简介：
Overview
This study establishes a standardized in vitro model for investigating cannabis vapor exposure at the air-liquid interface. The model aims to systematically examine the effects of vaporized cannabis, addressing the need for consistent methodologies in inhalation toxicology.
Key Study Components
Area of Science
- Inhalation toxicology
- Cannabis research
- Respiratory disease
Background
- Inhalation toxicology studies the health effects of various inhaled substances.
- Current research focuses on tobacco, e-cigarettes, and cannabis.
- Standardized methods for measuring compound deposition in advanced exposure systems are lacking.

Methods Used
- Utilization of a quartz crystal microbalance (QCM) for real-time dosimetry.
- Configuration of an inExpose exposure system for controlled vaporization.
- Calibration of QCMs for accurate mass calculations during exposure.
- Monitoring of vapor deposition and humidity levels throughout the exposure period.
Main Results
- Consistent delivery of delta nine tetrahydrocannabinol was observed across wells.
- QCM analysis indicated a steady increase in deposited mass over the exposure duration.
- Humidity levels were maintained effectively during the experiments.
- Real-time tracking of vapor deposition was successfully implemented.
Conclusions
- The developed model provides a reliable framework for studying cannabis vapor exposure.
- Standardized protocols enhance reproducibility in inhalation toxicology research.
