Smoking One Joint Of Cannabis Has Same Effect As Five Cigarettes

Smoking a single joint of cannabis has the same impact on breathing capacity as up to five cigarettes, according to a New Zealand study published on Monday in a specialist British journal, Thorax.

Medical Research Institute of New Zealand doctors recruited 339 volunteers, who were divided into four categories - those who smoked only cannabis, those who smoked only tobacco, those who smoked both, and those who smoked neither.

Cannabis-only smokers were defined as those who had smoked the equivalent of at least one joint a day for five years; tobacco-only smokers were those who had smoked the equivalent of a packet of cigarettes a day for at least a year.

All the participants were scanned by computed tomography (CT) to get a high-definition image of their lungs and were given tests to assess their airflow, the term for their respiratory efficiency.

The most serious damage was found in tobacco smokers - both tobacco-only and combined users - who were the only volunteers to have emphysema, a degenerative and crippling lung disease.

Cannabis smokers had lighter symptoms, such as wheeze, cough, chest tightness and phlegm, which tobacco smokers also had.

But the CT scan also revealed that, among cannabis smokers, fine damage had occurred to their lungs. This had happened in small fine airways that are important for bringing in oxygen and taking away waste gases. As a result, their lungs had to work harder.

The extent of the damage rose in proportion to the number of joints that had been smoked. In statistical terms, each joint that was smoked was the equivalent of smoking between two and a half and five cigarettes in one go for impairing lung efficiency.

The researchers, led by Richard Beasley, said the discovery of this hazard is "of major public health significance" given that cannabis is the most widely-used illegal drug worldwide. According to the 2006 report by the United Nations Office on Drugs and Crime, an estimated 160 million people use cannabis.

Beasley suggests that the reason for cannabis's heavy toll on the lungs stems the fact that joints are usually smoked without a filter and are smoked down as far as possible, which means the smoke is hotter when it arrives in the lungs. In addition, cannabis users tend to inhale smoke more deeply and then hold their breath in order to get a bigger "high".

On Saturday, a study published in the British journal The Lancet said there was now clear evidence of a link between cannabis smoking and mental ill-health.

It is common sense that smoking ANYTHING will damage your lungs in some way. This is not a properly prepared article or valid evidence that cannabis is bad for you. Most people who choose cannabis as medicine use it through a vaporizer, water filtration or paper filters (if a joint is smoked). Please educate yourself fully on the topic before writing an uneducated, bias article that give the impression you don't research your work.

Cannabis prohibition is racist in origin.

Sorry, but "Smoking One Joint Of Cannabis Has Same Effect As Five Cigarettes" is bullshit. There has even been research that suggests that its much better for you. Apparently cannabis causes damaged cells to die, whereas tobacco causes damaged cells to stay alive and turn into cancer. Thats the basic jist of it, but I could be wrong.

However, these scare tactics are definetly not backed up by facts. Its today's equivelant of the anti-cannabis lies and propaganda used in the 1930's. Do you know why cannabis was made illegal? Because in the 30's newspapers had articles claiming that "marijuana causes negros to look at white women" etc. Seriously. No facts, no scientific research. It was outlawed on racist lies.

I smoke through a water-pipe as much as possible. I also add ice when it will not effect the operation of the filter water. I also have a perk-pipe that has two water-chambers. I also use a vaporizer and eat baked goods. I use cannabis that is not bricky schwag. I smoke high-end THC-filled chronic buds, everyday. With that said, I can feel the damage done to my lungs when I smoke joints, blunts, bowls, pinchies, etc. My personal (unscientific) conclusion is that is not the cannabis, but the actual smoke and it's temperature that causes the problems. Also, true smokers know that holding a hit only damages the lungs, not get you a bigger high. THC takes something like 1/100 of a second to enter your blood stream. Holding the hit makes you lose oxygen and damages cells making it FEEL like you are getting higher... but you are really getting deader quicker.

It is really intresting with everyones views, but im a pothead and i know estimatly 130 potheads and nearly each of them smoke up to 15 spliffs a day. Ive smoked it since i was ten and, im now 17 and im in perfect condision, docter says my lungs are perfect and im in great shape.

Many of my mates smoke the same amount and have been smoking with me for the last 5 years and they all keep up with me in every psycal sport going gym, footy ,rugby, base ball, cross country, high jump and so on my point is skunky... actualy even resin has different effects.On different people with different life styles and how clean they smoke the stuff cause there is lots of added things in most stuff nowdays. in fact you can get most lung dieses or anything people have said you get from smoking from just breathing air nowdays.

