STORY HIGHLIGHTS


  • Yes, there ARE some rules to the Internet, though, for now they're mainly an inside joke

  • Some rules based on pop culture, some have become Web memes

  • Other rules ominously quote Anonymous

  • Is there a need for rules on the vast and wild Web? Depends on where you stand




Editor's note: In the gallery above, we've selected a handful of our favorite Internet rules, or truths. (You might recognize a few.) What are some of yours? Tell us in the comments. We'll feature some of the best on CNN.


(CNN) -- Hello!


Welcome to the Internet. It's a big place, so let me show you around.


You're approaching Oversharing Pass, where residents routinely post too much information. The Facebook Gorge and Twitter Triangle are particularly nefarious time-sucks. Restraint is advised.


Up ahead is Hyperbole Junction, which is the Worst. Spot. Ever. We recommend that you maintain an even keel and stay to the center; the extreme left and right can be dangerous.


And over there is the infamous Lair of Sociopaths, the home of trolls and loners who mercilessly mock everyone who enters their territory. Watch your step: They may trip you up and you'll fall into the Chasm of Lulz.


Our world isn't all dangerous, of course. You may visit Squee City, where images of cute cats and laughing babies fill the landscape. You'll also meet countless kind strangers, hilarious raconteurs and hard-working fact-checkers. They make it all worthwhile.


Hmm. Maybe it would be easier if you had a guide -- you know, some rules to help you find your way.


What, you didn't know there are rules of the Internet?


Of course there are rules. How do you think we maintain order around here?


A parody of rules


That's a joke.


But there really are some rules of the Internet -- even if they, too, began as kind of a joke.


According to the site KnowYourMeme.com, the Rules began around 2006 as a guide for the Internet collective Anonymous and emerged on the old Encyclopedia Dramatica, a bawdy meme catalog. Soon a version emerged on 4chan, an online bulletin board where most users post anonymously, says Jamie Cohen, director of web/digital media at Hofstra University's School of Communication.


"Chris Poole (4chan's founder) kind of designed it, kind of like a Netiquette rules," he says, describing the unspoken code of conduct that lubricates Internet discourse. (Poole has attributed the rules to Gaia Online, a role-playing community.)


But the rules of the Internet deliberately mocked many of those conventions. The self-reflexive parody fit perfectly with its community's attitude, points out Anthony Rotolo, a professor at Syracuse University's School of Information Studies.


"These jokes are meant to comment on something happening in the world," he says. "Later they get accepted as truisms or become a meme."


The absurdity has been reflected even in the supposed number of rules. Though the best-known first version claimed there were 50 rules, only 18 were listed. Number 1 was initially "Do not talk about Rules 2-33"; no Rules 2-33 were on the list.


The sarcastic attitude was reinforced by the kicker found on Encyclopedia Dramatica. It was a parody of Wikipedia's stub language: "This article is crap. You can help by completely re-writing it."


'Fight Club' and Monty Python


Very quickly, the lists started multiplying and expanding, liberally borrowing from comedy, Web culture and math-science tropes. On one list, a few were designated by complex numbers and mathematical symbols. Some were observations; others were directives.




Some have traced the Internet rules to Chris Poole, the founder of 4chan.



Two rules were taken from "Fight Club": "You do not talk about 4chan (or "/b/," 4chan's random, free-wheeling bulletin board) and "You DO NOT talk about 4chan." One version of Rule 6 stated "There is no Rule 6," which is from a Monty Python sketch. Rule 42, "Always bring a towel," was drawn from Douglas Adams' "The Hitchhiker's Guide to the Galaxy" series. (If you have to ask, read the books.) "Profit," Rule 49, came from "South Park."


Other rules went the reverse direction and became part of mainstream culture. Rule 34 -- "If it exists, there is porn of it" -- is likely the most famous. But there's also "Pics or it didn't happen" (Rule 30), "For every given male character, there is a female version of that character; conversely for every given female character, there is a male version of that character" (Rule 63) and, of course, the corollary to Rule 34 -- "If no porn of it exists at the moment, it will be made" (Rule 35).


Most retained a sense of humor, riffing off established rules and occasionally ending with a giggly "No exceptions."


But a handful were, and remain, as serious as a judge -- notably the three directly about Anonymous (commonly Rules 3-5):


- We are Anonymous.


- We are legion.


- We do not forgive, we do not forget.


