[FONT=Verdana, Arial, Helvetica, sans-serif]Dunedid, New Zealand:[/FONT][FONT=Verdana, Arial, Helvetica, sans-serif] Inhaling cannabis has contrasting effects on lung function compared to smoking tobacco, according to the results of a population-based study published online in the European Respiratory Journal.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]Investigators at the University of Otago in New Zealand compared the effects of cannabis and tobacco smoke on lung function in over 1,000 adults. [/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]Researchers reported, "Cumulative cannabis use was associated with higher forced vital capacity [the volume of air that can forcibly be blown out after full inspiration], total lung capacity, functional residual capacity [the volume of air present in the lungs at the end of passive expiration], and residual volume. Cannabis was also associated with higher airways resistance but not with forced expiratory volume in 1 second [the maximum volume of air that can be forcibly blown out in the first second during the FVC test], forced expiratory ratio, or transfer factor. These findings were similar amongst those who did not smoke tobacco."[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]Authors further reported, "By contrast, tobacco use was associated with lower forced expiratory volume in 1 second, lower forced expiratory ratio, lower transfer factor, and higher static lung volumes, but not with airways resistance."[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]They concluded, "Cannabis appears to have different effects on lung function to those of tobacco."[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]A previous study conducted by the University of California at Los Angeles and published in the American Journal of Respiratory & Critical Care Medicine reported that long-term, habitual marijuana use was not associated with a decline in lung function compared to non-smokers.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]Most recently, investigators at the University of British Columbia reported in April in the journal of the Canadian Medical Association that marijuana inhalation "was not associated with an increased risk of respiratory symptoms or COPD (chronic obstructive pulmonary disease)."[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]In 2007, a meta-analysis published by researchers at Yale University reported that the smoking of cannabis, even long-term, was not associated with a decline in pulmonary function.[/FONT]

Dunedin not Dunedid , This seems a bit fishy only because no one that far down in the south island can grow and its really hard to obtain marijauna way down there ! I think they should also test 1000 people from Dunedin that did'nt smoke marijauna and they will realise that its the thin cold air that is causing this situation . After all that city is Knee Deep in snow for 4 months of the year and summer temps might reach 55 F on a good year and it seems odd having Investigators at the University of Otago in New Zealand ! They are usally what we call Glorified cops ! Peace and take care !
