Interestingly, users often modified their puffing behavior to compensate for lower satisfaction, a factor which could influence real-world exposure levels. Overall, the review recommended further long-term studies but recognized that switching completely from cigarettes to HTP likely reduces health risks substantially. 2 Committees on Toxicity, Carcinogenicity and Mutagenicity (COT, COC, COM), UK COT, COC, and COM are scientific advisory groups commis- sioned by and serving the British government. As part of their work tasks, the committees jointly performed a toxicological evaluation of two HTP brands available in the UK, namely PMI's IQOS and BAT's glo, comparing their emissions and toxic profiles to those of combustible tobacco cigarettes. The results revealed a substantial decrease in exposure to several toxicants, with some HPHC reduced by 50% and others by more than 90%. Toxicology and cancer risks While some mutagenic and carcinogenic compounds were still present in HTP aerosol, their concentrations were considerably lower than those in cigarette smoke. Importantly, sidestream emissions in indoor environments were reduced, suggesting lower risks of secondhand exposure. Policy concerns and public messaging COT, COC, and COM emphasized that despite the reductions, HTP are not "safe" and should not appeal to non-smokers, par- ticularly youth. They called for continued independent research and surveillance to monitor population-level impacts and to in- form public health messaging appropriately. 3 German Federal Institute for Risk Assessment (BfR): Chemical and Toxicological Review BfR noted that unlike conventional cigarettes, which combust tobacco at over 700°C, HTP operate at approximately 350°C. This significant temperature drop drastically alters the emission profile, with independent studies reporting reductions of 80- 99% in aldehydes, polycyclic aromatic hydrocarbons (PAHs), and tobacco-specific nitrosamines (TSNA). Reduced metals and carbon monoxide Toxic heavy metals like cadmium and combustion byproducts such as carbon monoxide were also diminished by over 90%, the BfR study found, enhancing the evidence for reduced harm. Importantly, this analysis covered not only user exposure but also environmental output. Regulatory viewpoint While the reductions were notable, BfR nevertheless cautioned against interpreting them as a green light for unrestricted use.