The overall Internet rules may have started as a joke, but such ominous language from Anonymous speaks to some of the paradoxes of the Web:


Rules? Why do we need some stinkin' rules?


After all, rules can be helpful -- or divisive. They can create community -- or subvert it.


Even Anonymous, the activist group itself, cuts both ways, says Rotolo. When it hacked the extremist Westboro Baptist Church, many people cheered. But when it goes after less unpopular targets, some cry vigilantism.


Cohen says that the rules themselves try to have it both ways. They're funny until someone gets hurt.


They "play more of a game type of role. They can be bent or broken or cheated or moved around, as you would in any game that has no physical reaction," he says. "That doesn't take into account ever the result of real people being affected by this -- such as teenagers, children, anybody who's seeing things that they shouldn't."


He adds, "There's a lot of rules in there that work for (the creators) more than anyone else. Until they become victims of their own thing, they don't know how powerful the rules are."


Evolving from the Wild West


Of course, the Internet isn't that old, and we're still in its Wild West era in many ways. As the technology evolves from a handful of hackers on Usenet bulletin boards to billions of users on officially sponsored sites, the customs -- the rules -- of the Web will evolve with it.


But we're not talking about the kinds of changes that your family makes to the rules of Monopoly (no, Free Parking is NOT for the pool of money acquired via Chance and Community Chest). We're talking something more expansive: All the established customs of our carbon-based life forms, making way for the instantaneous and virtual modes of silicon-based electronics.


Who knows what new rules may be written?


"When you're in the midst of social change, it's impossible to determine where it's going," says Peter S. Vogel, a former programmer who's now a Dallas-based attorney. "And I think we are in the greatest social change in the history of humans, because there are no boundaries of geography or time."


We haven't even sorted out what happens when the differences in local culture meet global technology. Bruce Umbaugh, a philosophy professor at Webster University in St. Louis who teaches a course on philosophy and technology, argues that not all parts of the world are as tolerant or open-minded as Western democracies.



There's a lot of rules in there that work for (the creators) more than anyone else.
Jamie Cohen, Hofstra University



"There are a lot of other places in the world that are actively using the technology of the Internet to control the free communication among citizens, and to identify critics of the government and hurt them," he says. "We need to be mindful in what we advocate from our perspective that the tools that are implemented on the Net are tools for the global Net."


In other words, citizens of other countries already face actual, enforceable rules -- unlike the folkways established by Web users in the West. Witness the frictions of the Arab Spring, or the restrictions of societies such as North Korea.


It's the kind of perspective that provides a different context for the issues raised by a libertarian, anything-goes Internet. It's hard enough to stop "Star Wars" comment boards from devolving into flamebaiting, meme-generating files of NSFW Yodas.


So for now, we're still making our way through the Series of Tubes, and nobody knows where the boundaries lie. We joke, we grimace and we marvel at the creativity of the hive mind. The Internet is a big place, and countless cultures have set up residence. Eventually, what is now humor may lose its zing; what are now customs may become laws.


Will the rules ever become The Rules? Maybe some future generation will figure out the true guideposts of Internet life, and the singularity will be upon us.


Nah. It'll never happen.


What did we miss? Share your rules for the internet below in the comments. We'll feature some of the best on CNN.

Dozens of pro-Dorner protesters rally at LAPD HQ

LOS ANGELES Dozens of protesters rallied outside Los Angeles police headquarters Saturday in support of Christopher Dorner, the former LAPD officer and suspected killer of four who died after a shootout and fire this week at a mountain cabin following one of the biggest manhunts in recent memory.

Protesters told the Los Angeles Times they didn't support Dorner's deadly methods, but objected to police corruption and brutality, and believed Dorner's claims of racism and unfair treatment by the department. Many said they were angered by the conduct of the manhunt that led to Dorner's death and injuries to innocent bystanders who were mistaken for him.

New details of Dorner's final hours




Michael Nam, 30, who held a sign with a flaming tombstone and the inscription "RIP Habeas Corpus," said it was "pretty obvious" police had no intention of bringing Dorner in alive.

"They were the judge, the jury and the executioner," Nam said. "As an American citizen, you have the right to a trial and due process by law."

During the hunt for Dorner, LAPD Chief Charlie Beck called for Dorner's surrender and said he didn't want to see the suspect or anyone else injured.

Dorner was already believed to have killed three people when he was cornered Tuesday at the cabin near Big Bear Lake, and during the standoff shot and killed a San Bernardino County sheriff's deputy, authorities said.

