Or maybe the current language is not supported

  • 00:01

    I was sitting in Bush Intercontinental Airport in Houston recently, on my way to a small

  • 00:06

    scientific conference where I gave a short talk on my current project.

  • 00:11

    As I'm sitting, waiting for boarding time, a very large man sits down right next to me

  • 00:16

    and pulls a cigarette out of his pocket, takes a long drag on it, and exhales deeply.

  • 00:22

    Now I'm old enough to remember the no smoking warnings being a bit of a novelty, but I hadn't

  • 00:28

    seen anyone smoke in an airport in a few decades, so I admit I was shocked.

  • 00:33

    The gate attendant sprinted over to ... I don't know what she had planned, but there

  • 00:38

    was murder in her eye.

  • 00:40

    The guy smirks and says, "It's not a real smoke, it's an electronic cigarette... see,

  • 00:45

    no flame, no second hand smoke."

  • 00:48

    The gate attendant explained, with poorly contained rage, that the FAA and the airline

  • 00:53

    both forbid the use of these devices.

  • 00:57

    The guy looked equally outraged, but put the e-cig back in its case as he started debating

  • 01:03

    federal policy with reference to nicotine gum, prescription drugs, and medical needs.

  • 01:09

    People have been asking me to address the controversy surrounding these very new alternatives

  • 01:13

    to smoking cigarettes.

  • 01:15

    It's not an altogether easy topic to cover.

  • 01:18

    There just isn't much data so far and what little evidence does exist is contradictory

  • 01:23

    on the health effects.

  • 01:25

    The e-cigarette was first described in a patent attributed to Herbert Gilbert in 1963, but

  • 01:32

    the modern commercial version has only been around since 2003, invented by Chinese pharmacist

  • 01:39

    Hon Lik.

  • 01:40

    In 2005, it was approved for export outside of China by a company called Ruyan and the

  • 01:47

    international patent was filed only 5 years ago.

  • 01:51

    In such a short time, they have really caught on, and are already presenting legislators

  • 01:55

    with difficult choices.

  • 01:58

    Should they be treated as drugs and devices, and regulated in the same way as medical inhalers,

  • 02:03

    since they do deliver nicotine, or should they be regulated as a smokeless tobacco product,

  • 02:09

    which in a way they are?

  • 02:11

    The difference is whether they meet stringent safety and purity criteria or merely the basic

  • 02:16

    standards of an agricultural product.

  • 02:19

    The US Food and Drug Administration strongly suggested that should be regulated as a combo

  • 02:25

    of drug and medical device.

  • 02:28

    Late last year they were over-ruled.

  • 02:31

    Starting in 2012, e-cigarettes will be regulated in the US by the FDA as though they were cigarettes,

  • 02:37

    following much more lax requirements for manufacturing and testing.

  • 02:41

    This benefitted manufacturers, because it keeps costs down, but probably doesn't do

  • 02:46

    anything good for consumers.

  • 02:49

    We should take a very quick detour to explain how they work.

  • 02:53

    There are two main elements in the electronic cigarette.

  • 02:56

    First the juice, which is solution of propylene glycol or glycerin base, flavor, nicotine,

  • 03:03

    and water.

  • 03:04

    The PG has been used for decades in nebulizers with minimal risk, and the FDA rates it as

  • 03:10

    GRAS, or generally recognized as safe.

  • 03:14

    The second element is the mini-vaporizer, which works by either heat or vibration to

  • 03:19

    generate a vapor of the juice.

  • 03:22

    The juice is inhaled by the smoker as vapor into mouth and lungs, where it condenses and

  • 03:27

    is absorbed into the bloodstream.

  • 03:29

    It all sounds like a safer, more convenient, less toxic way to avoid smoking those dreaded

  • 03:34

    cancer sticks.

  • 03:36

    The nicotine delivery works on very different time scale than cigarettes, and the delivered

  • 03:41

    dose is quite different.

  • 03:43

    If we measure nicotine derivatives in the blood of a cigarette smoker, there's an initial

  • 03:48

    spike within 5 minutes.

  • 03:50

    The e-cigarette can take up to 30 minutes to reach that initial spike.

  • 03:55

    The combustion products of cigarettes, and the particle size of delivery is actually

  • 03:59

    very different from liquid vapor delivery, so the e-cigarette is much more analogous

  • 04:04

    to a nicotine gum or patch product.

  • 04:08

    It's been suggested that the majority of the nicotine is actually being absorbed in the

  • 04:12

    gastrointestinal tract, essentially drunk as the juice condenses, passes into the stomach

  • 04:19

    and eventually the liver.

  • 04:21

    This is an important difference, because the liver acts as a filter for toxins, where in

  • 04:25

    smoked cigarettes, the lungs absorb the nicotine without passing first through that filtration.

