Kate I know you don't use your I-Inhale with herbs, but what about a mix of the content in a passion flower tea bag+e-liquid? just as an experiment.
Yes, I might try that Lithium.
I quite like the idea of having a complimentary drink to have with a vape ... like tea and a vape naturally going together as a therapeutic break.
I have mental health problems though and take anti depressants and anti psychotic drugs so I have to be careful not to unbalance myself and cause a psychotic episode. This is the worst time of year for me so I don't think I'll mess about too much with chemicals until spring or summer.
The temperatures that substances vapourise at are very interesting, especially in regard to effectively modding new atomisers. I might start a thread about this at some point to get information together in one place.
