Smoking marijuana may not harm lungs

Smoking pot is legal here, and there has been no rise in use of other drugs. Not interested in using it though, would only use it if necessary for my health. I like wasting money on other things than pot.

One thought is that the THC in marijuana smoke may selectively kill off old, decrepit lung cells that are the most likely to become cancerous, possibly explaining how some studies show a lower incidence of lung cancer in people who only smoke pot.

Yep, it's interesting that cannabis contains significantly more tar than tobacco and yet...

While cannabis smoke has been implicated in respiratory dysfunction, including the conversion of respiratory cells to what appears to be a pre-cancerous state [5], it has not been causally linked with tobacco related cancers [6] such as lung, colon or rectal cancers. Recently, Hashibe et al [7] carried out an epidemiological analysis of marijuana smoking and cancer. A connection between marijuana smoking and lung or colorectal cancer was not observed. These conclusions are reinforced by the recent work of Tashkin and coworkers [8] who were unable to demonstrate a cannabis smoke and lung cancer link, despite clearly demonstrating cannabis smoke-induced cellular damage.

Furthermore, compounds found in cannabis have been shown to kill numerous cancer types including: lung cancer [9], breast and prostate [10], leukemia and lymphoma [11], glioma [12], skin cancer [13], and pheochromocytoma [14]. The effects of cannabinoids are complex and sometimes contradicting, often exhibiting biphasic responses. For example, in contrast to the tumor killing properties mentioned above, low doses of THC may stimulate the growth of lung cancer cells in vitro [15].

Smoke from tobacco and cannabis contains many of the same carcinogens and tumor promoters [20,21]. However, cannabis and tobacco have additional pharmacological activities, both receptor-dependent and independent, that result in different biological endpoints. Polycyclic aromatic hydrocarbons found in smoke are pro-carcinogens that are converted to carcinogens by the enzymatic activity of the cytochrome P4501A1 oxidase protein (CYP1A1 gene product). Benzo [a] pyrene is converted to its carcinogenic metabolite diol epoxide, which binds to specific hyper-mutable nucleotide sequences in the K-ras oncogene and p53 tumor suppressor [22]. Recent work by Roth et al. demonstrates that THC treatment of murine hepatoma cells caused a dose dependent increase in CYP1A1 gene transcription, while at the same time directly inhibiting the enzymatic activity of the gene product [23]. Thus, despite potentially higher levels of polycyclic aromatic hydrocarbons found in cannabis smoke compared to tobacco smoke (dependent on what part of the plant is smoked), the THC present in cannabis smoke should exert a protective effect against pro-carcinogens that require activation. In contrast, nicotine activates some CYP1A1 activities, thus potentially increasing the carcinogenic effects of tobacco smoke [24].

Not if you are Carl Sagan.

It’s hard to argue for pot slowing you down when you look at Carl Sagan’s record. Apparently a confirmed and admitted stoner, among his many achievements are a Pulitzer Prize, an Emmy, a best-selling novel, as well as more than 500 science papers and articles. He was a founding member of the Planetary Society, and he won a pipe load of scientific awards. Hardly surprising, he is said to have believed in the validity of stoned insights. I believe in them too, it’s just that Carl’s revolved around the origins of the cosmos, not which bagel store is open at 3 in the morning.

I'm 31, I've been smoking weed since 14 and apart from some minor dabbling with Class A's in my late teens and early 20's, I've never desired anything more / stronger.

If it is a gateway drug, it's because criminalisation drives the weak and the vulnerable to drug dealers who have an interest in upselling to something more expensive and more addictive.
 
most smoke it with tabacco from sigarettes.

Anyway, Smoking weed does increase the chance that psychosis might kick in at an early age..

Good news though for pure smokers. I loved that shit when i was younger.
 
Cool, when there's a new study we can talk about the Mary J again? ;) Didn't know Sagan was a stoner. Makes sense though.
 
The whole 'gateway' concept is so silly, obviously if you're using hard drugs then you would have not had a problem with using a far less harmful drug at an earlier point. I mean is there anyone out there that went from straight edge to crack?
 
put a lab coat on a monkey and you it would be more qualified to be called a "scientist" than some of the morons who ran this study. Additionally I am curious as to where their funding came from.
 
What I don't understand is the anger some people are presenting when people are proposing that marijuana isn't as harmful as commonly believed.

They know they're missing out on something so they're happier when they believe that something is the devil's own armpit-hair.
 
I read this story on AP earlier, it was that if you only smoke like once a week or something then it's going to make a negligible impact.

But that's first of them all a pretty occasional pot smoker, not one who's going to be super concerned about potential long term health effects. Second I don't think I've ever known anyone who smokes the equivalent of like a pack a day of weed so it's a lot harder to make any one to one comparisons between cigarettes and weed. Especially as the way it affects you is so different that obviously nobody could smoke like 20 grams in a day without being a vegetable.

If you want to make weed finally legalized, accept all the negative health effects and let people make their own mind on whether they want it legalized or not. I'm not knocking the scientists, they did the research they got the results.

But journalists putting outrageous titles about how there's no negative health effects are just being disingenuous, and this thread title is an example of that. Like as though bronchitis is uncommon for pot smokers.

I remember I smoked, then started doing crack and sucking dick . By doing crack and sucking dick i mean eating in-n-out and listening to dubstep.
 
I think this applies if you smoke it without tobacco which i don't. I live in Amsterdam and the weed here is so strong you have mix it with tobacco. I smoke it almost everyday. Everything has a bad side after a while. With weed it's that you get lazy and don't want to do things.

edit: To the person who said that weed is a gateway drug that is absoluty not true. I smoke now for 5 or 6 years and never used a harddrug in my live.

You know, I've been really skeptical on this issue for a very long time.

