Smoking Marijuana Is Good For Your Lungs [Recent Study]
Another big victory for marijuana supporters this week after a study was published in the Journal of the American Medical Association which found that smoking a moderate amount of pot can actually help your lung capacity.
Researchers at University of California-San Francisco and University of Alabama at Birmingham examined 5,000 people ages 18 to 30 over a 20 year period and then collected information about each persons tobacco and marijuana smoking habits. Researchers then took measurements of a users lung capacity, specifically forced expiratory volume (FEV) which measures how much volume of air the lungs can hold along with forced vital capacity (FVC), or the speed at which a person can blow air out) at several key points during the studies entire period.
Researchers as expected found that tobacco smoking reduced lung capacity while marijuana smoking in moderate marijuana smokers improved lung capacity for both FVC and FEV levels. However the authors note that very heavy marijuana smoking still appears to decrease lung capacity.
The study’s authors state that too few of their participants were heavy smokers or heavy marijuana users to actually draw a direct connection, however moderate use of marijuana is the database showed that people who smoke a few joints per week reaped positive benefits.
The research project also found that most marijuana smokers tend to taper off their use of marijuana as they grow older while cigarette smokers tend to smoke a steady regime of cigarettes throughout their life.
In investigating why marijuana smokers increase their lung capacity the researchers believe that the way marijuana is smoked players a part. Pot smokers tend to draw smoke deep into their lungs while expanding their chest walls to accommodate for their “deep smoking” which in turn might actually strengthen lungs.

It is much safer to smoke marijuana than tobacco, but if you use edible cannabis products it is even better, and it can relieve pain.

Marijuana is the safest drug with actual benefits for the user as opposed to alcohol which is dangerous, causes addiction, birth defects, and affects literally every organ in the body. Groups are organizing all over the country to speak their minds on reforming pot laws. I drew up a very cool poster featuring Uncle Willie Nelson and The Teapot Party for the cause which you can check out on my artist’s blog at http://dregstudiosart.blogspot.com/2011/01/vote-teapot-2011.html Drop in and let me know what you think!

1) Tobacco is cancer causing largely because it delivers specific carcinogens such as NNK and NNAL that are not present in cannabis. Not all "tar" is created equal, and tobacco has some of the most carcinogenic types of tar known to science, whereas cannabis does not.

2) Cannabis (marijuana) use is associated with a DECREASE in several types of cancer… potentially even providing a protective effect against tobacco and alcohol related cancer development.
Donald Tashkin, a UCLA researcher whose work is funded by NIDA, did a case-control study comparing 1,200 patients with lung, head and neck cancers to a matched group with no cancer. Even the heaviest marijuana smokers had no increased risk of cancer, and had somewhat lower cancer risk than non-smokers (tobacco smokers had a 20-fold increased lung cancer risk). Tashkin D. Marijuana Use and Lung Cancer: Results of a Case-Control Study. American Thoracic Society International Conference. May 23, 2006.
Researchers at the Kaiser-Permanente HMO, funded by NIDA, followed 65,000 patients for nearly a decade, comparing cancer rates among non-smokers, tobacco smokers, and marijuana smokers. Tobacco smokers had massively higher rates of lung cancer and other cancers. Marijuana smokers who didn't also use tobacco had no increase in risk of tobacco-related cancers or of cancer risk overall. In fact their rates of lung and most other cancers were slightly lower than non-smokers, though the difference did not reach statistical significance. Sidney, S. et al.

This article is a joke. It is saying that smoking a small amount of pot is only beneficial because of the exercise involved in the inhalation process, not in the marijuana itself. It also says heavy users still show a decrease in lung capacity. Think of it like eating less calories vs eating the same amount of calories vs eating more calories than exercising burns. Which means stop being lazy dumb asses and just do breathing exercises for the same effect. Also read over this before you compare it to alcohol. "Study suggests pot use in early teens can harm cognitive function" the only reason alcohol is more dangerous than pot on charts is because people are irresponsible and abuse alcohol. I can have a mixed drink, Smirnoff or beer, and thoroughly enjoy the flavor and maybe even catch a harmless buzz (obviously without driving) smoke one joint and there is no leeway. You will experience the full effect of the joint itself. Trying to convince yourself that pot is good for you just proves that you need to get off your lazy ass and go to college. One more thing, they say this survey was conducted over 5000, 18-30 year-olds but they don't take into account if their samples exercise normally or do daily activities that normally increase lung capacity. The only way to conduct this experiment properly is to sit down the same 5000 people for 20 years and make them live the same exact life, to a T, to make sure that marijuana is the only factor that could change their lung capacity. I am pretty sure they didn't do that.

Imagine what use we could make of the Federal money spent towards enforcing marijuana laws.

I use to smoke marijuana….I think that it harm my heathl, but I fell happy that it is good for our lungs………..I take marijuana daily..and I want to be in goodrack……thanks researchers…
