Thanks crusher. Why don't I use shisha? Because until you just mentioned it, I didn't know it exists. In fact, I still don't. I guess I'll have to go look it up to see what it is
I'll look up kratom too.
I'm open to suggestions for other herbs that would act like a good filler. I didn't include them in my orig post because I was (and still am) under the impression that in general, the other herbs don't usually have a very good taste. Not that that's always true, but it's the impression I get. If you know of a good tasting herb that's not sold as "legal bud" then by all means, post it. I've been talking about legal bud because it seems that it's marketed based on it's taste.
Oh and crusher (and anyone else), IAS is the site I was referring to that had cheaper "legal bud" than the other sites. Anyway, I'm off to go look those two herbs up.
