Marijuana Smoke May Cause Lung Cancer

Take Clinton's Advice: Don't Inhale – Pot Causes Cancer

There is a long held belief, by many a stoner, that smoking marijuana poses no health threats, just possible legal troubles. Well, I hate to "bum anyone's high" but new studies indicate that regularly smoking pot poses an increased risk for cancer. It seems that smoking a doobie is bad for your lungs.

Researchers in New Zealand found that smoking one joint is the equivalent of smoking 20 cigarettes because joints have no filter. Plus, pot smokers tend to hold the smoke in the lungs increasing their exposure time to the smoke. Cannabis smoke not only contains twice the amount of carcinogens as tobacco smoke, but pot smokers end up with five times more carbon monoxide in their blood stream when compared to tobacco smokers.

To see how much weed makes for the danger zone, just

It should be noted that the pot smokers involved in the study smoked one joint a day for ten years, or two joints a day for five years (the accelerated approach), and were considered the "high exposure group" – no pun intended. The daily smokers lung cancer risk rose by 5.7 times.

I was a little amused to read that the researchers found it "intriguing" that more research hasn't been done on the cannabis lung cancer connection. Since pot is an illegal drug, I am sure funding for the research would be difficult to come by.

To borrow a line from Nancy Regan, "Just say no to drugs." It is better for your brain and your lungs.

Apart from all the pot and tobacco discussion here I need to mention something very important. Lung cancer is the deadliest form of cancer in US that counts for more victims that other forms of cancer combined together. Smoking is not the only cause of lung cancer, we also have an invisible threat and that's asbestos, so now here we have another serious reason to have an x ray of our lungs, to quit smoking and to have our houses checked for asbestos.

Actually there was a recent study that finds there is NO cancer-marijuana connection.

I've never smoked pot because I've never been interested. If it were legalized, I'd try it and hope I didn't get addicted. I wouldn't be able to satisfy the curiosity until I did. That being said, if I had children, I wouldn't want them smoking pot. If I don't want someone that I love and feel the need to protect to do something, then it doesn't make much sense for me to do it.

I also did some research last night and found that our government spends over 3.67 billion dollars a year on the war against drugs, with such programs as DARE, or other teen and young adult programs. As election 08 is just around the corner, it would be interesting to hear from politicians on why so much money is being force fed into a program that seems to have failed the majority of our generation (people ages 18 to 30). Instead of wasting money on stupid ass commercials where a dog tells his owner that he doesn't like her smoking pot, maybe teach parents how to talk to their damn kids. Also, over a billion dollars is spent each year on jailing offenders, court fees, etc.
There are ways around smoking it. Of course smoking a piece of paper isn't healthy, and there are carcinogens in burning paper. But, you can make butter and cook with it, and thereby totally bypass the lungs. You can also buy vaporizers which set at the exact correct temp as to get the vapor from the THC rather than the smoke. Either way, if you wanna make everything that causes cancer illegal, you better stop drinking the milk in your fridge, the water from your faucet, tanning (duh!), walking down the street in a city, inhaling the fumes from the back of your car or your neighbor's ungodly SUV. Stop talking on your damn cell phone, don't microwave anything, don't set food on your granite countertops, stop dying your hair that perfect shade, stop drinking all that alcohol on Friday nights, and drop the diet soda.

Yeah, i knew someone would bring up the "topically" etc...i dont know about internally...unless its an open wound or something and they use rubbing alcohol or something. Thats not what i was talking about. Its not like they open some Jack Daniels and say "Here, drink will help your tummy ache" or something like

alcohol is used extensively in medicine. both topically and internally. frequently just as a solvent for delivering some other drug.

The best way to avoid inhaling any cancerous toxins is to buy a vaporizer. They can be pricey, but some personal ones are only about 100 bucks. They elliminate the harsh toxins and that you only inhale pure THC. Its wonderful. :D

Wow...i love what a lot of the people have said on here. I could quote so many....atleast those who are arguing FOR legalization of marijuana. Arrgh...i could go on and on about how alcohol is so much worse. You dont ever hear of them using "medical alcohol"???? um...yeah, didnt think so. Yet, i am sure most all of you who are against marijuana drink on a regular basis. Just the fact that they have approved marijuana for medical purposes is one step in the direction of making it legal. That "gateway drug" argument is nonsense. I have smoked marijuana for several years now...have stopped for months at a addiction...just pure enjoyment. Never EVER have i done any other drugs..nor have i wanted to. I've certainly been around them enough..but no desire to graduate from my beloved MJ to something stupid like heroin or cocaine. I just have a love of the pure relaxation that smoking a little herb can bring. :D

