"Don't smoke! You'll get cancer!" They say with a large cheeseburger in one hand, while digesting 3 energy drinks.
Never underestimate the power of addiction.
Yet people continue to smoke...

If smoking kills, then why won't the government ban cigarettes? Answer: they doesn't give a single f*uk about it's citizens, only money > profit.
Smoking Marijuana is bad as well, inhaling smoke of any sort is stupid.
I think doing sports is the best way to quit. I remember I never smoked just before running, I couldn't smoke meanwhile and my lungs were killing me afterwards. That were like 1 - 1.5 hours I did not think about smoking per day without any issue. It doesn't sound much but if you start with a couple smoke free hours a day you can slowly extend it. At some point I managed not to smoke the entire time at work. That was a real mile stone! I kind of made it a challenge and tried to break my own records. After a while smoking actually got annoying all by itself because I started to smell how it stinks because my nose was kind of "clean" when I got home. It's like when you smell your older clothes after you have taken a shower. You better put on fresh ones. I was also curious how my stamina would change so I just went for it at 8 o'clock in the evening on september 9th 2009. Now 2015 I never think about cigaretes anymore and I don't remember the last time I did. The memory is completely gone and smelling smoke of others is just disgusting. You just have to be careful, don't become that former-smoker asshole who wants to cure every smoker he meets, posts stuff on the internet and what not. :)

Is it just me or did the editor not filter out background noise/static?
well i am somking wihle watching this video
I just don't understand how can people be addicted to smoking (yeah I know it's nicotine). My smoking friends often offered me some cigarettes, I find there's nothing enjoyable about inhaling poisonous smoke that irritates your airways. Plus it makes your breath stink. If you want to smoke go ahead but don't do it near people who don't.

I've been watching cigarette vs health related videos to make me feel better about quitting, and this one takes the cake. It sucks to not smoke, I get into my car and I want a cigarette. I've got some time before that addiction goes away. Anyway, my will power is strong, addiction is just in my head.
John Davidson
I have stopped 7days ago
Trey Stephens
So what you're saying is that I should smoke for my health?
Basically if its not 100% natural don't do it. Before anyone becomes a wise ass, nicotine isn't 100% natural because of all the chemicals that are in it.
For me, the most off putting habit a person can have is smoking

I want to see more studies on smoking pipe tobacco. Pretty much everything I ever see about the risks of smoking is aimed at cigarette smokers. I have never smoked a cigarette in my life, but I began smoking a pipe about a year ago. I know that in general pipe tobaccos have fewer additives. Also, most pipe-only smokers do not inhale. I've known several pipe smokers in my life, many of them family members... and I'd say that on average all of them have lived well into their 80's and 90's, and only one of them had cancer. My grandfather was a pipe smoker and he had heart disease, but he was almost 100 when he passed away, and the cause of his heart disease was linked to other factors. I found a couple of studies that suggested that pipe tobacco is up to 16 times less harmful than cigarettes depending on how much you smoke, but they are questionable sources. Again, some of those questionable sources have stated that pipe smokers tend to have lower blood pressure than cigarette smokers... Long story short, I want more credible research on the effects of long-term pipe smoking, because I believe that there are differences, but to my knowledge, no credible academic research has been published.

Id rather live a short life smoking and drinking partying and having fun with friends getting 1000x more dopamine in my lifetime than a healthy boring lame long life person.

Listen guys... TOBACCO: -There are over 4,000 chemicals in "tobacco" smoke and at least 69 of those chemicals are known to cause cancer, WEED: -There are over 480 natural components found within the Cannabis sativa plant, of which 66 have been classified as "cannabinoids;" chemicals unique to the plant. The most well known and researched of these, delta-9-tetrahydrocannabinol (Δ9-THC), is the substance primarily responsible for the psychoactive effects of cannabis. --- Deaths : Tobacco : 400,000+ alone in 2001, 120,000+ in 2005 alone, WEED : 0/ until 2015 October 27, -- Cancer: Tobacco : it causes, Weed : Cures (thanks to Delta 9 THC) -- Addictive: Tobacco : Highly, WEED: it doesnt have addictive components (if u score it daily for more then a year u might create dependence) -- SUMMING UP : SMOKE WEED EVERYDAY... :D --- A number of small studies of smoked marijuana found that it can be helpful in treating nausea and vomiting from cancer chemotherapy.A few studies have found that inhaled (smoked or vaporized) marijuana can be helpful treatment of neuropathic pain(pain caused by damaged nerves).Smoked marijuana has also helped improve food intake in HIV patients in studies.There are no studies in people of the effects of marijuana oil or hemp oil.Studies have long shown that people who took marijuana extracts in clinical trials tended to need less pain medicine. More recently, scientists reported that THC and other cannabinoids such as CBD slow growth and/or cause death in certain types of cancer cells growing in laboratory dishes. Some animal studies also suggest certain cannabinoids may slow growth and reduce spread of some forms of cancer.

