A few mgs would actually be a massive overdose. Doses are generally 300ug-1000ug (1mg). The only ways to really measure it out without insanely expensive equipment are to buy in a liquid solution or be 110% sure of the EXACT amount you have and make your own solution. That vendor died after taking 18mg, the only other death I've read in detail about is someone who stole a 35-40mg wrap from a friend and took it all assuming it was a dose. Like shermin says, vasoconstriction isn't really a problem unless you've overdosed though. On 1.25mg my skin appeared a bit pale and my hands felt a little stiff and cold but that was it.
that's karma and a half... but that doesn't sound nearly as bad as mephedrone vasoconstriction i've seen before...what kind of tolerance develops with ABDF?
Haha. I know, right? One of my friends feet go cold and numb pretty much every time he takes mephedrone now, he's had to give it up. I've never taken it often for an extended period of time so I dunno. I've done it two days running and got the same level of effect by taking 250ug extra though, so I can't imagine it being that bad.
