That's interesting - what % are you using? Is it an alcohol or glycerin extract?I have struggled with depression since I was 15. Name an antidepressant and I have probably been on it at one point or another. Effexor was probably the worst. The only problem with the e-cig is that plain nic. gives me too much anxiety, yet I tend to chain-vape, searching for that something that isn't there... the calming side. I weaned myself off antidepressants as I was tired of being a zombie. I prefer depression to a life of mechanical, zombie-like living, devoid of emotion. I do make an extraction of passionflower that I add to my e-cig. It really makes a huge difference in the level I vape. I get much more relaxation, much like a cig. As a result, I vape less than I did at first. I am not sure if any manufacturer uses PF, though some do use valerian, but that makes me too sleepy in the daytime.
I don't know, but since adding the PF (which acts as an mao inhibitor), I have been in a much better mood overall. There is a discussion here in the forums about it (do a search on MAOI, or passionflower). If you are currently on anti-depressants I wouldn't add it, as it could be too much. However, it is completely legal, and gives me the "calm" effect cigarettes provide.
Passionflower had a funny taste to me when I tried it - do you notice that?
And you're right, people on existing medications for depression probably shouldn't try it at all, but it's an intriguing discovery.