I quit smoking a month ago but after listening to your annoying voice and judgmental attitude...I'm going to buy a pack now!
Jack Pat
people will still smoke. Even if they watch this video. no matter how many videos we can publish against smoking, nothing will stop them except charging millions for cigarettes and offering free quit smoking sessions. That's the only way I see it.
With all this evidence and still smoke? Well most ppl who smoke are ignorant that's why. Same goes for people who eat animal products.

I don't even get why smoking isn't banned yet
From what I read the most positive effect of smoking is it lowers stress. You know what also lowers stress but costs only $5 to $10 and wont lead to lung cancer, Beta Blockers.

Arsenic, Beryllium, Cadmium, Copper, Lead and Mercury are all elements that cannot be manufactured in the tobacco plant or created by burning the tobacco plant. All of these elements, except copper, do not contribute to the plants growth or functioning. The only way these elements can get into the tobacco plant is by uptake from contaminated soil or water though the roots, which means that the farmers growing this tobacco are being extremely negligent or someone is putting this stuff in tobacco to deliberately hurt people. If your food is being grown in the same region as this tobacco, you may want to check out its chemical analysis as well. Then you will probably not want to eat those fruits and vegetables anymore because they will also be carcinogenic.

Knowledge of the damaging effects of tobacco went back, but further than this century. Its effects on ones lungs were noted in King James I's " A Counterblaste to Tobacco", and Francis Bacon observed its addictiveness.

yeah im actually about to go over and grab a pack :)
When u smoke u dont just damage yourself you damage others too, plus why did humanity create smoke anyway?
So, for the question of why people smoke, I started because I wanted to die at the time, then I quit for 3 months to better my health(I intended to quit completely), but then I picked it up again, and I quit again because I figure it'd bad to get lung cancer and die. It is so hard to quit though, if it weren't for regular chewing gum and a shitty e-cig I got I'd probably have punched someone in the face, especially with the stress of school(I'm in college, it's my 3rd year, and I am studying computer science, so some pretty technical shit). And if you are thinking about smoking y'all better just do something else that is a bad habit, like chewing obnoxious amounts of gum.
Amanda Byrd
I wish my mom would stop.
Ik this is completely out of topic but I truly believe I was addicted to hot Cheetos. I would eat them every single day, one time I was craving it so bad I made my mom go to the corner store with me at like 11:30 pm to buy a dollar bag of hot Cheetos. the consequences of me eating this everyday resulted in bad acne and a painful poop everyday morning. I kept telling myself I won't eat them no more but I kept reaching into the bag eating more and more. It was really hard to stop but once I did only for the benefits of my skin- I never even thought of eating those again. And sometime last month I almost got back on the same train but after eating them for three days straight I broke out with a huge pimple so I stopped immediately. Never again, maybe once in a while .
This was nothing new. I'm aware of the risks and have known for YEARS. Slow suicide. . . works for me! ~takes slow drag~

Step Back History
There is a bit of a dark side to the success of the anti-smoking campaigns in the west. A lot of those cigarette companies moved out to exploit the lack laws in countries like china and Indonesia. Also, the way we did the campaign meant that we blamed the smoker rather than the drug, leading to poor support for quitting and really low amounts of research money for lung cancer research. If you know a smoker, give them the love and support they need to quit and stop harassing them.

Why can't government make illegal to produce all those harmful stuff. I've tried to smoke, drink but never got addicted. I just don't know why people use those slow poison. Now i don't smoke, drink I'm done with those stuff.

