Cannabis gives you the CHRONIC lung disease

everyone always says weed is harmless... just like alcohol, but studies show otherwise...

Warning over cannabis lung harm

Cannabis bundle

The impact of cannabis on the lungs depends on how it is smoked

Heavy cannabis users may be at greater risk of chronic lung disease - including cancer - compared to tobacco smokers, two studies suggest.

 

One study found a higher risk of lung cancer for those who smoked one joint a day compared with those who smoked 20 cigarettes a day over the same period.

 

Another found bullous disease - a form of emphysema - occurs 20 years earlier in cannabis smokers.

 

The studies appear in Respirology and the European Respiratory Journal.

 

Both studies come at a time when the government is considering whether to change the laws on the possession of cannabis.

 

Deep inhalation

 

The lung cancer study was conducted on 79 patients in New Zealand. The risk of the disease rose 8% for each year of smoking one joint a day, and 7% for each year of smoking a packet of cigarettes a day.

 

 

The situation is complicated in the UK as the two drugs are almost always smoked mixed together

Researchers at the Medical Research Institute of New Zealand admitted it was a small study, but said nonetheless "it shows clearly that long-term cannabis smoking increases lung cancer risk".

 

They speculated the heightened risk may be connected to the fact that the cannabis smoker inhales more deeply and for longer, increasing the amount of carbon monoxide.

 

This was also thought to be the issue in a second, smaller study of 10 patients who were treated for chronic respiratory problems at the Alfred Hospital in Melbourne.

 

All admitted intense cannabis use for at least a year. They had developed bullous lung disease, a condition where air becomes trapped in the lungs, at an average age of 41, compared to 65 for tobacco smoking patients.

 

The campaign group Transform Drug Policy Foundation said it was very difficult to separate cannabis from tobacco use as the two were so often smoked together.

 

"Variations on the 'cannabis is more dangerous than tobacco' have been emerging sporadically for several decades. Different research using different methodologies has suggested very different conclusions, making such comparisons problematic," said spokesman Steve Rolles.

 

He added that inhaling smoke from any burning object was intrinsically harmful, and that policy should focus more on educating people about the risks of taking the drug - which can be taken using other methods - in this way.

 

The British Lung Foundation said the debate about cannabis's effect on the lungs had tended to focus on the mental affects, overlooking the impact on the lungs.

 

"Many people don't know that smoking a joint is more harmful to the lungs than smoking a cigarette, as marijuana is often inhaled more deeply and held for longer," said Dr Noemi Eiser, honorary medical director of the British Lung Foundation.

 

"The New Zealand study highlights the carcinogenic properties of cannabis smoke and it is a great worry that these exist in similar or even greater proportions to tobacco smoke."

 

The UK Government may decide later this year whether it will reclassify cannabis as a class B drug, having downgraded it to a class C substance in 2004.

 

There is evidence to suggest that usage has fallen since reclassification occurred.

most people who smoke a spliff or two are fully aware of the damages.

 

more so than people who piss all their money up the wall with alcohol....

 

in my experiences as someone who knows they smoke too much and also works as a manager of a busy pub so sees piss heads all day.

FAAAAAAAAAIL.

 

You have to be a fucking moron not to realize smoking anything is bad for you. I think when people say weed is harmless its more reference to the psychological / overdose aspect, you're not gonna pawn your moms wedding ring to get a quarter. You're not gonna hit a blunt and drop dead cause you're heart is going off like you snorted lines. I mean it's very plausible to drink yourself to death from alcohol poisoning, you're not gonna smoke an ounce in a night and die. just wake up the next morning coughing some nice sticky brown phelgm.

While this is an interesting article.

 

 

The sample size is shit.

 

 

 

I have a hard time paying attention to medical research when they don't even have a sample above 100.

 

 

Plus, if one looks back this is like one against about four or five studies that have come out saying to the contrary.

 

If I can find them I will post them.

Yeah, eating it is a lot more potent and won't mess up your lungs.

 

Vaporizers are healthier, but expensive (I used to work at a place that sold Volcanoes, and they're $500 retail) and not really portable (blender sized).

 

Smoking ANYTHING is bad for you. But, try telling that to a pothead.

 

I know this sounds kind of strange coming from me, but I really encourage people to think twice about smoking/consuming pot unless they have a medical condition and have talked to a doctor about it.

an n of 79 is way too low.

how the fuck are 79 people gonna tell you anything definitive.

 

the last UK study on this used hundreds of people and showed no increase in lung cancer risk

 

and it has been shown that pot has a positive effect on decreasing psychosis

 

 

as for the cancer though:

 

Marijuana use and the risk of lung and upper aerodigestive tract cancers: results of a population-based case-control study.

 

Hashibe M, Morgenstern H, Cui Y, Tashkin DP, Zhang ZF, Cozen W, Mack TM, Greenland S.

IARC, Lyon, France.

BACKGROUND: Despite several lines of evidence suggesting the biological plausibility of marijuana being carcinogenic, epidemiologic findings are inconsistent. We conducted a population-based case-control study of the association between marijuana use and the risk of lung and upper aerodigestive tract cancers in Los Angeles. METHODS: Our study included 1,212 incident cancer cases and 1,040 cancer-free controls matched to cases on age, gender, and neighborhood. Subjects were interviewed with a standardized questionnaire. The cumulative use of marijuana was expressed in joint-years, where 1 joint-year is equivalent to smoking one joint per day for 1 year. RESULTS: Although using marijuana for > or =30 joint-years was positively associated in the crude analyses with each cancer type (except pharyngeal cancer), no positive associations were observed when adjusting for several confounders including cigarette smoking. The adjusted odds ratio estimate (and 95% confidence limits) for > or =60 versus 0 joint-years was 1.1 (0.56, 2.1) for oral cancer, 0.84 (0.28, 2.5) for laryngeal cancer, and 0.62 (0.32, 1.2) for lung cancer; the adjusted odds ratio estimate for > or =30 versus 0 joint-years was 0.57 (0.20, 1.6) for pharyngeal cancer, and 0.53 (0.22, 1.3) for esophageal cancer. No association was consistently monotonic across exposure categories, and restriction to subjects who never smoked cigarettes yielded similar findings. CONCLUSIONS: Our results may have been affected by selection bias or error in measuring lifetime exposure and confounder histories; but they suggest that the association of these cancers with marijuana, even long-term or heavy use, is not strong and may be below practically detectable limits.

i've talked to plenty of people that think smoking weed is relatively harmless as their assumption is that cigarette smoke is bad because of the artificial shit in it, which it may be.

 

this clarifies that smoke, period, is shitty for you.

 

and yeah the fact that the test size was so small in addition to there not being a distinct tobacco smoker and weed smoker group was bullshit.
