Second hand cigarette smoke is a mixture of mainstream and sidestream smoke. It contains the same toxicants as mainstream smoke, but at reduced levels. It is responsible for about 8% of the deaths caused by direct smoking.

 

Second hand mist from an e-cigarette is not smoke at all, and does not contain any substance known to cause death, short or long term, in the quantities found. It becomes  invisible within a few seconds, and is not detectable by smell.

 

Exhaled breath after e-cigarette use has been tested for CO only. No increase in CO was found.

 

The e-cigarette does not create side-stream smoke.

Exhaled breath after e-smoking contains even less nicotine per puff, as much of the nicotine inhaled is absorbed. Similarly, propylene glycol is largely absorbed and little is exhaled. 

 

No harm found in e-cigarette mist

 

Nicotine is not harmful in the quantities mentioned.1

 

Propylene glycol is harmless – it is used in making theatrical fog and as an ingredient in soaps, personal lubricants and intravenous medicines.
