Analysis of elemental impurities in cannabis following vaporization
The use of vaporizers to inhale cannabis is a technique that has risen in popularity among the American public. There is a general perception that vaporizers are “safer” when compared to more traditional cannabis smoking via combustion (i.e., cigarettes). The inherent use of heated air in vaporizers might reduce the respiratory toxicants or protein toxins by heating cannabis to a temperature where active compounds form in vapor phase. Yet this temperature is below the point of combustion where smoke and associated toxicants are produced. The elemental impurities are a general concern in all botanical products including cannabis and cannabis-derived products (CCDPs). This study aimed to investigate the potential transfer of those metallic elements from cannabis material to cannabis vapor through the vaporization process.