Reporter records gunfight in Dorner capture effort




Only after calls for surrender and use of milder tear gas did deputies launch pyrotechnic gas canisters into the cabin, and the subsequent fire was not intentional, the Sheriff's Department said.

Dorner died of a self-inflicted gunshot wound at the end of the standoff, sheriff's officials said.

The 33-year-old has already inspired a burgeoning subculture of followers. While most don't condone killing, they see him as an outlaw hero who raged against powerful forces of authority, and some even question whether he really died.

Tributes include a ballad titled "El Matapolicias," or "The Police Killer," penned by a Mexican crooner with lyrics paying homage to Dorner, and a YouTube clip showing excerpts from a video game titled "Christopher Dorner's Last Stand Survival Game" whose opening frame declares him "A True American Hero."

Meteor Blast 'Something We Only Saw in Movies'












A day after a massive meteor exploded over this city in central Russia, a monumental cleanup effort is under way.


Authorities have deployed around 24,000 troops and emergencies responders to help in the effort.


Officials say more than a million square feet of windows -- the size of about 20 football fields -- were shattered by the shockwave from the meteor's blast. Around 4,000 buildings in the area were damaged.


The injury toll climbed steadily on Friday. Authorities said today it now stands at more than 1,200. Most of those injuries were from broken glass, and only a few hundred required hospitalization.


According to NASA, this was the biggest meteor to hit Earth in more than a century. Preliminary figures suggest it was 50 feet wide and weighed more than the Eiffel Tower.










SEE PHOTOS: Meteorite Crashes in Russia


NASA scientists have also estimated the force of the blast that occurred when the meteor fractured upon entering Earth's atmosphere was approximately 470 kilotons -- the equivalent of about 30 Hiroshima bombs.


Residents said today they still can't believe it happened here.


"It was something we only saw in the movies," one university student said. "We never thought we would see it ourselves."


Throughout the city, the streets are littered with broken glass. Local officials have announced an ambitious pledge to replace all the broken windows within a week. In the early morning hours, however, workers could still be heard drilling new windows into place.


Authorities have sent divers into a frozen lake outside the city, where a large chunk of the meteor is believed to have landed, creating a large hole in the ice. By the end of the day they had not found anything.


They are not the only ones looking for it.


Meteor hunters from around the world are salivating at what some are calling the opportunity of a lifetime. A small piece of the meteor could fetch thousands of dollars and larger chunks could bring in even hundreds of thousands.

False memories prime immune system for future attacks









































IN A police line-up, a falsely remembered face is a big problem. But for the body's police force – the immune system – false memories could be a crucial weapon.












When a new bacterium or virus invades the body, the immune system mounts an attack by sending in white blood cells called T-cells that are tailored to the molecular structure of that invader. Defeating the infection can take several weeks. However, once victorious, some T-cells stick around, turning into memory cells that remember the invader, reducing the time taken to kill it the next time it turns up.












Conventional thinking has it that memory cells for a particular microbe only form in response to an infection. "The dogma is that you need to be exposed," says Mark Davis of Stanford University in California, but now he and his colleagues have shown that this is not always the case.












The team took 26 samples from the Stanford Blood Center. All 26 people had been screened for diseases and had never been infected with HIV, herpes simplex virus or cytomegalovirus. Despite this, Davis's team found that all the samples contained T-cells tailored to these viruses, and an average of 50 per cent of these cells were memory cells.












The idea that T-cells don't need to be exposed to the pathogen "is paradigm shifting," says Philip Ashton-Rickardt of Imperial College London, who was not involved in the study. "Not only do they have capacity to remember, they seem to have seen a virus when they haven't."












So how are these false memories created? To a T-cell, each virus is "just a collection of peptides", says Davis. And so different microbes could have structures that are similar enough to confuse the T-cells.












To test this idea, the researchers vaccinated two people with an H1N1 strain of influenza and found that this also stimulated the T-cells to react to two bacteria with a similar peptide structure. Exposing the samples from the blood bank to peptide sequences from certain gut and soil bacteria and a species of ocean algae resulted in an immune response to HIV (Immunology, doi.org/kgg).












The finding could explain why vaccinating children against measles seems to improve mortality rates from other diseases. It also raises the possibility of creating a database of cross-reactive microbes to find new vaccination strategies. "We need to start exploring case by case," says Davis.












