Cannabis bigger cancer risk than cigarettes!?

[Guest]

Yet another (recent) study for us to pick apart!

If anyone can find the study, that would be helpful, I can't

Here are some fun statements!

1. 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.

2. 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.

3. 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.

4. "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.

5. "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."

6. "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.



Holy crap..,.

Why??Who really gives a fuck about your studies??The one your doing with us and the multiple ones you post daily!!Do you even look at the marijuana plants?I know ya dont smoke it!!Health concerns and all,lol!

Whats to discuss?SMOKE IS HARMFUL!!I say that pulling on the bong,We are a community of SMOKERS,not students looking to debate over smokings bad parts,what do ya get extra credit at the academy for this??



Heres a little nug FOR SMOKING!!!

Go ahead, back up your statement. Wait. You can't...

Repeatedly, scientist find that cancer rates of tobacco smokers are much higher (by a factor of more than 10x) than cannabis smokers... It has further been proved that cannabinoids kill cancer cells and protect healthy ones... The myriad of articles backing this claim can all be found posted here on icmag for anyone willing to search...

Try melemede or melamede in the search bar... Robert Melamede is a cancer researcher who has researched marijuana extensively.

There is absolutely no statistical link between marijuana smoking and getting cancer...
There is a huge statistical link between Tobacco smoking and getting cancer...

You can post up all of the theories in the world about how it might be possible for cannabis smoke to be harmful, but in reality, the science indicated that cannabis/cannabis smoke is one of the least harmful substances we come into contact with daily...

The talk about cannabinoids killing cancer cells are irrelevant because those studies are using concentrated pure forms, not through methods of smoking.

Plus, I'm not interested in generalizations. I was interested in this 1 article, which just came out Jan 29th. I'm aware of current topics on cancer with MJ. In all actuality, almost every study recommends more work to be done and that it can neither be ruled in or out that MJ is connected to cancer. There simply hasn't been enough work.

That's why this article interested me, because it's new, and it shoots some very tall claims about its findings.

Are you familiar enough with all the research to make that claim? The cancer killing action of cannabinoids has to do with cannabinoids attaching to receptor sites, not with using concentrated pure forms as 'toxins'. Also... where your statement is dead wrong, Dr. Melamede actually did research the action of cannabis smoke and tobacco smoke in the throat and lungs... Guess what... Damaged cells which have the propensity to turn cancerous are kept alive by tobacco smoke, yet killed by cannabis smoke...

That's why this article interested me, because it's new, and it shoots some very tall claims about its findings.

Plus Dr Rob Melamede's research is quite specific... He's a cancer researcher, and only discovered all of these positive actions of cannabinoids incidentally through the course of his research in finding the cure...

For someone who claim's to not be interested in generalizations you sure do post alot of articles based on broad assumptions and use lost of words like almost and maybe... And you sure do overlook alod of fact, if it conflicts with what you believe to be...

Yes, the truth is that a connection cannot be ruled out... But the truth ALSO IS that no significant statistical connection has ever been made... I'm much more likely to trust in evidence than in speculation... If there was any such link as you would like us to beleive there is, then wouldn't real world statistics bear it out? Wouldn't real world research into the specifics of the issue (like Dr. Melamede's) provide data to back you up?

 

[Guest]

Yes grateful, if only you scrutinized Melamede's research as much as you did the ones you personally don't like, huh? It'd be a diff. story for sure. What I was saying though was they don't test these subjects using smoke, they do it through concentrated delivery systems. I haven't seen the research, I've seen others, but will take a look at it. Like I said, if you scrutinized the ones the fit your agenda as much as you did the others, it'd be a diff. story.......
