Vapes are also known as e-cigarettes, vape pens, or electronic nicotine delivery systems (ENDS). They have a cartridge or tank that holds liquid and has a heating element to turn the liquid into breathable particles, or aerosol.
Nicotine and other chemicals in e-liquids can harm the lungs by damaging or narrowing the tubes that bring air in and out of them. They can cause lung scarring and bronchiolitis obliterans, or “Relevant Vapes.”
E-liquids
E-liquids are the liquid that goes into a vape pen to give it flavour and nicotine (if you want it). The vapor produced by these devices is made from glycerol, propylene glycol and other ingredients. The glycerol and propylene glycol are tasteless, so they carry the flavour, while nicotine provides a nicotine hit. They are available in a wide variety of strengths and flavours, with some brands offering zero nicotine e-liquids.
The e-liquids used in Relevant Vapes are mixed from four different parts: vegetable glycerin, propylene glycol, nicotine and flavourings. Vegetable glycerin is a clear liquid that produces large clouds and does not have a distinct smell. Propylene glycol is a tasteless, colourless liquid that carries the flavour and does not produce as much vapor. Nicotine is a psychoactive compound that stimulates the adrenal glands and increases levels of a chemical messenger called dopamine, which gives feelings of pleasure. It is also addictive and can cause lung damage.
Pod devices
Pod devices, also called pod kits, are small, draw-activated e-cigarettes that have a battery device and a pod filled with vape juice. These are a great option for smokers trying to quit smoking or those looking for a convenient, portable vaping experience.
Usually, these devices use pods that are pre-filled with a specific e-liquid. This simplifies the decisions that users have to make and allows them to start vaping as quickly as possible. However, they are less customizable and may have a limited range of flavors to choose from.
Alternatively, you can purchase refillable pod systems, which allow you to select a variety of e-liquid flavors. These are more expensive but they provide more options and flexibility. They are also environmentally friendly and less wasteful than disposable devices. Some pod systems have features such as adjustable airflow and replaceable coils, which adds to the convenience of these devices. Other features, such as variable wattage and dual firing modes, are available in some models.
E-cigarettes
E-cigarettes are a popular way to consume nicotine. These devices consist of four components: a battery, a cartridge or tank that holds liquid, a heating element or atomizer, and a mouthpiece. The liquids and aerosols contain a variety of chemicals, including nicotine. These chemicals have a range of effects, from the irritation of the lungs to the disruption of normal cell function.
The e-cigarette industry aggressively markets its products to young people. They offer appealing flavors and college scholarships, and they advertise in magazines, on TV, and on the Internet. Some companies even create pop-up stores in schools and malls.
A recent study found that a celebrity endorsement on an e-cigarette social media page increased the number of young adults who reported using the product. In addition, some news events seem to have a disproportionate impact on vape sales. Future research may detail how this happens and suggest strategies for intervening around disproportionate responses to news events.
ENDS
ENDS are devices that use electronic liquid to vaporise nicotine and other ingredients and produce an aerosol that is inhaled. They may be manufactured to look like conventional combusted cigarettes, cigars, or pipes. They also can be small and portable, resembling pens or USB flash drives. Some ENDS are rechargeable and use a tank that can be filled with liquids; others, including disposables, are not.
In this study, ENDS aerosols produced by a blu rechargeable e-cigarette, a personal vaporiser and an eGo tank system were tested for their impact on the metabolic activity and viability of H292 bronchial epithelial cells in vitro. Exposure to ENDS aerosols caused a significant decrease in cell metabolic activity and a decrease in cell viability, as well as increased production of inflammatory cytokines IL-1b, IL-6 and CXCL1, compared with air controls.
We examined changes between prepriority enforcement (2018) and early postenforcement (February-June 2020) among adults on ENDS flavours, devices and flavour-device combinations used most often, and smoking and vaping behaviours. Findings indicate that while some adults stopped using cartridge/pod ENDS, half of those who continued to do so switched to device types and flavours exempt from the federal 2020 enforcement priority.
