i am quite experianced with anphetamines n stuff, meth is quite possible the WORST, but if she is experiancing that reaction so quickly, then then i dont thinks theres much to worry about.... substance induced disorders usually go either on the come down, or about a month later.. tell her to do ampetamine sulphate, mdma, or better coke if she wants to buzz out on a stimulant, keep her away from that stuff
