Marijuana Use Doesn’t Increase Risk for Adverse Lung Function, May Reduce Emphysema

Marijuana Use Doesn’t Increase Risk for Adverse Lung Function, May Reduce Emphysema
The long-term use of marijuana isn’t associated with a decrease in lung function, and may reduce the risk of emphysema, according to a new study published by the journal Chronic Obstructive Pulmonary Diseases.

For the study, researchers examined the relationship between the long-term use of marijuana and lung health in 2,300 patients ages 40 to 80.“This cross-sectional analysis of participants enrolled into the SPIROMICs cohort was performed to investigate the relationships between marijuana use and pulmonary function and symptoms”, states the study, which notes that “Those enrolled were carefully screened and recruited based on tobacco use history and spirometric function”.According to researchers; “Neither current nor former marijuana use was associated with increased risk of cough, wheeze, or chronic bronchitis when compared to never marijuana users after adjusting for covariates”. Both current and former marijuana use “was associated with significantly less quantitative emphysema”. In agreement with other published studies, researchers “also did not find that marijuana use was associated with more obstructive lung disease.”The full text of the study can be found by clicking on the top link. It was conducted by researchers from the following institutions:

National Jewish Health, Denver, Colorado
Department of Epidemiology, Colorado School of Public Health, University of Colorado Anschutz Medical Campus, Aurora
Division of Pulmonary and Critical Care Medicine, David Geffen School of Medicine, University of California at Los Angeles
Division of Pulmonary, Critical Care, Sleep and Allergy, Department of Medicine and Cardiovascular Research Institute, University of California San Francisco, School of Medicine, San Francisco
Departments of Radiology, Medicine and Biomedical Engineering, University of Iowa, Iowa City
University of Utah Health Sciences Center, Salt Lake City

The facts are in cannabis is not harmful to your lungs. Too bad reefer madness people or narcs don't like or accept facts. :bigblunt:

An anti-inflammatory, and tokers will usually go out of their way to remove the irritating qualities.

There are limitations to the interpretation of the results from this study. Mainly, this population is non-random and was recruited based on tobacco smoking history. Although we adjusted for tobacco use and excluded never tobacco smokers, it is still unclear if long-term heavy marijuana smoking results in significant risk of respiratory symptoms, lung obstruction, inflammation, or emphysema. The strong associations between tobacco smoking and adverse respiratory health may be masking effects of marijuana use. However, contemporaneous to the legalization of marijuana in many states, there has also been an exponential increase in the potency of tetrahydrocannabinol (THC) in marijuana from 3% to now 30% or more. Thus, marijuana smoke exposure should be expected to decrease as potency increases since users would need to smoke less to achieve the desired level of intoxication. Moreover, there may be fewer individuals who have heavy marijuana smoking exposure, unlike many tobacco smokers for whom it is not uncommon to smoke 40-60 cigarettes per day. Another limitation is that marijuana was an illegal, schedule 1 substance in most of the United States at the time our participants were recruited. This may have biased against honest disclosure of marijuana use. Additionally, marijuana exposure can be more difficult to quantify because of sharing, differences in dosing and inhalation techniques, and methods to consume or use marijuana (e.g., vaping, dabbing, edibles). These newer methods of exposure may not have been fully quantified in the SPIROMICS cohort; however, the advanced age of the cohort suggests that smoking was the predominant marijuana delivery method.18,19 The analyses presented here adjust for joint years. It is difficult to quantify joint years since one joint or bowl is not universally comparable. This may explain why joint years was not shown to be a predictive covariate in any of our statistical models of current marijuana use status and pulmonary outcomes. Finally, marijuana and its effect on lung function was not the primary aim of the SPIROMICS study and there were only 192 active users. Although these results were able to detect differences in lung function and phenotypes among marijuana use groups, these results are not generalizable to a healthy adult population. There may be no to little increased risk of marijuana use for a further increase in respiratory symptoms or adverse effects on lung function among those with a history of concomitant tobacco use.

I think it's funny when people say their is no risk to smoking marijuana.

All plant matter produces nitrogen dioxide upon burning. If you don't know what nitrogen dioxide is, look it up.

It's pretty simple, really.

Please , you have to be a complete moron to believe smoking anything isn't bad for you , no offense but get a grip people

There are too many peer reviewed studies that point to at the very least inflammation due to marajuana smoking .

Wishful thinking is thinking it won't harm you , not trying to break plates here but that's truth

Stress from without toking could be to some degree harmful for what it's worth

The really important facts were that spatial relationships had ceased to matter very much and that my mind was perceiving the world in terms of other than spatial categories. At ordinary times the eye concerns itself with such problems as where? — how far? — how situated in relation to what? In the mescaline experience the implied questions to which the eye responds are of another order. Place and distance cease to be of much interest. The mind does its perceiving in terms of intensity of existence, profundity of significance, relationships within a pattern."
