SUMMARY

The potential presence of formaldehyde cyanohydrin in the polylactic acid (PLA) filter of Marlboro Heatstick when heated was reported by Davis B. et al., in Tobacco Control [Davis B, Williams M, Talbot P. iQOS: evidence of pyrolysis and release of a toxicant from plastic. Tob Control 2018; 0:1–8. doi: 10.1136/tobaccocontrol-2017-054104] but was not confirmed by using a reference standard. We decided to reproduce this work and were able to demonstrate unambiguously, using a reference standard, that formaldehyde cyanohydrin was not emitted by the PLA filter when heated.
