This protocol describes a method for exposing rodents to electronic cigarette vapor (E-vapor) and cigarette smoke. Exposure chambers are constructed by modifying anesthesia chambers with an automated pumping system that delivers E-vapor or cigarette smoke to rodents. This system can easily be modified to accommodate many experimental endpoints.

Cannabis distillate vape cartridges are battery-powered devices that aerosolize extracts containing high concentrations of cannabinoids. The absence of established preclinical models for these products creates challenges in studying their physiological effects. To address this gap, a standardized preclinical inhalation murine model for vaporized cannabis distillates has been developed.

The physical form of a substance changes by changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. For vaporization to occur, kinetic energy must be greater than the intermolecular forces that keep molecules bonded. The amount of energy needed to vaporize a quantity of liquid at a given pressure and a constant temperature is called the heat of vaporization. When...

When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules move randomly about, they will occasionally collide with the surface of the condensed phase, and in some cases, these collisions will result in the molecules re-entering the condensed phase. The change from the gas phase to the liquid is called condensation. When the rate of condensation becomes equal to the rate of vaporization, neither the amount of the liquid nor the amount of the vapor...

FAQs
Device design and heating temperature can alter the aerosol’s composition, particle characteristics, and delivered dose. The source material identifies these variables, along with product composition, as determinants of what users and nearby people encounter. Comparing conditions therefore helps investigators connect a particular exposure profile with respiratory or cardiovascular responses rather than treating all vapor exposure as equivalent.
Separating vaporization from combustion matters because the exposure conditions are not interchangeable. Cannabis vapor exposure is studied specifically to determine how inhaled aerosols, rather than combustion-related emissions, affect the respiratory tract, bloodstream, and cardiovascular system. This comparison can clarify whether observed findings are associated with the heating approach, the product, or the resulting deposited material.
Particles and volatile compounds can deposit along the respiratory tract, while material reaching the lungs may pass into the bloodstream. This provides a mechanistic link between the inhaled aerosol and systemic responses, including cardiovascular effects. Researchers can use this pathway to examine how exposure characteristics influence where material is deposited and how it may contribute to effects beyond the lungs.
Cannabis products do not present a single chemical exposure. Measuring exposure requires attention to both cannabinoid content and the broader aerosol mixture. Tetrahydrocannabinol and cannabidiol may be accompanied by volatile compounds and particles, so product composition can influence the material inhaled, deposited in the respiratory tract, and available for uptake through the lungs.
A study may compare different devices, heating temperatures, or product compositions, then evaluate effects in users and people nearby. Relevant measurements include characteristics of the inhaled aerosol, respiratory responses, cardiovascular responses, secondhand exposure, and the distribution of material deposited in the respiratory tract. These comparisons help relate exposure conditions to biological outcomes.
Nearby people can inhale aerosol containing cannabinoids, volatile compounds, and particles, making bystander exposure a distinct medical research question. Studying it helps determine how the surrounding environment contributes to respiratory or cardiovascular responses and whether device design, temperature, or product composition changes what others encounter. This broadens assessment beyond the person directly using the device.
