Thanks for the info, steely!  I posted this late last night and didn't get around to reading the basic site info until this morning, I'll go back and clean some stuff up in a sec.  Also I'm aware 1.5g may seem like a lot, but it's also not very much really!  I will probably be sharing this among like minded friends on a few occasions, and from the troubles my friend has had trying to smoke the stuff (although personally I don't see how it can be as hard as he's made it out) then I'm afraid I'll blow through a decent portion of it before I get any worthwhile experiences.  Also should I be trying to titrate doses?  Or just go for the big one?