However, about a month ago I decided to once and for all to try to keep a very open mind and look into the other side and genuinely try to understand their point of view.

And if my mind changes on the subject, so be it.

On a recommendation, it was suggested that I watch Discovery Channel's "Weed Wars" as it supposedly shows what the legalization movement is all about.

I caught an episode and, though I am always careful of "Hollywoodization," it seemed to be the real deal and quite a professional business that truly wants to give comfort to sick people through the sales of cannabis.

There was a girl in a wheelchair that genuinely seemed to respond to their medicine for her affliction and, while my initial knee-jerk thought was "placebo-effect," I thought, well even so if that helps her and others like her then why not?

Or perhaps, it REALLY does work for pain for crying out loud.

Then one of their "buyers" gets caught stealing money from the clinic.

Okay, whatever, thieves are everywhere regardless of the circumstances.

But when he was confronted as to why he stole, he says it was to buy vicodin to help with his pain from an accident.

A professional marijuana buyer, with access to all the weed he could ever want, working in a clinic that provides product to people who use it to manage pain, STEALS MONEY TO BUY VICODIN FOR PAIN RELIEF.

That's when I realized that we are all being HAD.
 
^^ The only argument you need for legalization of this or any other drug is that it's our bodies and we should have complete control over it, especially as adults. Legalization supporters wouldn't be forced to jump through hoops if people would stop forcing their lifestyles onto others.

oh come on, pot is incidental to his genius. He had a shitload of knowledge beforehand, which smoking pot helped him think about. It enhances what is already there. That he puts it so generally might be a limitation on his perception of society. For him, it brings insight and clarity of thought. It doesn't affect everyone like that.

Maybe you're not implying that, but I hate it when my irresponsible stoner friends (as opposed to the responsible ones who use it correctly) cite Carl Sagan or somebody else to show that they aren't just sitting on the couch unemployed, but expanding their mind.

opiates are considerably more powerful than any marijuana. obviously much more addictive.
 
There is no argument for marijuana prohibition.

Everyone arguing that it should remain illegal, understand that there are millions of highly intelligent people who think you are a goddamn moron. And they are correct.

No recollection of that. I disagree with drug and alcohol use but I consider myself very reasonable and understanding when it comes to people's personal freedoms.


I disagree in many ways; if you get lung cancer and then go on welfare it affects everyone.

But I take issue with misinformation and lazy journalism.

See how we've gone from:
"Occasional and low cumulative marijuana use was not associated with adverse effects on pulmonary function."
to
"Smoking marijuana may not harm lungs"
to
"Marijuana doesn't harm lung function"

Look how quickly we've devolved.



Yes I apologize for lack of specificity of what I was replying to and why.
The comments probably came off as a bit trollish.

And yes, metaphors only go so far.

Hence why I said 'Not if you are Carl Sagan'. Me, like all stoners I know, once I'm high it is a gateway to procrastinating, munchies and sleeping :D

Who gives a shit?

List one legitimate reason to outlaw marijuana.

One.

One.

There are none.

Believing in marijuana prohibition requires a similar level of mental deficiency as believing in a flat Earth.

This is obvious in simple terms of amount of tar ingested per session. Nice to see some longitudinal data.


Absolutely true, smoking anything, any amount, does indeed do harm to your lungs. They are only meant to intake air.

If you don't like the idea of smoking it......you can eat it.

The anti-drug crowd seems bloated with the notion that decriminalizing recreational drug use would spawn some drugged-out loser culture. Stop kidding yourself, everyone over 16 or so who wants to be on drugs already is.

There are people who are comfortable with altering their state of mind, can handle it no bones about it, and understand the ways in which various substances can enhance their lives; then there are other people who are idiots. That's it.

It's quite a bit like the gun debate, actually: pro-drug folk are saying "Drugs don't fuck up lives, stupid people fuck up their lives."

Regardless of your thoughts on marijuana usage, is your argument really "criminalizing an activity doesn't reduce incidence of that activity"? What, pray tell, is the purpose of any laws about anything then?
 
I've been smoking cannabis for 6 years straight... I noticed a big difference between:

a) Smoking straight cannabis out of a bong, vaporizer, bowl.
b) Smoking cannabis out of a joint
c) Smoking cannabis out of a blunt

Blunts are the worst. The tobacco in the blunt-wrap alone is enough to harshly irritate my throat, limit my breathing, and basically slow my athleticism down. And the nicotine "confuses" my high.. I don't really feel good after smoking a fat blunt.

Now that I smoke out of glass exclusively, my whole experience with cannabis has gotten better. Certainly helps that I've been getting some really, really quality tree, lately.

OH, and Connecticut recently passed a Decriminalization Bill for Cannabis!! Gotta love those state's rights..
 
Magic Flight Box makes thick ass coat of resin stick to your throat. You'll see this same coating on the little glass tube that you inhale with. After using it exclusively for a few days it gives you a worse cough than a joint or bong ever would.

It's a cheap piece of crap vape and you get what you pay for.

And this, people, is the very reason why you'll never manage to make it legal.
 
I am all for more studies into the effects of marijuana on the human body. It should be legal while prescription drugs, or the easy availability of them, is something that needs to be focused on and reigned in.....we all know that Big Pharma won't let that happen though.

I can't say you're not right but it never changed my cough nor did I feel anything back there
 
What a worthless study. I don't think anyone didn't know this.

However it will be littered with people convincing themselves they're not addicted to the product due to it not having physical addiction characteristics. I'm pretty sure if I talked about alcohol as much as r/trees talks about pot I'd be a certified AA allstar.
 
Anyone explain to me again why we can't have back our Marijuana Thread? Why not name it "MEDICINAL marijuana thread"? Can't be illegal to talk about prescribed medicine.