  • 04:32

    The second paradox is that the delivered dose can be highly variable in e-cigarettes, and

  • 04:37

    they may actually be, if this is even possible, more likely to promote physical addiction

  • 04:43

    to nicotine than cigarettes.

  • 04:46

    What about secondhand smoke, or in this case, vapor?

  • 04:50

    Well, the exhaust of an e-cigarette doesn't contain tar, except when it does.

  • 04:56

    That's right, in a few cases the juice was contamined with some byproducts of its manufacture.

  • 05:03

    The cheapest place to get bulk nicotine is from tobacco extracts.

  • 05:09

    Sometimes those extracts aren't that purified, and some cancer-promoting substances other

  • 05:14

    than nicotine are co-purified.

  • 05:18

    The manufacturer acted very surprised when the lab tests were presented, but I suspect

  • 05:23

    that it was not that unexpected.

  • 05:26

    The risk is still relatively low in comparison to cigarettes, but higher than not breathing

  • 05:31

    in second-hand smoke.

  • 05:34

    What else is present in the exhaust of e-cigarettes?

  • 05:37

    Well, nicotine, and really quite a lot of it.

  • 05:41

    People around you can still be inadvertantly exposed to an inhaled stimulant, nicotine.

  • 05:47

    Nicotine is quite probably the most addictive drug produced by a plant.

  • 05:51

    It causes long term changes in neural plasticity, affecting learning, behavior, and possibly

  • 05:56

    promoting other addictive behaviors.

  • 05:59

    Unlike cannabis, where the gateway drug effect is not well supported, nicotine almost certainly

  • 06:05

    promotes the development of other addictions like alcohol and eating disorders.

  • 06:11

    As a friend of mine, who studies nicotine's effect on the brain describes it, nicotine

  • 06:15

    makes you neurotic.

  • 06:17

    That's because it increases the level of several neurotransmitters in your central nervous

  • 06:22

    system.

  • 06:23

    It stimulates the release of adrenaline and global changes in brain activity.

  • 06:27

    Long term, it affects the ability of your genes to be turned on and turned off by a

  • 06:31

    specific mechanism.

  • 06:33

    There's also a correlation to schizophrenia and some other conditions.

  • 06:37

    I would prefer that if you're addicted to cigarettes that you could stop cold turkey,

  • 06:41

    and simply never start again.

  • 06:43

    I know that may not be practical.

  • 06:45

    Research shows that nicotine replacement therapies can be effective at helping you quit.

  • 06:51

    That leads us to the final question of this video.

  • 06:54

    Are e-cigarettes effective at helping people quit their addiction?

  • 06:58

    The evidence so far is inconclusive.

  • 07:01

    People certainly substitute the e-cigarette for the cancer stick once they pick it up,

  • 07:06

    but it's still unclear if they can then wean themselves off the substitute.

  • 07:10

    I think in summary I think you're better off with another nicotine replacement therapy,

  • 07:14

    not e-cigarettes.

  • 07:16

    If you are interested in quitting, try the gum, the inhaler, or the patch.

  • 07:20

    Talk with a physician and take their advice.

  • 07:25

    E-cigarettes might end up as a safe alternative with better regulation, further technological

  • 07:29

    improvements, and more research, but right now they're probably not a great idea.

  • 07:35

    Keep in mind that they still aren't safe around kids or the elderly or people sensitive to

  • 07:40

    nicotine.

  • 07:41

    What worries me the very most about this new product is the hipster angle.

  • 07:45

    I'm worried that they'll become a popular new trend.

  • 07:49

    Public health agencies, medical organizations, and government have been combatting the rise

  • 07:53

    in smoking with great progress over the last few decades.

  • 07:57

    Fewer and fewer kids are making the big mistake of picking up the lifetime habit.

  • 08:02

    I would hate for some new marketing spin, some new media campaign or underground movement

  • 08:08

    to reverse all that progress.

  • 08:11

    It's estimated that smoking in the US results in 160 billion dollars in health care costs,

  • 08:17

    lost worker productivity, and indirect effects, to say nothing of the grief of a family that

  • 08:22

    loses mom or dad too soon to lung cancer, COPD or heart disease.

  • 08:28

    I'd support any legislation that promotes updated education for the general public,

  • 08:33

    but especially school-age kids, about the dangers of not just smoking, but also other

  • 08:37

    nicotine products.

  • 08:39

    If you have a young person in your life, take a minute to talk openly and honestly about

  • 08:44

    why smoking or other addictions are a bad thing.

  • 08:48

    Immaturity and the kind of bad choices we all make at that age shouldn't have life-long

  • 08:52

    consequences, but they do.

  • 08:55

    Do what you can to educate them so they can see the path ahead.

  • 08:58

    Do it honestly, but do it now.

  • 09:02

    Thanks for watching.
