Folks, freaking out while using stims isn't even stim psychosis.
Paranoia, anxiety, hostility, all of that can come with stims and it's NOT a matter of massive doses. You need to wash these drugs over dopamine receptors for a period of time before the real paranoia kicks in. With big doses that can be just a sustained 24 hour binge. But "bellringers" or whatever are not required for that.
Pyschosis is a whole nother complication. The psychotic person may not appear hostile or violent at all. She just knows about the code in the punctuation in the New Member Introductions and it's telling her messages about how her neighbors are planning to build a giant telescope that can see her wherever she goes.
You can get the paranoia at any dose, any ROA, freebase, acid salt, humid Texas powder-lumps, whatever.
And it's a sign you should sleep/slow-down before the real psychosis sets in. Getting too angry at your neighbor and accusing him of something minor is NOT paranoia or psychosis.