I often hear people justify smoking by saying, "We're all going to die anyway." Well, if you're lucky, you'll die quickly from a massive stroke or heart attack. But, most smoking-related issues will actually kill you very slowly, potentially over decades. And, during that whole time, you suffer more than you thought was possible. And, all your friends, family, and anyone who cares about you can do absolutely nothing but watch. My dad (77) and my father-in-law (55) both smoked for many years. And, both have nearly lost their lives because of it. My dad was first diagnosed with heart problems almost 20 years ago. Despite that, he continued to smoke. Ten years ago, he had an aortic aneurysm. That very nearly killed him. The doctors told him he had a less than 20% chance of survival. But, he did survive. The doctors told him absolutely no more smoking. That only lasted about a month before he started again. Earlier this year, he was diagnosed with emphysema/COPD and heart disease. But, even then, he still wouldn't quit. But, this summer, he finally quit. Being in a medically-induced coma due to life-threatening pneumonia for 2 weeks followed by 4 months of hospitalization forced him to finally kick the habit. At one point, things got so bad, my mom had to sign a DNR form. He only recently came home from the hospital about 2-3 weeks ago. But, it's not over. He'll need home health care and oxygen treatments for the rest of his life. Fortunately, my father-in-law hasn't suffered quite as much damage to his lungs as my dad did. He also has COPD, but it's not as advanced or severe. Instead, smoking mostly damaged his cardiovascular system. He's suffered multiple strokes, and doctors are afraid he could have another big one at any time. The strokes have left him with muscle twitches and permanent speech problems, and he can't walk without without a walker or a cane. Before the strokes, he was a very active person who absolutely loved building things and working with his hands. Now, he can't do any of that anymore. Being forced to give up the activities you love for the rest of your life can be a major psychological hit and cause serious depression. Having seen first-hand what smoking does to a person, there is absolutely no way I can condone it. If you smoke, I urge you to quit. If not for yourself, then at least for your family and friends. But, if you're absolutely hell-bent on killing yourself, I suggest you find a faster and more effective method.
If yo smoke now it’s had to quit now but after a few decades of smoking when you get sick the suffering will be 100 times greater now !, yes I have seen it happen to men who I have loved . O yes your medical bills will be astronomical and you will not be able to pay . So you goon the public nickel . Well many all the taxes you pay on a pack will help . Only a dam fool smokes that’s the bottom line
I am Literally Tearing Because my dad Smokes 😭 GUYS PLEASE TELL ME HOW CAN I STOP HIM 😭😭😭😭😭😭🔫
My experience with smoking is I think an unusual one. I first tried cigs at 16 along with weed, tried cigs after weed more due to curiosity. Tasted like shit, shit buzz, but it did have the redeeming qualities of relieving stress and reducing nausea which of course weed also does and does better. I still smoked cigs occasionally though, more socially than because I felt the _need_ to. This continued basically for 10 years(26 now) where I would nearly always have a pack in my room but almost never smoking them. Most of the time a single pack would last anywhere from 2-6 months, and the most I would ever smoke is 2 cigs in one day 3 at the most but most days I didn't smoke at all. To update on how that has gone more recently, I think it has been probably close to a year since my last cig, I got my medical marijuana card a couple months ago for my back, I gave away my last pack of cigs since I had no desire for them. Now that I have weed I'll probably never smoke cigs again, oh and I don't actually smoke it either I vape pretty much 99% of the time so even less health risks than you would normally have from smoking.
Smitty Johnson
I don't smoke. That being said, I find it funny that people get self righteous about not smoking when they knowingly eat food that will shave decades off their life and avoid food that could add decades to their life. As long as you don't smoke around people who are forced to be around the smoke, (like smoking with your kids in the car), it's no worse then people who have bad diets. Cardiovascular issues like heart attacks and strokes kill far more people in the West then smoking and those illness are just as preventable for a vast majority of the people who suffer from them as the health issues caused by those who smoke. In other words, it's awesome that the dangers of smoking have become mainstream but the smoke shaming is hypocritical. It's your body and you have the right to do with it what you want.

But Keith Richards doh...
Patrick McAsey
Without question most smokers want to give up, some desperately. Unfortunately, so many try to give up again and again. Smoking is really pernicious: it's a very expensive, very painful way to die, often young.
Gytis Janusevicius
I know smoking is bad, but think about it like this : How many people do you personally know that died from smoking? How many of your friends, family or even relatives personally know a person who died from smoking? The answer is probably really low or even 0 So I doubt it's THAT bad, maybe 2 packs a day is not okay, but 2 to 3 cigarettes will not kill you

Cirareetes cost about 3 cents to make a pack and wholesale for avout 1o cents a pack with the Grocery Store averaging only about 40 cents profit...all that extra you pay is State and Federal "Sin tax" And , using Hawaii as an example of political hypocriticism, the State of Hawaii got a Billion from that "Big Tobacco" setelment that was eventually overturned out of the media's eye...but put most of it into the general fund and used none of it to cover medical costs of dealing with dead smokers (smokers die sooner so that they;ll live long and stress government healthcare is bs) and the "sin tax " in Hawaii averages about 3 million dollars a month yet they only allocated about $50,000 of that over 10 years to promote kids not to smoke and to help adult smokers to quit There was a big Anti-smoker hooray with they banned smoking in public places and in bars and made it illegal to stand 50 feet from a door when smoking and the "Sin tax" dropped to only 200,000 a month instead of 3 million a month as people smoked less or quir and there was a total freak out leading to the laxing of the outright smoking ban (out of the public/media eye) which once again increased the amount of "sin tax" filling the State Coffers Gotta love politics....and dont even get me started on fossil fuel tax income of the states and feds and why the Federal Government or State governments would never ban fossil fuels (aka slay their golden goose)