It's interesting to note that there are cannabis receivers in the brain; their sole purpose being to react with THC. So it's more of the method of receiving THC than the drug itself that poses a threat. At this point, I think people realize that if at any point in your life you're inhaling smoke into your lungs, it's probably not going to be good for you. On a side note, I feel that people choose to be lazy potheads. Some are fully functional, healthy and have really good jobs :)

No one I know that smokes pot smokes that much! Most usually do on weekends. Who smokes 2 joints a day?!? Besides usually no one smokes a whole joint by themselves.

I am against drugs and have never done any; however pot has helped reduce some of the negative effects from cancer treatment so the patients could at least perform everyday activities until the high effect wore off (being happy, munchies, etc..) So I think if allowed for cancer patients for just a brief time during their treatment it would be okay, since it wouldn't be a year of smoking, it would only be a month. If it helps them out, I agree with it.

Water pipes eliminate much of the carcinogens, they are left in the water. Also, vaporizers are an expensive option which remove even more. Most importantly, no need to hold the smoke in. If you are doing all of that, the marijuana is no good. It should be one or two hits and done. But I'm not a smoker. Also, what keiren63 wrote. I'm giving you a virtual high-five, well written!

Renees - I hear what you're saying but I see it from a different perspective. People who would be open to doing other drugs start with pot, sure. But, not everybody is even a possible candidate for a heroin addiction. I have smoked a lot of pot in my lifetime (disclaimer: haven't in quite a few years) and have been offered many other drugs that I'm sure have equally if not more fun highs, but I'm aware of the problems they can cause and I'm not interested. Look, I don't need the government to tell me what I should or shouldn't do to lead a healthy, productive life. And people who do need that aren't likely to listen to it. And, for the record, people have caused accidents stone cold sober talking on cell phones, eating burritos, fiddling with their radios, etc... And people have almost burned down their houses stone cold sober forgetting to turn off their stove or leaving candles lit, etc... Not everything that is unhealthy or even potentially dangerous should necessarily be illegal. So, given the problems that the war on drugs does cause, i.e. enriching gangs and drug dealers, encouraging violence and driving the entire thing underground where there is little to no accountability not to mention filling our jails with nonviolent offenders, I haven't heard a good enough argument as to why we should continue that.

Look, the media shows what a certain group wants to show people. This started back in the 1800's, look up The Sacking of Lawrence online. Just as then, the media persuaded people by putting their beliefs in the media. You can google does marijuana cause lung cancer? and there are all these researches that say marijuana does and some the say marijuana doesnt. It boils down to this, Marijuana is not a gateway drug. I have been a smoker for a year, and have never even thought about using any other drug. Also, anyone who says marijuana is addictive is a liar. I am in college, have a 3.0 gpa, a job, and smoke almost every day, but am able to not smoke for weeks, months, years, and would be fine. My point is, everyone needs to just drop all of this judgement stuff and just respect the lifestyle a person wants to live. Nothing is more annoying then listening to all of my friends who drink alcohol say to me, damn, your always using drugs. Isn't alcohol a drug? Just be yourself do what you wanna do and let other people live the way they want to. Also, the legalization of marijuana is an issue that should be brought up in our government. Im not saying it is more important than major issues such as immigration or poverty, but with our economy looking like it may go into a recession, new ways of funding certain things need to be found. And for all of the people who want to talk about how bad marijuana is think about this. Alcohol- 100,000 deaths per year legal Tobacco- 400,000 deaths per year legal Marijuana- No causes of death found ever illegal

Another reason that pot was illegalised was becuase, in WWII, the DuPont company invented Nylon, which was used to make rope on Battleships. It was a strong fiber, however, nowhere near as strong as Hemp, which was used up until then. So to fill their greedy pockets, they made a deal with the government to spread anti-marijuana propaganda and to make growing hemp illegal. Another reason that benefits the government is so that police can control gang warfare - give us a cut of the drug money, we won't arrest your crew of 14 year olds gangbangers and instead arrest the drug dealers of the rival gang. It all boils down to money. Especially with something as harmless as pot. I can't fully say that Pot is good for you.. I can't imagine that it is. But it does not ruin lives in the manner of other drugs.. including ALCOHOL. Pot doesn't make you angry and willing to fight others. Pot doesn't make you black out and forget what you did the night before. There has never been an instance of Lung or Liver Cancer connected to smoking pot. I think it boils down to being a lifestyle choice and as long as the people in your life aren't suffering because of it - in the way that alcoholism ruins families - then it is ones civil right to make the choie for themselves.

