Smoking vs Vaping

cigarettes and marijuana have been used for centuries but only recently has the process of vaporizing these substances become popular so what does science have to say about this technology is it actually better for you when smoking normally the heat from fire causes substances to change from a solid state to a vapor in cigarettes this releases nicotine which is absorbed into your bloodstream through the lungs causing increased heart rate constricted blood vessels release of dopamine in the brain and feelings of alertness but because nicotine is a stimulant once it’s no longer present you crash and crave more which ultimately leads to addiction and many people in the case of marijuana the active component THC is aerosolized and follows the same pathway into your body but with different effects which we explained in our video your brain on marijuana here smoking only takes six seconds for the active compounds to reach your nervous system unlike chewing tobacco or eating edible marijuana which takes much more time but you have to inhale smoke in the process this smoke consists of partially burned particles which creates tar in your body has cancer-causing affects blackens teeth and destroys taste buds this is where vaping comes in if you can heat the active components enough to become aerosolized without starting a combustion reaction with the other compounds then you theoretically get fast effects without the damage of smoke inhalation vaping typically involves a glass or metal chamber which has an electrical current passing through it this way it can heat to a control temperature creating a vapor with minimal combustion meaning you inhale much less smoke for marijuana users vaporizers have become popular as the plant material can be heated to a specific temperature usually between 185 to 210 degrees Celsius allowing just the THC containing vapor to be extracted for e-cigarettes using a liquid solution instead of dried tobacco has become popular this eliquid contains water nicotine a bass and occasionally flavorings and vaporizes at a much lower temperature this is where things get tricky the e-liquid contains a base similar to that used in cosmetics and food which helps maintain moisture without creating sogginess one common base called propylene glycol which is used in theatrical smoke is known to cause irritation to the eyes and respiratory infections so what’s gonna happen after prolonged inhalation in e-cigarettes scientists are still studying these effects and even though in America the FDA has given the seal of approval much is still unknown a liquid can also differ greatly between manufacturers with barely any regulation for additives some have been found to contain diacetyl a chemical that is known to give butter its buttery taste inhalation of this chemical can lead to scarring in the lungs known as popcorn lung named after hundreds of workers inhaled the chemical in a microwavable popcorn factory and suffered irreversible lung damage this is an example of how the lack of quality control in e-cigarettes should be a significant concern but current evidence does indicate that vaporizers administer nicotine with far less adverse effects due to decreased carcinogenic products and smoke inhalation but less harmful does not mean safe hee cigarettes with added flavorings such as blueberry or grape have been found to contain other harmful chemicals and secondhand smoke is still an issue exhale particles from vaporizers known as ultrafine particles are known to affect pulmonary health others are worried that because these ecigs are deemed healthier that they’re becoming more appealing for young people a study reported that continued use of e-cigarettes for teens in grades 6 to 12 had increased from 6% to 20% over three years on the other hand much of the information we have on the adverse effects of smoking comes from long-term studies with cancers appearing much later in life since vaporizer use is relatively new we simply don’t have the same access to longitudinal studies so we’ll wait to see what the future brings special thanks to audible for supporting this episode and giving you a free audiobook at audible.com/asap this week we wanted to recommend the book Elon Musk Tesla SpaceX and the quest for our fantastic future by ashley vance which explores the full spectacle and arc of the geniuses life work and vision you can get a free copy at audible.com/asap or any others of your choice from a massive selection we love them as they’re great when you’re on the go don’t forget to ask your burning questions and subscribe for more weekly science videos [Music]

  1. I heard a person in my school was caught vaping

    she is in 7th grade, like me. And she my friend’s friend

  2. While i vaped, after 2 or 3 months i started to have negative symptoms that i never had in years of smoking classic tobacco. Quit vaping, after 2 days those symptoms gone. In my opinion all that vape propaganda is total bullshit. Chemicals. I'd rather burn the plant, than inhale those laboratory poisons.

  3. the thing about vaping and the butter thingy, and that is why the eu has set strict laws for produceres, about what chemicals they can use

  4. A skit.
    Kid: MoM Why’D yOU TaKE mY JUul?
    Mom: I had to you’re addicted.
    Kid. Youre a whoreeeeee.
    Mom: You dont mean that!
    Kid:Mom it cost 60 dollars and it was tootie fruity!
    Mom: *Hits juul*

  5. CAN 👏 WE 👏 TAKE 👏 A 👏 SEC 👏 TO 👏 THAT 👏 THIS 👏 VIDEO 👏 IS 👏 4 👏 MINUTES 👏 TWENTY 👏 SECONDS 👏

  6. Sometimes this video is so stupidly obvious it makes me cringe. Like vaping us so much better. Not maybe better because there's evidence for it. IT IS BETTER. Like are you trying to confuse or scare people? Pathetic. Your video on the mathematical existence of god made even less since. Just stop. Please ✋

  7. I’ve given up on vaping. It’s just one big headache having to deal with inefficient poorly made overpriced equipment constantly. Felt like a damn tweaker always messing with them.

  8. It’s kinda scary to think about. There’s been so many times where something dangerous became a trend and they didn’t know until later. Like tanning butter, glow in the dark paint, cigarettes, and possibly vape. Something people don’t talk about often is the DDT epidemic that took place decades ago in the United States. It was the first main pesticide and before Americans knew it wasn’t fit for human inhalation, it was spraying in masses. They resulted in the decrease in population of many different species. Bald eagles were put on the endangered list because the DDT caused the female eagles to somehow lay eggs with abnormally thin egg shells. So when the female bird would sit on the eggs, they would crack. It’s not something people talk about but should be taught in high school science. If vape is similar to DDT then I worry for what unknown effects it may cause on our generations to come.

  9. Ive settled with the good ole essential oil pens, they make you happy and help with anxiety and all that, and have no nicotine or other chemicals like diactyl
