Whitepaper: Cannabis series: Use of an Electrostatic Precipitator for the capture of cannabinoid (THC) aerosols.
Screening for metals in legal cannabis products, including vaping liquids, is required by multiple state legislatures. Colorado, in particular, the metals content in the aerosol phase, including mercury, arsenic, cadmium, and lead, is required to be measured.
The driving force in part for the determination of metals in cannabinoids (predominantly containing the lipid (-)-trans-delta-9-tetrahydrocannabinol which is commonly referred to as THC) is the known ability of Cannabis sativa plants to remediate metals from soils. Cannabis is so effective in phytoremediation within the environment that hemp (a non-psychoactive variety of cannabis) has been used as a tool in the bioremediation of metal-contaminated soils. The role of cannabis as a hyperaccumulator for various trace metals leads to concerns for high concentrations of toxic metals in any aerosol or smoke stream.
