Welcome tex!
I was a soldier too. Don't have a lot to say about that, but I have drank ayahuasca to significant beneficial effect. For me at least, it's a very slow build that brings you to the intensity of a vaporized dmt experience, and then a slow return. Quite good for taking things out of the box and examining them. I don't think a religious approach is requisite.
Anyway, not to discourage you from vaping. I'm sure your soldier's courage will serve you well. I look forward to your posts.
