Aerosol
An aerosol is a mixture of solid and/or liquid particles suspended in a gas. Aerosol examples include morning fog, mist from a spray bottle, or smoke from an active volcano.
AMES test
Ames test can identify chemicals that induce gene mutations (Mutagenicity).

Cig-a-likes
Cig-a-likes are the first generation of e-cigarettes which resemble the look and feel of a cigarette form.
Closed tank systems
Closed tank e-cigarettes use tailored or proprietary e-liquid capsules that can be easily replaced when empty or exchanged for another flavor.

Cytotoxicity
Cytotoxicity is the property of the substances that causes cellular death, functional or reproductive disfunction.
E-cigarettes
E-cigarettes have no tobacco and provide an inhalable vapor by electronically heating a nicotine-containing or nicotine-free liquid (e-liquid).
E-liquid
E-liquids are used to generate the vapor of an e-cigarette by being heated up by a battery. E-liquids consist of a carrier liquid, nicotine (not applicable for non-nicotine e-liquids) and flavors.
ETS
Environmental Tobacco Smoke
GC-olfactometry
GC(gas chromatography)-olfactometry is a method in which a mixture of chemical components is separated into individual components. Trained experts then smell each component to identify its specific odor.
Genotoxicity
Genotoxicity is a broader term. It includes mutagenicity, and it also includes DNA damage which may have mutagenicity, but may also be reversed by DNA repair or other cellular processes, and, thus, which may or may not result in permanent alterations in the structure or information content in a surviving cell or its offspring.
Harm reduction
"Harm reduction is a strategy used in medicine and social policy to minimize harm to individuals and/or wider society from hazardous behaviors or practices that cannot be completely avoided or prevented.” (“Nicotine Without Smoke,” Royal College of Physicians, 2016)
Heated tobacco products
Unlike e-cigarettes, heated tobacco products contain tobacco that is heated rather than combusted during use - producing an inhalable vapor containing evaporated constituents including nicotine and flavors.
High content analyses
High Content Analysis (HCA) is a cell-based assay that combines microscopy and image analysis. Using various fluorescent probes, HCA can capture morphological changes of individual cells and various changes inside cells as images, and perform quantitative analysis of the changes to be analyzed.

in vitro
“In vitro” means “within the glass” in Latin, indicating the various conditions artificially controlled which was historically a glass test tube. In vitro toxicological assessment is the scientific analysis to evaluate the effects of chemical substances on bacteria or cultured cells.
in vivo
“In vivo” means “within the living” in Latin, indicating the various conditions not artificially controlled in contrast to in-vitro. In-vivo toxicological assessment is the scientific analysis to evaluate the effects of chemical substances on entire living organisms, such as laboratory animals.
Indoor air quality
Indoor Air Quality (IAQ) generally refers to the condition of the air in and around the buildings where we work, live and spend free time: including its temperature, humidity, air flow and concentration of substances.

MN test
The MN (micronucleus) test identifies chemicals that induce chromosomal abnormalities.

Mutagenicity
Mutagenicity is the property of causing irreversible changes in the genetic information of an organism (DNA sequence or chromosomal structure and number). Mutagenicity is also found in radiation, ultraviolet rays, environmental pollutants, and other substances produced during food processing and cooking, and is known as a factor that induces cancer.
NRU test
The NRU (Neutral Red Uptake) test is a cytotoxicity test that evaluates the life/ death of mammalian cells.
Omics analyses
"Omics analysis" means a method of comprehensively investigating various molecules, such as DNA, RNA, proteins, and metabolites, which compose the living body, based on genomic information by combining analytical technology with computational science.
Open tank systems
Open tank e-cigarettes enable users to refill the device from special bottles containing e-liquids.
Organ-on-a-chip technology
Organ-on-a-chip technology is a new system culturing human cells on a microfluidic device. Organ-on-a-chip enables us to mimic the local physiological environment in humans.
Reduced-Risk Products
Reduced-Risk Products (RRP)* are the innovative products of JT Group. Different from conventional cigarettes, they are defined as having the potential to reduce the health risks associated with smoking. The most common RRP* are electronic cigarettes and heated tobacco products.
Toxicological assessments
Toxicological assessment is the scientific analysis to evaluate the effect of chemicals on the biological functions of organisms.

User experience
User experience (UX) generally refers to the experience that users get through products and services, including perceptions and cognitions during using them, and the overall impression which is created by this experience.
