Does the vapour contain heavy metals?
Yes, minute traces of heavy metals such as lead or nickel can be found in vapor, but the levels detected remain extremely low and comparable to those permitted in inhaled medications. This phenomenon primarily affects high-power sub-ohm vaping, where coils are put under greater strain by high temperatures and intense usage.
As highlighted by consumer advocacy groups like AIDUCE, this is an area for constant industry improvement rather than a cause for alarm, given the actual daily exposure data. Manufacturers work daily on alloy purity to minimize these residues, even though they are already negligible compared to tobacco combustion. Keeping your equipment clean and adhering to recommended wattage ranges remains your best guarantee for chemically serene vapor.
