DUH..theres no filter on a joint...but at least theres no chemicals like tar and other crap pumped in it...and people that smoke cigs smoke a pack a day...compared to a joint or two at most a day. my favorite quotes are the old guy saying "others do it, it doesn't affect me so who cares" and the old lady.."thats wonderful if they are enjoying it, why not"

from the article zeth_rb links:

experts at the Medical Research Institute of New Zealand

Who? The article neither states who they are, nor in which peer-reviewed scientific journal the research was published.

A quick tour of the MRINZ website finds this tidbit:

1. The respiratory effects of marijuana smoking

This study utilised the latest advances in CT scanning technology and respiratory physiology testing to determine the effects of cannabis smoking on pulmonary structure, function and symptoms. It identified that cannabis smoking had profound effects on the lung, causing symptoms such as cough, wheezing and chest tightness, and airways obstruction resulting in hyperinflation, and reduced lung density. For the first time, the dose equivalence between cannabis and cigarettes in causing lung damage was determined. This analysis identified that one cannabis joint had similar adverse effects on the lung as between 2.5 and 5 tobacco cigarettes. This finding has major public health significance.


Note that no publication is mentioned. Also not mentioned is the method of subject inclusion in the study, or the methods used to determine the conclusions (what raw data was collected and how it was analyzed). And a search of their publication's page turns up nothing with marijuana or cannabis.

And last but not least, the article also points out that, "The study found only those who smoked tobacco suffered from the crippling lung disease emphysema...."
