In contrast to conventional cigarettes, which contain hazardous substances like tar and carbon monoxide, e-cigarettes don’t actually contain any tobacco. A liquid nicotine solution known as e-liquid or e-juice is used in place of tobacco in e-cigarettes. What is e-liquid exactly? Water, nicotine, flavourings, and a propylene glycol or vegetable glycerin base make up the four main components of e-liquid (or sometimes a mixture of PG and VG).
NICOTINE
Nicotine is the addictive substance present in both traditional cigarettes and e-cigarettes. Nicotine causes the central nervous system to be stimulated and increases heart rate, blood pressure, and breathing. Nicotine increases dopamine levels in the brain, which causes a sense of pleasure to be released. The nicotine level of manufacturers’ products typically ranges from 0 to 36 milligrammes per millilitre. The National Institute on Drug Abuse states that nicotine, despite not being a known carcinogen, is nonetheless addictive and may “prime the brain to become addicted to other substances.”
More than 7,000 different flavours are available, including cherry, coconut, berry blast, fresh apple, sweet tarts, cinnamon, and even tobacco. Although it would be hard to describe every chemical that goes into flavour creation, diacetyl stands out. Diacetyl is frequently used to give popcorn a buttery flavour. Although diacetyl is thought to be completely safe to consume, there is growing evidence that breathing it in can cause the incurable condition obliterative bronchiolitis (OB), often known as “popcorn lung.”
PROPYLENE GLYCOL
Propylene Glycol (PG) is a synthetic liquid manufactured in a lab that the FDA typically considers safe for use in food, medicine, and cosmetics. For performances, it’s also utilised to create fake smoke or fog. It may be especially dangerous for those who have chronic respiratory conditions like asthma and emphysema since it might irritate the lungs and eyes.
GLYCERIN
Liquid glycerin is tasteless, colourless, and odourless. The FDA generally considers it to be safe, like PG. It can be found in a wide variety of goods, including food and drugs (both prescription and over-the-counter).
While several of the compounds mentioned above are recognised to be generally safe in foods and medicines, it is still unknown if breathing in large levels of the chemicals over an extended period of time poses any health hazards. Effects over the long run are almost certain. It is still unclear exactly what they are. They won’t be any good, that much is certain.
HAZARDOUS SUBSTANCES IN FLAVORED VAPE JUICE
According to the National Academies of Sciences, Engineering, and Medicine, there are more than 7,000 vape juice varieties available to e-cigarette users. While several of these are thought to be harmless when consumed in regular food products, they could be dangerous when breathed as aerosols.
Many diverse flavourings added to e-liquids in e-cigarettes contain compounds that may be hazardous to users’ long-term health, according to a 2015 study by Harvard University researchers.