From what i understand before watching this video, smoke of any kind makes your blood react as if you had a gushing wound thus causing heard disease. Its said in this video yep... But weed has been found to have health benefits, and what about non-nicotine products? Like researching and buying tea leaves so you know exactly whats in it, and then smoking the tea? And what if you dont do it regularly and give your body time to heal? Would that reduce the negative side effects? And how about vaping? 4 minutes cant explain everything, can it?
Tony DoMonte
smoking still kills so many because of the "tobacco master settlement agreement". it means big tobacco gives each state money and its directly related to how much tobacco is purchased in that state. the states spend the money years in advance before the money even sees the light of day. now the states are starting to panic so they are pushing a ban on vaping products such as electronic cigarettes. ignoring that every study suggests that ecigs are 95% safer then tobacco. the whole European Union agrees. the states and big tobacco both are funding the " truth about vaping " ad's everyone is seeing all over the place. they dont want you to quit. they dont care about you. they want you to keep smoking so they can pad pockets and keep the crap going. also, none of this is opinion... its factual information and you can get off ur ass and do some research before you comment.

some smokers are very ignorant of non smokers they puff away and force people who have asthma to move away from them. i've experienced that a lot of times and its even worse when your recovering from a chest infection and your astma is playing up and someone is puffing away. also there a street where i get my bus and office workers take up the whole of the footpath while on their smoke break and ive missed my bus because they are in everybody's way. also people flicking their ash into your bag! i was carrying a bag of food shopping home with me and the bag wouldnt shut it was so full and there was me standing there and some woman who was in her 40s or 50s lit up a cigarette and was flicking the ash into my bag and it was getting over the food. i felt it was really ignorant.
I find it hilarious how many "Already dead" people we have. Smokers of cigarettes all have the same story which makes them failures. 1) started smoking cigarettes to gain some type of acceptance by their peers, basically you tried fitting in with a crowed who doesn't care about you 2) you started experiencing nasty side effects or detoxing once you tried stopping becoming depending of it or, you simply accepted smoking as normal 3) you completely forgot or wouldn't expect that cigarettes is actually a drug, one of the worst kinds but still somehow manage to poke fun or look down on other people for using drugs which gain a negative spot light and are recognized more, not all companies can cover their asses the way a tabaco company can while 4) you all convinced yourselves your better then those with addiction habits it makes you feel more intelligent 5)you tried to stop at some point in your life but failed cause your a dumb fuck 6)you got the diagnosis and started crying still not accepting that it's your fault your dying while leaving everyone to suffer

Are we going to stop driving motor...vehicles because the atuo emissions is 100 times weirs for you to inhale then any amount of cigarette I only pedel a bicycle so why should I be forced to breath in your second hand car emmissions?
Lane King
Wonder if this is also the same with things like pipe tobacco and fine cigars, yes still risk of gum cancer and such however you don't actually inhale so I wonder if you're using a filtered pipe or cigar if this is still correct, after all pipe smoking and cigar smoking are much different than cigarette smoking particularly that the tobacco is treated with zero chemicals if you're buying fine tobaccos such as a $100 Cuban organically grown and hand made with the finest tobacco leaves. Would be very interested to see a study like the one done on cigarettes done on pipes and cigars.
Between the circulatory or cardiovascular disease, high blood pressure, heart attack, stroke, cancer, emphysema and lung damage, smoking will lead to an early death ... `There’s one adverse health effect that nicotine is clearly, unequivocally responsible for, and that’s addiction. There’s a quote that’s been bouncing around the tobacco research community since the 1970s, that “people smoke for nicotine but they die from the tar.” But the addiction, “in and of itself, is a distressing health outcome,” says Adam Leventhal, a clinical psychologist and a professor of preventive medicine at the University of Southern California. People who are addicted to nicotine “can feel that their behavior is restricted by their intense urge and cravings to use the drug,” he says.`
I have been alcohol- free for a year and a half and tobacco- free for over two months, both still counting. I must get likes on this, or else, I am sure to relapse

I was smoking while watching this and still am while I am typing this. The city that I live in smoking is nothing compare to the pollution. I know I know, you gonna say well if there is pollution lower the risk by stop smoking. However, then there are life problems that smoking really helps from the placebo affect that it has. so there is that. Whenever, the world is a better place to live in, I will stop smoking. Thanks this was very educational. Love your work
Great video Julia and DNews! I'm constantly surprised people continue to voluntarily damage their circulatory and respiratory systems puff by puff. I use to be a smoker, but one day I just asked "What am I doing?!" and quit, withdraws can be though, but getting winded by going up a flight of stairs is worse. I'm feeling better than ever and don't miss the stale smell of cigarettes on all my clothes and belongings.
