Description
Robert Thomas, Richard Rucker, Naudia Gray, and Steven Pappas wrote a white paper on the practical difficulties of measuring toxic metals in cannabis vape aerosols. Regulators need exposure numbers, but collecting the aerosol without contaminating it is notoriously hard. Metal levels are low, in the microgram-per-gram range, so stray contamination from collection gear can swamp the signal. Materials used to trap aerosols for organic analysis are unsuitable for metals work.
Some trapping approaches failed for a second reason: they resisted airflow, so devices would not activate and form aerosol properly. The paper reviews a decade of attempted methods, successful and not. It guides analytical chemists toward workable trapping designs. Reliable metal numbers underpin any future safety standards for cannabinoid delivery devices.
