one of the components of the e-cig is polyethylene glycol.
This is currently being added to beta interferon injections used in Relapsing/remitting MS.
It has been proved to have a beneficial effect in making the actions of the beta interferon last longer in the bodies of those patients who are being prescribed it...meaning that weekly injections can now be given fortnightly and there is a study being done that suggests that the addition of this substance will eventually allow for the injections to be given on a monthly basis........so if it can be used for enhancing the effect of a very expensive kind of medication, then it is a good bet that inhaling this will be far less harmful than the inhaling of tobacco smoke