All i can say is pratice breathing patterns and do running and stuff keep yourself and your lungs fit it will help with other things ofcourse to just follow the path you choose

alright id like it first to be known that i am high right now, i LOVE pot, i even share it with friends ;), but ya ive read over this artical a few times... (blame the pot for that one)now this comming from someone who smakes 1 daily joint, i do find that smoking pot and smoking cigs has a much different impact on your body... if i smoke 1 cig before bed, i wont wake up with total party lung... but if i smoke a joint then hit the hay, my lungs kill me the next day... but i dont think its as extreme as smoking 3 or 5 ciggerets in 1... there for i conclude that this artical needs to be redone with credable evidence done on perticipants who only smoke the average joint. which im guess is 3-5 a week.

i dnt think smoking just 1 joint of cannabis has the same effecvt as 5 cigs. i think the person which wrote the article needs to look at everyones comments and then make a few changes.
im 29 yrs of age have been a cross-country runner for nearly five years now. smoking dnt hold em back. ive been smoking joints since i was 17. i cant actually say i feel fine coz i would probably be healthier if i didnt smoke it but all i can say is that everything in my body works properly and i have no serious damages to any body part. i feel great and it dnt seem like im ageing which is a fab for a woman. i enjoy life and i dnt drink or take nothing else, so its not like im have a problem or something. i believe there is nothing wrong with smoking cannabis and i wanna bless all those other potheads out there. god bless everyone xx sexy biatch nady xx

I'm surprised I'm the first to mention this point... but since when did it become the government's role to make illegal everything that is bad for you? If that's the case, they've got a lot more prohibitions to work on... they should forbid us from drinking alcohol of course, and eating fast food, and even going in the sun because that gives us skin cancer. It's definetly a slippery slope when the government starts telling us what we can and can not do based on what is "good" or bad for us. Come on, are we really too dumb to make our own decisions or does the government really need to micromanage us?

I guess this is a good place for my second point. Doesn't the government realize that if they would just legalize it, they could be making so much money? They would save billions of dollars from adminstrative costs, feeding and sheltering those who have been imprisoned on marijuana possession and distribution charges. Courts would clear up from fewer charges. Law enforcement officers could spend their time on more important problems. Drug-related problems, such as gangs and the black market, would be drastically reduced as well. Furthermore, the government could actually use this to earn money by imposing taxes! What the heck is their problem... do they not see this?

well i was reading the ewspapers a few weeks ago, there is scientific fact that there are chemicals in marijuana actually help cure syndromes and diseases such as Alzheimers, and arthiritus. These have been, until now, pretty much uncurable, leaving all these unfortunate people in ill health, because some scared scientists were afraid that cannabis was bad. You lot who think its bad can suck my balls, its as good for you as chocolate, or porridge, or some other grown in the ground foods.

Hey all readers!
Firstly i am a cannabis smoker myself!

I have educated myself to the limit on the topic 'Cannabis', i have researched all aspects of Cannabis such as Law, Recreational, History, Effects and other areas.
As a media student i made a documentary about Cannabis, i interviewed drug councilors, researched the drug to the maximum i could.
after research i found that Cannabis much better for you than any other illegal drug out there also better than alcohol.
Some 'uneducated' people say cannabis can lead to schitzophrenia (if that's correct spelling), who's to say that it wasn't already there. Same with cancer, everyone has cancer genes, it just takes anything but something to 'kick it off'. No Cancer is due to Cannabis, cancer is caused by tobacco.
If Alcohol was found in this day of age, it would illegal because of the damage to the body and mind.
I smoke several joints in a single day, i have been for years now and there's no bad outcome from this.
I agree that smoking joints is worse for me than water pipes/bongs, vapourisers etc.. due to the tobacco, but i find this way is the easiest and most recreational. It's how i started out smoking cannabis.
For the best weed in the world, i advice going to Amsterdam, the weed is so much cleaner than over in the U.K. also the black has no crap in it. I refuse to smoke black in the U.K, simply for the reason that only a small percentage is actually cannabis the other percentage is crap such as vinyl, plastic, oil, petrol and other harmful poisonous materials.
Cannabis is also used as a medicianal purpose, there are so many illnesses and diseases that cannabis helps to not cure but help. Cannabis is mainly and most commonly used as a natural source of pain relief.

I can't think of any more to write apart from the conclusion which is Cannabis is no harm.

personally i think Cannabis has opened the world to my eyes, i see more than others, i enjoy the countryside more and nature, and weed as a plant.
Cannabis makes life so much better, so much stress free lifestyle.
I don't see the point in stress, it only causes illness.

Life is short, why waste it, living amongst the society we have todays. the government is currupt. The media has it's hands on all the world!

Get out there, do what you want. You only live once. Only never go out with the intention on hurting others!

The only reason why the world is making such a propaganda on marijuana as a DRUG is because the government couldn't get any TAX from it!
If the government could get money from people growing and buying marijuana, then only it will be legal.

Chantix, the Pfizer manufactured quit smoking medicine is to be definitely opted for if you are eager to get rid of smoking addiction and if you administer Chantix in accordance with the instructions of the doctor, the medication would certainly relieve you from the shackles of nicotine addiction. However, if you don`t follow the chantix precautionary measures while taking the medicine, it is capable of causing tremendous harm to your health.

I have smoked cannabis for more than 20 years, have no signs of any kind of illness and actually I am far more loving, sensitive and creative than before I started. This is another shitty attack from the lobbies who wants this miracolous plant to be suppressed. Look at the facts how many people destroy their lifes with alcohol instead, real cause of social disorder, violence and death. No one has EVER died from cannabis you morons. Stop perpretrating such barbaric proibitionism which leads millions to jail for the simple choice of using a PLANT rather than man made drugs. LEGALIZE CANNABIS!! CANNABIS = FOOD, FIBER, PAPER, OIL, PLASTIC and MEDICINES, ALL PERFECTLY SUSTAINABLE!(and with the bonus to make you nicely high without horrible hungovers next day!)
