HONG KONG (Reuters) - Smoking a joint is equivalent to 20 cigarettes in terms of lung cancer risk, scientists in New Zealand have found, as they warned of an "epidemic" of lung cancers linked to cannabis.

Studies in the past have demonstrated that cannabis can cause cancer, but few have established a strong link between cannabis use and the actual incidence of lung cancer.

In an article published in the European Respiratory Journal, the scientists said cannabis could be expected to harm the airways more than tobacco as its smoke contained twice the level of carcinogens, such as polyaromatic hydrocarbons, compared with tobacco cigarettes.

The method of smoking also increases the risk, since joints are typically smoked without a proper filter and almost to the very tip, which increases the amount of smoke inhaled. The cannabis smoker inhales more deeply and for longer, facilitating the deposition of carcinogens in the airways.

"Cannabis smokers end up with five times more carbon monoxide in their bloodstream (than tobacco smokers)," team leader Richard Beasley, at the Medical Research Institute of New Zealand, said in a telephone interview.

"There are higher concentrations of carcinogens in cannabis smoke ... what is intriguing to us is there is so little work done on cannabis when there is so much done on tobacco."

The researchers interviewed 79 lung cancer patients and sought to identify the main risk factors for the disease, such as smoking, family history and occupation. The patients were questioned about alcohol and cannabis consumption.

In this high-exposure group, lung cancer risk rose by 5.7 times for patients who smoked more than a joint a day for 10 years, or two joints a day for 5 years, after adjusting for other variables, including cigarette smoking.

"While our study covers a relatively small group, it shows clearly that long-term cannabis smoking increases lung cancer risk," wrote Beaseley.

"Cannabis use could already be responsible for one in 20 lung cancers diagnosed in New Zealand," he added.

"In the near future we may see an 'epidemic' of lung cancers connected with this new carcinogen. And the future risk probably applies to many other countries, where increasing use of cannabis among young adults and adolescents is becoming a major public health problem."

Too bad there's other studies out there that directly contradict this one. You have to take these things with a grain of salt.

EDIT: What I mean is that this is still unproven. Until there are consistent results from clinical trials we have no proof.

Oh, and don't try to call me a "stoner" defending my "habits". I smoke less than once a month right now.

Makes sense. Well, I have no reason to smoke weed or cigarettes, and a couple not to smoke either....hmmm

this been known for quite a while. The difference is pot is not physically addictive the way smoking is, unless its been tampered with by a scumbag drug dealer. Therefore people who smoke pot usually do it way less often than people that smoke cigarretes, if you smoke a joint once a month thats what? 2 packs a month?? thats still less than what most regular smokers do. Also it is a habit that is much easier to kick. Pretty much everyone in my family (except me but im younger than them) smoked pot at one point in their life (usually college) and havent done it since.

Many of those who indulge in smoking marijuana may smoke a joint a day, which equals the pack of cigarettes that cig smokers may smoke per day.

lol why are you guys so hell bent on attacking stoners? sounds like yall are jealous to me.

but ill be the first stoner to admit... duh! of course smoking weed will no doubt cause some sorta harm if used regularly, if you smoke ANYTHING for long enough its gonna have some adverse effects.

with that being said there are still many many variables that this "propaganda" doesent look at. not to mention there are a bunch of studies that have concluded otherwise.

just use your brain people, if you smoke a couple joints a day yeah you will not doubt be doing damage to yourself but not NEARLY as much as an addicted smoker.

I'm a stoner, and I'm not gonna shove that propaganda **** down u guys throats....

wake up and smell the ****ing coffee, everything around us can attribute to cancer. factories everywhere are destroying the air, even automobiles are, and thats a just a fraction of the stuff that pollutes the planet. every time i light a joint or pipe, I'll just thank god i'm not sucking down 2 packs a day and not living next to a factory.

I've just as much a risk of getting cancer from pot as I do going outside and breathing the air. people need to stop shunning pot smokers....its ridiculous, u might as well shun ppl who drink or smoke cigarettes because alcohol=liver failure

This guy is a dumbass. The carcinogen is not new, people have been smoking lots of weed for decades. If cannabis smoke can cause a cancer epidemic, it would have happened by now. Has it? Perhaps.

Do I care? No. I smoke the equivalent of a fat joint once every two weeks. Big deal.

yeah smoking from a joint may have more health issues than tobacco, but if cannabis were legal people wouldn't have to smoke it, it could be eaten or at the vary least smoked with a vaporizer which cures it of nearly all harmful chemicals because no actual smoke is made, stupid drug war crusaders

i didn't miss that, it was exactly what i was addressing
i can't speak for others, but its not something to do every single day, its more something to do a few times a month. this is because cigarette smokers are addicted, and pot smokers (still not speaking for everyone) are not

But yeah i just wanna keep in mind in all of this that if weed were to be eaten it would have absolutly no negative side effects. It's a proven fact and also that if we legalized it better strains would be easier to afford which would allow people who prefer to smoke it to smoke a smaller amount to get the desired effect. I don't know if any of you guys have tried authentice kush or haze strains, but one hit and ur good, there's no way u could cheef a whole joint to yourself... noobs

Incorrect.

It also harms the brain, destroying the nerve receptors that feel pleasure, as well as liquifying the section of the brain that makes decisions and solves problems. It can also destroy your memory.

there are some problems with this study 1.) they used too small a sample size, 2.) there are several studies that contradict this. also I can't find a complete copy of the study so I have no clue how exactly they came to this conclusion. The fact is that smoking anything regularly is bad for your lungs, but I'm still not convinced that weed is that bad for you
