Auckland weeds

Hey,
I just wondered. I got a prescription for mariuhana back in Germany. It doesnt work though here in NZ. I definately need some weed soon though because my brain is somehow messed up and weed is the only medecine that actually works. Ive been walking around and asked here and there but no one was able to help me... Does anyone know about some place, some person who could hook me up? Im in serious trouble if i wont get any til tomorrow night... Im serious...
Id be thankfull for every help i can get from u, Jasper
