Smoking vs Vaping

Smoking vs Vaping


Cigarettes and Marijuana and 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 in 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 explain in our video “Your Brain on Marijuana” here. Smoking only takes 6 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 consist
of partially burned particles which creates tar in your body, has cancer causing effects,
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 controlled 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
185-210 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
e-liquid contains water, nicotine, a base and occasionally flavourings, and vaporizes
at a much lower temperature. But 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 also used in theatrical smoke, is known
to cause irritation to the eyes and respiratory infections. So what’s going to 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. E-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 microwaveable 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. E-cigarettes with added flavouring
(such as blueberry or grape) have been found to contain other harmful chemicals. And second
hand smoke is still an issue; exhaled particles from vaporizers known as “ultrafine particles”
are known to affect pulmonary health. Others are worried that because these “e-cigs”
are deemed healthier that they are becoming more appealing for young people. A study reported
that continued use of e-cigarettes for teens in grade 6 – 12 had increased from 6% – 20%
over 3 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 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

  2. 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 โœ‹

  4. Iโ€™ve given up on vaping. Itโ€™s just one big headache having to deal with inefficient poorly made overpriced equipment constantly. Felt like a damn tweaker always messing with them.

  5. Itโ€™s kinda scary to think about. Thereโ€™s been so many times where something dangerous became a trend and they didnโ€™t know until later. Like tanning butter, glow in the dark paint, cigarettes, and possibly vape. Something people donโ€™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 wasnโ€™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. Itโ€™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.

  6. 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

  7. NEW LUNG ILLNESS LINKED TO VAPING IN THE US

    Over 100 cases of a lung illness which is new to the knowledge of health professionals are reported in the US. It is associated with vaping and e-cigarettes. A large number of patients are teens and young adults. The Centers for Disease Control and Prevention said that the health departments of California, Illinois, Indiana, Minnesota and Wisconsin have confirmed cases of this pulmonary illness.

  9. Why cant people understand, it is simply flavoured water that is heated to make steam, like a tea pot. 0 percent nicotine, it is simply 100% safe! And it also doesn't stick to you like smoke. It is just something that relaxes you.. but then people say even if there is nothing wrong with it, it is fun so it is addictive so people say to much of anything is bad for you, not true bro, if it isn't harmful in any type of way.. there is nothing wrong with it!

    This are the amount of people who agree:
