Facts about vaping that everyone should know: (compiled December 30th, 2015 by Murray B.)
- Vaping is not smoking.
Modern portable vapourizers, including e-cigarettes, use an electric heating element to vapourize a liquid and emit a visible fog. They do not burn anything and do not produce smoke.
- E-cigarette vapour is similar to theatrical fog.
Since the late 1970s, many theatrical foggers have used an electric heating coil to vapourize a “juice” consisting of some type of glycol and/or glycerin and/or water. E-cigarettes and similar devices use an electric heating element to vapourize a fluid composed mainly of propylene glycol and glycerin. E-cigarette “juice” differs from theatrical fogger “juice” in that most types of e-cigarettes “juice” also contain trace amounts of flavouring and/or up to 3.6% nicotine by weight per volume. Theatrical fogger liquids do not usually contain nicotine or flavouring but some types are otherwise more than 96% the same as e-cigarette liquids.
- The long term effect of one component of theatrical fog, propylene glycol, has been studied since at least the late 1940s. The substance was registered with the US FDA in 1950 “for use in hospitals as air disinfectants” and commercial sanitization sprays containing propylene glycol are still available.
- E-cigarette vapour does not normally contain significant amounts of formaldehyde or other toxic combustion products.
Some vaping power packs can be adjusted to produce power levels high enough to burn the fluid. Under those conditions e-cigarette type devices can emit significant amounts of toxic gases but there are few such emissions when those same devices are used at low to moderate power levels.
Most researchers agree with what was written in a letter to the NEJM, “At low voltage (3.3V), we did not detect the formation of any formaldehyde-releasing agents […]”. [The authors of the letter did not explain why they quoted voltage when the heating power of the device would normally be expressed as wattage.]
- Nicotine by itself is not very addictive.
Since first being isolated in 1828, nicotine has been thoroughly tested. In the latter part of the twentieth century nicotine was sometimes prescribed by doctors to treat certain ailments.
Professor Robert Molimard has stated, “We have known nicotine for a century and a half. It has been extracted, synthesized, used as an insecticide, yet we have no observation of its use for addictive purposes.
For patients that had never smoked, nicotine taken by itself has proven to be non-addicting or mildly addicting. Tobacco smoke, on the other hand, may be much more addictive but it also contains many other things in addition to nicotine.
- Nicotine is considered by many experts to be about as harmful as caffeine.
Over the past 180+ years of study, nicotine has proven to be similar to caffeine in its effects and hazards. As Professor Bernd Mayer wrote, “Nicotine and caffeine […] can be compared as consumer products: both have mild adverse effects and may induce moderate dependence.”
- Nicotine is not necessarily a tobacco product.
Nicotine is often extracted from tobacco (Nicotiana tabacum) leaves because the plants are easily grown and readily available. Nicotine can also be extracted from other plants like the Australian pituri shrub (Duboisia hopwoodii), potato, tomato, eggplant and other related flora. Nicotine can even be synthesized in a laboratory. Tobacco is one of many sources of nicotin.
8. Vaping is not as harmful as smoking.
In fact, E-cigarettes were found to be 95% less harmful than tobacco in a peer reviewed study from Public Health England.