The only reason that marijuana was ever made illegal in the first place was because the government saw that Mexican immigrants were bringing it in and smoking it. This is where that whole "lazy Mexican" stereotype came from. Pot wasn't banned because of its health was banned because the people running our country back in the day were racist. I smoked pot for 6+ years and have now been clean for almost a year. I'm not saying I will never smoke again and I'm not saying people shouldn't smoke I just got to a time in my life when I needed to stop for personal reasons. Pot IS NOT a gateway drug, but it CAN BE. Just like alcohol is not a deadly substance, but it CAN BE. If you abuse anything you are going to be in trouble. But I honestly have never believed that smoking pot is worse for you than smoking cigarettes. I think it's just coming out with that statement so that all the people against pot will be like "see look what they have proven now" which is dumb. All the people who don't smoke and don't agree with pot should just keep their opinions to themselves. Stop preaching. Pot smokers do not preach to non-smokers about how they should smoke or how they should stop drinking at the bar every single night. So non-smokers should stop preaching to people that think pot is OK and realize that people will do what they want.

I keep coming up with all of these rebuttals to the gateway drug argument. 100% of criminals have tried wheat! wheat must be the cause of their crimes! anything is a gateway drug if a person has an addictive personality. alcohol, pot, whippets, that game kids play when they make themselves pass out... pot is more like alcohol. not a good idea at all in excess, but it does have it's moments. it's up to the person not to abuse themselves. having a glass of wine doesn't make me an alcoholic, having a bottle every night to get myself to sleep does. "that pot made me do crack." f that, that pot made me sit on the couch and eat fritos. you choose to move on to other drugs. I've never been even tempted to try other drugs, despite all of that gateway crap. oh, and my favorite stoner joke: what's the difference between a drunk driver and a stoned driver? a drunk driver will blow through the stop sign, the stoned driver will stop and wait for it to turn green.

jennifer, I understand that of course people have done other things before doing drugs. But as I said before, I've been there. Most of my friends are recovering addicts as well. I'm not jsut making this up. Personally, I smoked weed before I ever drank. I think I smoked a cigarette around the same time. That's not my point. The point is that when I smoked weed I liked it. Then I realized there were other things out there that would give me more satisfaction than weed. It's a progressive disease. That is a Known fact. Tolerance, addictive personality, availability, crowd. All of these things contribute to it, but it IS progressive. The reason I bring these up is because when I hear people debating this, the pro legalize it side always brings up how it doesn't hurt anyone and I beg to differ. I know people that have cause accidents, or have almost burnt down their home being stoned. I don't think it's should be banned simply because it's bad for you. I just haven't heard a good enough argument as to why we should legalize it that would counteract the bad.

Well, I'm sure that hot, tar-laden smoke is not good for your lungs. Anybody that's gotten a good look at resin should know exactly what's going in to their lungs. But, I've read about the same study as keiren and find it credible as well. And, I'm definitely not in the "if something is bad for you, it should be illegal" camp. The legalization debate can go on ad infinitum, but I just can't let the whole gateway thing go by without comment. Yes, you'll find that most people who do hard drugs, did pot first. You'll also find they smoked cigarettes first. You'll also find they drank alcohol first. You'll also find they went to school first. You'll also find they ate peanut butter first. Blabbity blabbity. Nonsense argument.

yes eventually you will die from something. And yes it can be argues that cigarettes and alcohol are just as bad HOWEVER, Lets say that cigarettes were illegal, and we knew everything about how hazardous they are do you think people would be wanting to legalize them? Just because there are other bad things out there that happen to be legal because of the way cultures developed before we knew the consequences doesn't mean that we should legalize other things that are equally if not more harmful. and lets be honest because Pot isn't legal it is really hard to have studies, and such about its effects now isn't it? and "THC actually protects the lungs from most carcinogens." really that sounds as dumb as people who say smoking helps to dissolve cholesterol. THC is not exactly a substance you want to be putting into your body. and seriously I don't think the govt won't legalize it because they enjoy arresting people for it... My father was a substance abuse counselor, and most of the people he treated ended up with addictions that started with a little pot smoking. basically what I'm saying is yes there may be some bad things out there already, and any number of things can kill you/ give you cancer, but that doesn't mean we should add more to the list.
