows are open or the air-conditioner is on.
Again, this can be especially harmful to children.Second-hand smoke is made up of exhaled smoke from smokers. It also comes from cigarettes, cigars or pipes.
There are many effects of second-hand smoke.
One is since the organic material in tobacco doesn't burn completely, cigarette smoke contains chemical compounds, including carbon monoxi. Workers at New York City hookah bars are inhaling hazardous levels of carbon monoxide and nicotine while at work, signaling yet another breach by their employers of New York City’s anti-smoking bylaws.
This is the finding of the study, “Secondhand hookah smoke: an occupational hazard for hookah.
Secondhand smoke is associated with disease and premature death in nonsmoking adults and children (4, 5).Exposure to secondhand smoke irritates the airways and has immediate harmful effects on a person’s heart and blood vessels.
Secondhand smoke (also known as environmental tobacco smoke) is the smoke a smoker breathes out and that comes from the tip of burning cigarettes, pipes, and cigars. It contains about 4, chemicals. Secondhand smoke can be as dangerous to a dog's or cat's health as to a human's, according to new research at the University of Glasgow.
The study found family cats and dogs exposed to secondhand smoke can suffer from cancer, cell damage and weight gain. Second-hand smoke contains over chemicals and is a mix of mainstream smoke exhaled by smokers and sidestream smoke emitted from the tips of burning cigarettes. Second-hand smoke is also known as passive smoke or environmental tobacco smoke (ETS).
