Marijuana doesn't harm lung function, study found
Boston.com ^ | January 11, 2012 | Lindsey Tanner

Posted on 01/11/2012 9:29:52 AM PST by Hemingway's Ghost

CHICAGO—Smoking a joint once a week or a bit more apparently doesn't harm the lungs, suggests a 20-year study that bolsters evidence that marijuana doesn't do the kind of damage tobacco does.

The results, from one of the largest and longest studies on the health effects of marijuana, are hazier for heavy users -- those who smoke two or more joints daily for several years. The data suggest that using marijuana that often might cause a decline in lung function, but there weren't enough heavy users among the 5,000 young adults in the study to draw firm conclusions.

Still, the authors recommended "caution and moderation when marijuana use is considered."

I smoked pot for long enough to know that it does harm the lungs. Only a moron would believe otherwise.

I would think any smoke inhaled would be harmful to some extent. If legalised, people that really wanted MJ, could grow enough so they could incorporate it into their food.

Dang, that’s a relief. Now I don’t have to cut back to 20 joints a day. ;-)

20 year study? Big deal. I know a few 50 year studies. They’re mostly Democrats, so the empirical evidence doesn’t look good for the brain.

Smoking a tobacco cigarette once or twice a week won’t kill you either. Daily, another story.

From the article:

It’s not clear why that is so, but it’s possible that the main active ingredient in marijuana, a chemical known as THC, makes the difference. THC causes the “high’’ that users feel. It also helps fight inflammation and may counteract the effects of more irritating chemicals in the drug, said Dr. Donald Tashkin, a marijuana researcher and an emeritus professor of medicine at the University of California, Los Angeles. Tashkin was not involved in the new study.

Study co-author Dr. Stefan Kertesz said there are other aspects of marijuana that may help explain the results.

Unlike cigarette smokers, marijuana users tend to breathe in deeply when they inhale a joint, which some researchers think might strengthen lung tissue. But the common lung function tests used in the study require the same kind of deep breathing that marijuana smokers are used to, so their good test results might partly reflect lots of practice, said Kertesz, a drug abuse researcher and preventive medicine specialist at the Alabama university.

....

The analyses showed pot didn’t appear to harm lung function, but cigarettes did. Cigarette smokers’ test scores worsened steadily during the study. Smoking marijuana as often as one joint daily for seven years, or one joint weekly for 20 years was not linked with worse scores. Very few study participants smoked more often than that.

Like cigarette smokers, marijuana users can develop throat irritation and coughs, but the study didn’t focus on those. It also didn’t examine lung cancer, but other studies haven’t found any definitive link between marijuana use and cancer.

Judging from Ron Paul voters, brain function may be another matter.

Are there any studies telling us how much damage is done by smoking one cigarette a week? If not, this is no comparison.

It’s not the lung function you worry about with long term marijuana use. I had some friends who smoked daily for years. Their memories suck now. Watching my father slide into alzheimer’s, I’m starting to see just how important one’s brain is. I’m sure it’s fun to get high but it’s also nice to have some brain left when you’re older. Be careful with fat soluble drugs, people.

From my college days, I do not remember anyone smoking one joint a week. No one was drinking one beer or smoking one cigarette either. What a bunch of crap. This is a study from the same people who want outdoor smoking bans because second hand smoke will give you instant cancer.

"The dose makes the poison." Many things that harm us at a certain level of exposure do us precisely zero harm below some nonzero limit, as the body repels or counteracts the potential harm.

“I smoked pot for long enough to know that it does harm the lungs. Only a moron would believe otherwise.”

Logically I would agree. Pot does not have a filter and smoke seems like smoke to me (but hey, I’m not a doctor).

I think smoking is a disgusting habit and I don’t like anything about it but... if someone wants to smoke it’s their business. The way we treat smokers today is a crime.

In our society today, smoking pot is viewed more favorably than smoking cigarettes!

Second hand cigarette smoke kills everything within a 50 mile radius but try the second hand smoke gambit if you ever get caught in a drug screen and see how well it works.

This crap is worse than the global warming scam.

Turns out, on further analysis, that it did cause lung damage, but the researchers “just forgot, man”, while taking care of a bout of the munchies.

Well, that's the thing. Different substances/different activities associated with those substances. People who smoke cigarettes tend to smoke multiple cigarettes throughout the day; sometimes as much as multiple packs (20 cigs) per week. Even heavy MJ smokers don't approach that level. Nowhere near it.

Pile it higher and deeper. This "study" talks about one a week... find me a cigarette smoker who partakes once a week. The comparison is absolutely laughable on its face.

Any smoke, including that from wood fire cooking can and does cause lung damage. This "study" is agenda-driven B.S. pandering to those too stoned to grasp reality and those hoping to score big paydays trafficking pot if it were legalized.

According to the Substance Abuse & Mental Health Services Administration, 4.2% of Americans smoke more than once a year but less than once a month - so it's not hard to believe that some smoke only once a week.