"You could find innocuous pathogens that are good at vaccinating against nasty ones," says Ashton-Rickardt. The idea of cross-reactivity is as old as immunology, he says. But he is excited about the potential for finding unexpected correlations. "Who could have predicted that HIV was related to an ocean algae?" he says. "No one's going to make that up!"

US cruise ship passengers' parting gift: bathrobes






WASHINGTON: The 4,000-plus exhausted passengers who lived a hellish four-day ordeal aboard the powerless and drifting Carnival Triumph cruise ship won't be left completely empty handed.

The cruise company is making a gift to the travelers of the bathrobes they were using on the ship, the company announced Friday.

"Of course the bathrobes for the Carnival Triumph are complimentary," it said in a tweet on the official @carnivalcruise account.

But the announcement has been received with less than full-throated cheers.

"Who wants a stinky robe?!" tweeted a reporter in North Carolina, Astrid Martinez, while another user of the social media site, Natalie Eshaya, enthused sarcastically, "Oh how generous."

Another skeptic, Paul Nather, wondered "What do you think the going rate for a Carnival cruise bathrobe will be on eBay tomorrow?"

The white bathrobe has become an unlikely symbol of the nightmare of the cruise-goers, who donned them to attract attention as they stood on the drifting ship.

Others used the white terrycloth as a canvas to write messages, with one passenger proclaiming, "I survived Carnival's triumph redbags" -- a reference to the bags that substituted for toilets.

The Triumph docked Friday morning in the port of Mobile, Alabama. It had originally been scheduled to return to port early Monday after a weekend stop in Cozumel in Mexico, before an engine room blaze left the massive vessel without electricity to power the kitchens, toilets, and other necessities.

Man arrested in Alaska Coast Guard base deaths

ANCHORAGE, Alaska An Alaska man was arrested Friday in last year's shooting deaths at a Coast Guard air station on Kodiak Island that left two employees dead, the U.S. attorney said.

James Michael Wells of Kodiak is accused in a federal murder complaint of killing Petty Officer 1st Class James Hopkins and retired Chief Boatswain's Mate Richard Belisle on April 12.

Another Coast Guard member found the victims shortly after the two would have arrived for work at the station, which monitors radio traffic from ships and planes and is home to cutters, helicopters and rescue swimmers that aid mariners in the Bering Sea and Pacific Ocean. Their bodies were found in the rigger building, where antennas are repaired.

FBI agents immediately flew to Kodiak Island from Anchorage, about 250 miles away, to investigate the case as a double homicide. Few details were released in the weeks after the deaths.

Wells' arrest came after "an extensive investigation" led by the FBI and the Coast Guard Investigative Service, with help from the Alaska State Troopers, U.S. Attorney Karen Loeffler said in a statement.

Wells is expected to appear in court next week in Anchorage, Loeffler said.

No one was immediately reachable by phone Friday evening at the U.S. attorney's office to provide additional details.

Hopkins, 41, was an electronics technician from Vergennes, Vt. Belisle, 51, was a former chief petty officer who continued service to the Coast Guard as a civilian employee.

Carnival Cruise Ship Hit With First Lawsuit












The first lawsuit against Carnival Cruise Lines has been filed and it is expected to be the beginning of a wave of lawsuits against the ship's owners.


Cassie Terry, 25, of Brazoria County, Texas, filed a lawsuit today in Miami federal court, calling the disabled Triumph cruise ship "a floating hell."


"Plaintiff was forced to endure unbearable and horrendous odors on the filthy and disabled vessel, and wade through human feces in order to reach food lines where the wait was counted in hours, only to receive rations of spoiled food," according to the lawsuit, obtained by ABCNews.com. "Plaintiff was forced to subsist for days in a floating toilet, a floating Petri dish, a floating hell."

The filing also said that during the "horrifying and excruciating tow back to the United States," the ship tilted several times "causing human waste to spill out of non-functioning toilets, flood across the vessel's floors and halls, and drip down the vessel's walls."


Terry's attorney Brent Allison told ABCNews.com that Terry knew she wanted to sue before she even got off the boat. When she was able to reach her husband, she told her husband and he contacted the attorneys.


Allison said Terry is thankful to be home with her husband, but is not feeling well and is going to a doctor.

"She's nauseated and actually has a fever," Allison said.


