The manufacturers of propylene glycol, commonly used in e-liquids as a carrier of nicotine, should not be vaped.

Propylene glycol or PG is also used in numerous food products and is regarded as relatively safe, if ingested orally. It is not intended to be used for vaping as its toxic effects on the lung, eyes and throat may be greater and are largely unknown.

Although the manufacturers would stand to make more profit by selling propylene glycol for e-liquids, this warning may prevent multi-billion dollar lawsuits if lung diseases or cancers arise from the vaping of propylene glycol are found in the future.

The vaping smoke is not just harmless water vapor but contains many toxic chemicals, and the nicotine-containing e-liquids are just as addictive as cigarettes.

Incomplete Combustion and Thermal Degradation

Although the temperatures at which vaping occurs is lower than cigarettes, it is still quite elevated at 200to 250oC which causes some of the propylene glycol to convert to more toxic formaldehyde and acetaldehyde.

To help reduce the real risks of vaping, the following is recommended:

This is my first in a series of articles about the forensic aspects of nicotine, a much more addictive drug than either THC or alcohol.
