Speed: dosage (volume) and best way to take?

[curious george]

Ok, first of all I want to make sure I didn't get ripped off. I bought a small chunk of meth the other day for $20. It was a bit larger than a pea, but I don't know its weight. Does this sound reasonable. Also, how much of it (volume again, not weight) makes a good dosage? I smoked maybe less than a third of the original amount and it didn't seem to do a lot, although I could still feel something. I'll probably do the rest (unless you guys think that's too much) tonight before I go to a bar. I don't have an option of smoking it this time as my roommates do not appreciate meth. So would it be about the same (as far as effects) to snort it as to just take it orally? I'd appreciate any input on this one as this is only my 2nd experience with speed.

If you are going to snort it prepare for it to hurt, a lot! However the burn doesnt last that long.
If I were you I'd snort a litle bump and see how you feel in 5-10mins then maybe do another. If your lump was the size of a pea so even assuming its totaly pure your not going to be able to do yourself too much damage just by caining the whole lot. Dont take my word on that though.

That sounds like a bit less than it should be, but not wildly off. Usually a twenty bag contains .1 g (100 mg)....was it in glass-like shards?
As for good dose, depends on the quality of your meth...
Personally, I would eat or smoke the rest of it. I don't like snorting meth, I find the high is jittery and the comedown shitty.
Definitely do the rest all at once though if you didn't get much from what you've done so far.