Terry is suing for breach of maritime contract, negligence, negligent misrepresentation and fraud as a result of the "unseaworthy, unsafe, unsanitary, and generally despicable conditions" on the crippled cruise ship.


"Plaintiff feared for her life and safety, under constant threat of contracting serious illness by the raw sewage filling the vessel, and suffering actual or some bodily injury," the lawsuit says.


Despite having their feet back on solid ground and making their way home, many passengers from the cruise ship are still fuming over their five days of squalor on the stricken ship and the cruise ship company is likely to be hit with a wave of lawsuits.


"I think people are going to file suits and rightly so," maritime trial attorney John Hickey told ABCNews.com. "I think, frankly, that the conduct of Carnival has been outrageous from the get-go."


Hickey, a Miami-based attorney, said his firm has already received "quite a few" inquiries from passengers who just got off the ship early this morning.


"What you have here is a) negligence on the part of Carnival and b) you have them, the passengers, being exposed to the risk of actual physical injury," Hickey said.


The attorney said that whether passengers can recover monetary compensation will depend on maritime law and the 15-pages of legal "gobbledygook," as Hickey described it, that passengers signed before boarding, but "nobody really agrees to."


One of the ticket conditions is that class action lawsuits are not allowed, but Hickey said there is a possibility that could be voided when all the conditions of the situation are taken into account.


One of the passengers already thinking about legal action is Tammy Hilley, a mother of two, who was on a girl's getaway with her two friends when a fire in the ship's engine room disabled the vessel's propulsion system and knocked out most of its power.


"I think that's a direction that our families will talk about, consider and see what's right for us," Hilley told "Good Morning America" when asked if she would be seeking legal action.

Sand-grain-sized drum extends reach of quantum theory


































The banging of a tiny drum heralds the intrusion of the weird world of quantum mechanics into our everyday experience. Though no bigger than a grain of sand, the drum is the largest object ever to have been caught obeying the uncertainty principle, a central idea in quantum theory.












As well as extending the observed reach of quantum theory, the finding could complicate the hunt for elusive gravitational waves : it suggests that the infinitesimal motion caused by these still-hypothetical ripples in spacetime could be overwhelmed by quantum effects.













The uncertainty principle says that you cannot simultaneously determine both a particle's exact position and momentum. For example, bouncing a photon off an electron will tell you where it is, but it will also change the electron's motion, creating fresh uncertainty in its speed.












This idea limits our ability to measure the properties of very small objects, such as electrons and atoms. The principle should also apply to everyday, macroscopic objects, but this has not been tested – for larger objects, the principle's effects tend to be swamped by other uncertainties in measurement, due to random noise, say.











Quantum drum













To extend the known reach of the uncertainty principle, Tom Purdy and colleagues of the University of Colorado, Boulder, created a drum by tightly stretching a 40-nanometre-thick sheet of silicon nitride over a square frame with sides of half a millimetre – about the width of a grain of sand. They placed the drum inside a vacuum chamber cooled to a few degrees above absolute zero, minimising any interference by random noise.












By continuously firing a stream of photons at the drum they were able to get increasingly precise measurements of the position of the skin at any moment. However, this also caused the skin to vibrate at an unknown speed. When they attempted to determine its momentum, the error in their measurement had increased – just as the uncertainty principle predicts.












"You don't usually have to think about quantum mechanics for objects you can hold in your hand," says Purdy.












That the uncertainty principle holds sway at such a large scale could affect the hunt for gravitational waves, which are predicted by Einstein's theory of general relativity but have never been detected.











Mitigation strategy












Gravitational wave detectors look for very slight changes in the distance between two test masses caused by passing spacetime ripples. Purdy says his team's experiment confirms long-held suspicions that quantum uncertainty could overwhelm these very small changes.













Now he and others can use the drum to explore more advanced measurement techniques to mitigate the effects. For example, uncertainty in an object's momentum could lead to future uncertainty in its position and there should be ways to minimise such knock-on effects. "You can't avoid the uncertainty principle, but you can in some clever ways make it [such that] increasing the momentum doesn't add back to the uncertainty in position at a later time," says Purdy.











His experiment is a neat demonstration of the breakdown of the traditional notion that the atomic world is quantum while the macroscopic world is classic, says Gerard Milburn of the University of Queensland in Brisbane, Australia, who was not involved in the work. Previous, attempts to blur the quantum-classical divide have involved entangling diamonds and demonstrating quantum superposition in a strip of metal.













