Arcane:  By the way...dried leaves work perfectly well for quidding.  I haven't read the site rules lately to know if we can post vendors or not, but feel free to PM me if interested.  I recently purchased some organic leaves from an online vendor that accepts VISA cards that have worked exactly as expected.  This particular batch of leaves is also very bitter-less with almost no taste, which is nice.
I rehydrate a couple of grams with just a bit of water, and put whatever I do not eat back in a ziplock for later use over the next few days.  I personally use about 1/2 gram for a nice, light experience.  I chew it for about 10 minutes and the effects usually start around 10 minutes or so in.  Dosage takes a few trials to figure out exactly how much you need for the depth desired, but its easy to adjust.  If you try this, be sure to have a few hours available because if you do a heavy dose, it can last for well over 2 hours in my experience.
I have always been scared away from tinctures because the reports frequently sound painful...and simply chewing/eating the leaves works very well when done properly.
So when you're ready, I highly recommend chewing rehydrated leaves as an alternative to tinctures, until you have enough fresh leaves to use.
