Yeah REVJP I read that article too. what it doesn't say is that Marijuana smokers generally dont smoke nearly as much as typical tobacco smokers do and not as constantly. Whereas a typical "pack a day" smoker will not inhale each time as much as a marijuana smoker the actual influence of all that nicotine on their system is far more powerful.
Of course the marijuana smoker is usually in total denial about the carcinogenic aspects of the Marijuana smoke, claiming that his smoke is not harmful at all (not true at all.)

Numerous studies have shown marijuana smoke to contain carcinogens and to be an irritant to the lungs. In fact, marijuana smoke contains 50 to 70 percent more carcinogenic hydrocarbons than tobacco smoke. Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which further increases the lungs’ exposure to carcinogenic smoke. Marijuana smokers show dysregulated growth of epithelial cells in their lung tissue, which could lead to cancer;8 however, a recent case-controlled study found no positive associations between marijuana use and lung, upper respiratory, or upper digestive tract cancers.9 Thus, the link between marijuana smoking and these cancers remains unsubstantiated at this time.
Nonetheless, marijuana smokers can have many of the same respiratory problems as tobacco smokers, such as daily cough and phlegm production, more frequent acute chest illness, a heightened risk of lung infections, and a greater tendency toward obstructed airways. A study of 450 individuals found that people who smoke marijuana frequently but do not smoke tobacco have more health problems and miss more days of work than nonsmokers.10 Many of the extra sick days among the marijuana smokers in the study were for respiratory illnesses. |

Yeah, fair enough.
Still the least dangerous intoxicating substance

Does anyone know off-hand how many legitimate studies have been done on the harmful affect of second-hand marijuana smoke and over what period of time? Can someone post information from some of these studies that give very specific data on the studies?
For example, what time-frame did the study cover? How many times per day did the smoker partake? How often was the (second-hand) subject there while the other person inhaled/exhaled? How many times did the smoker inhale during each session and how deeply? What grade of cannabis was he/she smoking? What tests were done on the person(s) breathing in the exhaled smoke to determine whether that person suffered any ill effects?
I'm more or less just curious about the number of studies done, the findings, the amount of marijuana smoked per day on average and the period of time the stud(ies) covered.
Thanks,
Luv

The only harmful effect of second-hand marijuana smoke that I'm aware of is the potential to fail drug tests. I don't know that any actual studies have been done beyond that.

I got a kick that this was bolded:

Sounds eerily like a tobacco company's defense against the dangers of 'second hand' smoke. Since there are no studies doing much more than demonstrating a correlation between second hand smoke and cancer....
I suppose everything depends upon perspective, what one chooses to believe can be supported or unsupported by the least conclusive of proofs...