Despite these feats, Milburn doesn't rule out the prospect of a breakdown on really large scales. "Of course maybe one day we will see quantum mechanics fail at some scale. Testing it to destruction is a good motivation for going down this path," he says.

Smoking out tobacco: The rise of the e-cig






PARIS: The camera zooms in on a bearded man dragging on a cigarette and blowing out a thick cloud of smoke with what seems to be great satisfaction.

It resembles the TV smoking ads of yesteryear, now banned in most of the world, yet this modern-day offering is approved for American television viewers.

"You know what the most amazing thing about this cigarette is? It isn't one," explains a narrator as the modern-day Marlboro Man fixes the viewer with a broody stare before returning the reusable smoke to a container that resembles the traditional pocket-sized cardboard pack.

The NJOY "cigarette" is electronic -- its tip lights up with the help of an LED and what appears to be smoke is actually water vapour.

The actor is not smoking, but "vaping".

"Cigarettes, you have met your match," proclaims the ad for a product that claims to mimic "the look, feel and flavour of the real thing" -- minus the tar, ash, smoke and most toxins.

NJOY is one of a flurry of e-cigs entering the market as tobacco prices skyrocket and smokers become ever more concerned about the toxins they inhale.

But the jury is still out on whether the gadgets are safe or not.

"Without question, e-cigarettes are safer than traditional tobacco cigarettes," said Joel Nitzkin, of the American Association of Public Health Physicians.

"They deliver nicotine, with only the tiniest traces of other toxic chemicals."

But there are concerns that these battery-driven alternatives, officially called electronic nicotine delivery systems (ENDS), may pose health hazards we are not even aware of yet -- just like cigarettes before their ill-effects became clear.

"The safety of ENDS has not been scientifically demonstrated," the World Health Organisation said in response to a query.

"The potential risks they pose for the health of users remain undetermined."

The UN's health organ said some testing "suggests the presence of other toxic chemicals, aside from nicotine", and "strongly advised" consumers not to use them.

E-cigs first emerged in China in 2003 as an alternative to tobacco, which kills nearly six million people each year.

Just like their predecessors in the 1950s and 60s, electronic cigarettes are being advertised with attractive women and rugged, virile men -- hinting at a better, more popular you.

It's a strategy that seems to work.

A study in the American Journal of Preventive Medicine (AJPM) last month said 80 percent of users questioned in the United States, Britain, Canada and Australia believed e-cigarettes to be less harmful than their tobacco counterparts.

NJOY chief executive Craig Weiss told AFP that industry predictions are for electronic cigarette sales, which have doubled in the United States every year since 2008, to reach $1 billion (about 750,000 euros) in 2013.

"Growth in the category has occurred as a result of the millions of smokers who are actively seeking an alternative to cigarettes," he said by email.

The company would not comment on the health aspects.

According to Nitzkin, the hazard posed by traditional tobacco cigarettes is about 100 times higher than today's smokeless tobacco alternatives.

"When burned, cigarettes create a tarry residue that sticks to the inside of the smallest bronchial tubes of the lungs and in the alveoli, where the body absorbs the oxygen and releases the carbon dioxide.

"This tarry residue stays in place 24 hours a day, seven days a week for the life of the smoker," he said -- a side-effect that ENDS do not have.

Yet the European Respiratory Society said this month it could not classify e-cigs as a safe alternative to smoking, and stressed the principle that tobacco users "should not trade one carcinogenic product for another".

Last month, the UK's Advertising Standards Authority banned an ad for an e-cigarette, Nicolites, saying: "claims that the product was not harmful had not been substantiated".

Some researchers have also expressed concerns that non-smokers may get hooked on nicotine through e-cigarette use, or that the gadget would keep people addicted to nicotine who might otherwise have quit.

Nicotine can be harmful to children, pregnant women and adults with heart disease.

A recent study among 3,400 high school pupils in France showed that 12 percent of 15-to-16-year-olds who claimed never to have smoked before had experimented with ENDS, and 19 percent of 17-year-olds.

"As a doctor, I cannot recommend the electronic cigarette," lung specialist Bertrand Dautzenberg told AFP recently at the Pitie-Salpetriere hospital in Paris.

"But I would not interfere with a smoker who wants to take it up. With a cigarette, there is a 50 percent chance of killing oneself. With the electronic cigarette, we aren't too sure yet, but it is probably less," he said.
