PG - Always use USP / BP PG for safety

OK I think this thread has run its course, so I'm closing it. Specific questions on health can be started in a new thread.

Some points:

- The FDA tried to ban e-cigarettes but were defeated in a court action that took a long time and cost a lot of money.

- Nobody is saying vaping is absolutely safe, it can't be, it just needs to be safer than smoking.

- It is extremely unlikely that e-cigs can cause any kind of cancer, but lung issues are another matter - especially if people don't take care.

- PG is much of a muchness, there cannot be too much variation. VG is another matter, as there are many ways of making it. It is virtually certain that some types are being used in e-liquid that should not be inhaled. People need to take much more care over what they buy, if they are interested in choosing the safest options.

- vaping very large amounts of unknown materials is not a safe procedure. Doing that is not a sensible route to optimum safety.

Mostly good info, but "PG is much of a muchness" is just not so.

One should always get USP / BP. It's a matter of purity vs contaminants, which for PG could be nasty.

Yes, you're right. I forgot to state that.

On another point though it's kind of related: I was looking at Dow Chemical's data sheets tonight, and was interested to note that they do support inhalation of glycerine, but do not support inhalation of PG.

Most people would probably think it was the other way round - but not so. Perhaps this is only in relation to their own materials.

Also, their glycerine for inhalation is clearly stated to be synthetic and not of vegetable origin.

In general, Dow does not support or recommend the use of PG in applications where inhalation exposure or human eye contact with the spray mists of these materials is likely, such as fogs for theatrical productions or antifreeze solutions for emergency eye wash stations.

Most reputable vendors use USP VG/PG.
