Thanks again, Loveall.  Apparently CA doesn't allow the full 190 proof version, but it seems that in this case that's probably a-ok.

Roughly how long did the oven-drying process take for your batch of 200ml everclear?

At the moment I'm pretty low on leaf so will likely use a small test batch of crude extract...probably along the lines of 45mg salvinorin...so I'm guessing the drying should go rather quickly.

I'm hoping this works for others that I've tried to introduce quidding to more so than for myself.  I'm lucky that I can use a tiny amount for a decent experience, so doubling or even quadrupling my standard amount of 0.75g of rehydrated leaf would be quite easy if I wanted a really strong experience.  But most friends I know that have tried tend to need so much that I don't blame them for giving up...

Hopefully I'll have something to report shortly after the new year!
