Smoking said to damage the body in minutes

Smoking damages the body in minutes rather than years, according to research in the US.

The report, published in Chemical Research in Toxicology, shows that chemicals which cause cancer form rapidly after smoking.

Scientists involved in the small-scale study described the results as a stark warning to people considering smoking.

Anti-smoking charity Ash described the research as “chilling” and as a warning that it is never too early to quit.

The long term impact of smoking, from heart disease to a range of cancers, are well known. This study suggests the damage begins just moments after the first cigarette is smoked.

Faster than you might think

The researchers looked at the level of chemicals linked with cancer, polycyclic aromatic hydrocarbons (PAH), in 12 patients after smoking.

A PAH was added to the subject’s cigarettes, which was then modified by the body and turned into another chemical which damages DNA and has been linked with cancer.

The research shows this process only took between 15 and 30 minutes to take place.

Professor Stephen Hecht, from the University of Minnesota, said: “This study is unique, it is the first to investigate human metabolism of a PAH specifically delivered by inhalation in cigarette smoke, without interference by other sources of exposure such as air pollution or the diet.

The results reported here should serve as a stark warning to those who are considering starting to smoke cigarettes.”

Martin Dockrell, director of policy and research at Ash (Action on Smoking and Health), said: “Almost everybody knows that smoking can cause lung cancer.

“The chilling thing about this research is that it shows just how early the very first stages of that process begin – not in 30 years but within 30 minutes of a single cigarette for every subject in the study.

“The process starts early but it is never too late to quit and the sooner you quit the sooner you start to reduce the harm.”

The research was funded by the US National Cancer Institute.

  1. Have you ever been to a cookout or a campfire or just been alive and breathed?

    If you answered yes then your not alone all of us breathe in these PAH’S everyday of our lives just from the air itself!

    Basically these supposed researchers didnt bother to do a comparison group of
    campers or 4th of july family cookout victims of PAH’s.

    Remeber the grilled food scare of burned food causing cancer…pah’s again same thing diferent route…..

    But they would have found the same genetic changes in these same folks.

    Super doped levels of non-toxic phenanthrene……the stuff shows up in 15-30 minutes when tested……thats just proof positive of an immune system working properly!!!

    epa.gov/osw/hazard/wastemin/minimize/factshts/phenanth.pdf

    HUMAN TOXICITY………PAH’s leave the body within days in urined and feces

    exposure from everywhere………theres no way they could have stopped exposure from other sources……they gave the folks super doses to try and show genetic changes which they already knew to happen at super high doses………they chose this phenanthrene because it doesnt harm anyone………what they got was what they already knew was going to happen as its been know for decades……….remember dose makes the poison and they spun this one using mega doses to show genetic changes that they knew would happen at such high doses already……..

    PAH’s are in such low concentrations they can hardly detect them .They got like 144 ng benzo[a]pyrene per cigarette converted according to potency equivalency factors (PEFs).

    Fron littlewood and fennels toxic study for osha pels………..

    All this is in a small sealed room 9×20 and must occur in ONE HOUR.
    For Benzo[a]pyrene, 222,000 cigarettes.

    They knew the outcome before they did the study…….They used common science to spin another headline is all thats happened…….

    They said they gave them 10ug a day………..

    1 nanogram equals a billionth of a gram
